Jul 2026 09:30:23 +0000 Subject: [PATCH 03/46] Convert @ldf/core to TypeScript Renames all lib/index source under packages/core to .ts, with a new packages/core/lib/types.ts holding shared interfaces (Query, DatasourceOptions, ControllerOptions, ViewSettings, LdfRequest/ LdfResponse, RenderDone, WorkerConfig, RouterRequest) used throughout the package. Converted bottom-up (Util/UrlData, datasources, views, controllers, routers, then the server/worker/CLI orchestration and index.ts), reusing real classes as types where possible instead of parallel duplicate interfaces (e.g. DatasourceRegistry = Record). core is first because every other package in the monorepo depends on it. Also extends .eslintrc/.gitignore/.eslintignore and adds a few more @types/* devDependencies the conversion needed.

charset=UTF-8 Content-Transfer-Encoding: 8bit Converts all 6 datasource packages (composite, hdt, jsonld, n3, rdfa, sparql) to TypeScript, each importing @ldf/core's types via deep path (@ldf/core/lib/types, @ldf/core/lib/datasources/Datasource) rather than the barrel index, since the barrel only re-exports runtime values. Two recurring type frictions handled pragmatically: lru-cache v5 (the actual declared dependency) has no bundled types and the monorepo's hoisted root lru-cache is an incompatible newer major, so it's pulled in untyped with a small hand-written structural type instead of an @types/* package; and rdf-js vs @rdfjs/types (used by hdt and jsonld-streaming-serializer) are structurally close but not always assignable, needing a narrow `as any` at those boundaries. Preserved as-is per the type-only philosophy: CompositeDatasource's _getDatasourceInfo passes 7 arguments to a 6-param inner function, so hasExactCount on the first call actually receives the callback itself (truthy, so it "works" by accident) — now called out with a comment instead of being silently typed away. Verified: typecheck, build, lint, and all 597 tests pass. --- .eslintignore | 24 +++++ .gitignore | 38 +++++++- .../{index.js => index.ts} | 2 +- ...teDatasource.js => CompositeDatasource.ts} | 78

Replaced the options.views as ViewCollection cast (and the `as any` it forced on the ViewCollection fallback constructor call) with a proper type guard, isViewCollection(). It preserves the original's exact duck-typing check (options.views && options.views.matchView) rather than switching to `instanceof`, which would reject any ViewCollection-like object that isn't a literal instance (e.g. test doubles) — a behavior change, not just a typing one.

The imprecision didn't disappear, it just moved to where it actually originates: Controller.ts's _baseUrl is built via lodash's mapValues, which shares one return type across all keys, so fields like `auth` end up typed string | boolean | undefined instead of the real string | null | undefined even though they can only hold strings.

These were defensive casts carried over from genuine rdf-js-vs-@rdfjs/types mismatches elsewhere in the conversion (hdt, jsonld-streaming-serializer's stream boundary) that didn't actually apply here. The one real duck-type — extension._generateRdf — now uses a type guard instead of a blind cast, same pattern as Controller.ts's isViewCollection: preserves the original's exact truthy check (extension._generateRdf), not instanceof or typeof === 'function'. Only one `any` remains in the file: context: Record in _createJsonLdWriter, a legitimate type (JSON-LD context values can be strings or nested objects), not a cast.

Removed as unnecessary: ViewCollection.ts's negotiate.choose cast, JsonLdDatasource.ts/RdfaDatasource.ts's parser constructor + .import() casts, N3Datasource.ts/SparqlDatasource.ts's constructor casts, LinkedDataFragmentsServer.ts's response.end.bind cast. Tightened from any to a real type: LinkedDataFragmentsServerWorker.ts's accesslogger params (LdfRequest/LdfResponse), readHttpsOption's any (unknown), Util.ts's error variable (Error), SparqlDatasource.ts's _convertLiteral param (Literal from rdf-js), CompositeDatasource.ts's exact local (inferred boolean), ExternalHdtDatasource.ts's parser (real Parser, casting only the two actual gaps individually instead of the whole variable). CliRunner.ts's ComponentsManager.build() options cast couldn't be dropped, but got more precise: cast to the real IComponentsManagerBuilderOptions instead of any, since the actual gap is mainModulePath not being statically guaranteed on the spread properties bag. Confirmed necessary and left alone: the for-in prototype-copy pattern in LinkedDataFragmentsServer.ts, protected cross-instance access (_config, _graph, _last/_first), _push calls (protected on asynciterator's BufferedIterator), the n3/hdt/@rdfjs-types boundary mismatches, and the two intentionally-preserved pre-existing bugs (findRecursive's arg count, the parseInt(match-array) coercion).

charset=UTF-8 Content-Transfer-Encoding: 8bit TS types `new SomeClass()` as SomeClass regardless of what the constructor body actually returns, so external callers of `new LinkedDataFragmentsServer(...)` were seeing none of LdfHttpServer's members. Fixed at the export boundary (a LinkedDataFragmentsServerConstructor cast on `export =`) rather than rewriting the class into a factory function, which would've renamed the export and risked breaking Components.js's `new`-based instantiation. This also let the worker's own redundant cast come out — `new LinkedDataFragmentsServer(config)` now infers correctly. Added _first?/_last? to the base Controller class. Verified this is a genuine shared framework convention, not one controller's private detail: feature-memento's TimegateController (not yet converted) also sets _first. Removes NotFoundController's redundant re-declaration and both any casts in LinkedDataFragmentsServerWorker.ts. Replaced two `as unknown as string` casts (SparqlDatasource.ts, ExternalHdtDatasource.ts) with String(limit)/String(offset) — same output as the original's implicit coercion (Array.join and child_process.spawn both stringify anyway), without lying to the type checker about what's actually in the array.

Verified: typecheck, build, lint, and all 597 tests pass. --- .eslintignore | 12 +++ .gitignore | 20 +++- package.json | 1 + .../feature-memento/{index.js => index.ts} | 2 +- ...nsion.js => MementoControllerExtension.ts} | 31 +++--- ...ateController.js => TimegateController.ts} | 94 ++++++++++++++----- .../QuadPatternFragmentsHtmlView-Memento.js | 28 ------ .../QuadPatternFragmentsHtmlView-Memento.ts | 34 +++++++ .../feature-summary/{index.js => index.ts} | 2 +- ...maryController.js => SummaryController.ts} | 30 ++++-- ...> QuadPatternFragmentsHtmlView-Summary.ts} | 11 ++- ...=> QuadPatternFragmentsRdfView-Summary.ts} | 14 +-- .../{SummaryRdfView.js => SummaryRdfView.ts} | 10 +- packages/feature-webid/{index.js => index.ts} | 2 +- ...tension.js => WebIDControllerExtension.ts} | 77 +++++++++------ yarn.lock | 5 + 16 files changed, 252 insertions(+), 121 deletions(-) rename packages/feature-memento/{index.js => index.ts} (96%) rename packages/feature-memento/lib/controllers/{MementoControllerExtension.js => MementoControllerExtension.ts} (58%) rename packages/feature-memento/lib/controllers/{TimegateController.js => TimegateController.ts} (65%) delete mode 100644 packages/feature-memento/lib/views/memento/QuadPatternFragmentsHtmlView-Memento.js create mode 100644 packages/feature-memento/lib/views/memento/QuadPatternFragmentsHtmlView-Memento.ts rename packages/feature-summary/{index.js => index.ts} (96%) rename packages/feature-summary/lib/controllers/{SummaryController.js => SummaryController.ts} (66%) rename packages/feature-summary/lib/views/summary/{QuadPatternFragmentsHtmlView-Summary.js => QuadPatternFragmentsHtmlView-Summary.ts} (70%) rename packages/feature-summary/lib/views/summary/{QuadPatternFragmentsRdfView-Summary.js => QuadPatternFragmentsRdfView-Summary.ts} (56%) rename packages/feature-summary/lib/views/summary/{SummaryRdfView.js => SummaryRdfView.ts} (54%) rename packages/feature-webid/{index.js => index.ts} (92%) rename packages/feature-webid/lib/controllers/{WebIDControllerExtension.js => WebIDControllerExtension.ts} (55%) diff --git a/.eslintignore b/.eslintignore index e7b7b026..6179772c 100644 --- a/.eslintignore +++ b/.eslintignore @@ -31,3 +31,15 @@ packages/datasource-hdt/lib/**/*.js packages/datasource-hdt/lib/**/*.d.ts packages/datasource-hdt/index.js packages/datasource-hdt/index.d.ts +packages/feature-webid/lib/**/*.js +packages/feature-webid/lib/**/*.d.ts +packages/feature-webid/index.js +packages/feature-webid/index.d.ts +packages/feature-summary/lib/**/*.js +packages/feature-summary/lib/**/*.d.ts +packages/feature-summary/index.js +packages/feature-summary/index.d.ts +packages/feature-memento/lib/**/*.js +packages/feature-memento/lib/**/*.d.ts +packages/feature-memento/index.js +packages/feature-memento/index.d.ts diff --git a/.gitignore b/.gitignore index 8ca677b9..c3976a39 100644 --- a/.gitignore +++ b/.gitignore @@ -57,4 +57,22 @@ packages/datasource-hdt/lib/**/*.js.map packages/datasource-hdt/lib/**/*.d.ts packages/datasource-hdt/index.js packages/datasource-hdt/index.js.map -packages/datasource-hdt/index.d.ts \ No newline at end of file +packages/datasource-hdt/index.d.ts +packages/feature-webid/lib/**/*.js +packages/feature-webid/lib/**/*.js.map +packages/feature-webid/lib/**/*.d.ts +packages/feature-webid/index.js +packages/feature-webid/index.js.map +packages/feature-webid/index.d.ts +packages/feature-summary/lib/**/*.js +packages/feature-summary/lib/**/*.js.map +packages/feature-summary/lib/**/*.d.ts +packages/feature-summary/index.js +packages/feature-summary/index.js.map +packages/feature-summary/index.d.ts +packages/feature-memento/lib/**/*.js +packages/feature-memento/lib/**/*.js.map +packages/feature-memento/lib/**/*.d.ts +packages/feature-memento/index.js +packages/feature-memento/index.js.map +packages/feature-memento/index.d.ts \ No newline at end of file diff --git a/package.json b/package.json index 26bdbcae..16f87110 100644 --- a/package.json +++ b/package.json @@ -11,6 +11,7 @@ "@types/lodash": "^4.17.24", "@types/mime": "^2.0.3", "@types/node": "^22.20.1", + "@types/parse-cache-control": "^1.0.4", "@types/q": "^1.5.8", "@types/request": "^2.48.13", "@typescript-eslint/eslint-plugin": "^5.62.0", diff --git a/packages/feature-memento/index.js b/packages/feature-memento/index.ts similarity index 96% rename from packages/feature-memento/index.js rename to packages/feature-memento/index.ts index 7aacdcf7..b28237fe 100644 --- a/packages/feature-memento/index.js +++ b/packages/feature-memento/index.ts @@ -1,7 +1,7 @@ /*! @license MIT ©2015-2016 Ruben Verborgh, Ghent University -

Added a Router interface (extractQueryParams) local to QuadPatternFragmentsController.ts, and reused Controller itself as the type for controller extensions (its public handleRequest signature is exactly what the extension loop calls). Query gains an optional patternString field in @ldf/core's types.ts, populated by the controller and read back by the RDF view. Typed settings.results as the real AsyncIterator it always is at runtime (rather than settings' own ambient `any`), and its 'metadata' property as the {totalCount, hasExactCount} shape every datasource implementation actually sets — matching the precedent in CompositeDatasource.ts rather than falling back to any. subject/predicate/object/graph in _createPatternString, and hasTriplePattern/hasQuadPattern in QuadPatternRouter, stay any: each is reused across a Term and a formatted string within the same variable, the same pattern already confirmed necessary in TimegateController's mementoUrl/originalUrl.

Tuned three rules for noise specific to this codebase: prefer-const off (let is the pervasive style throughout), restrict-plus-operands with allowNumberAndString (plain 'text ' + number is safe and everywhere here), unbound-method off (every hit is a destructured DataFactory method or lodash's _.noop, none of which use `this`). Fixed all resulting findings across core and every package by replacing `as any` with `as unknown as ` at each protected/ internal-API access point, and giving several loosely-typed view helper params real types (AsyncIterator, {totalCount, hasExactCount}, a FragmentInfo/DatasourceInfo pair in QuadPatternFragmentsRdfView.ts that dropped that file from 63 findings to 0). Genuine Term/undefined/Error-into-string concatenations got narrow casts at their exact site instead. Follow-up pass, since several of those casts could be real types instead of asserted ones: - Datasource._graph and LinkedDataFragmentsServerWorker._config dropped `protected` (compile-time-only change, no runtime effect), removing the cast at their two call sites entirely. - LinkedDataFragmentsServer's three prototype methods now use `declare` class members instead of casting the prototype to a Pick<...> type at each assignment site. `declare` emits no code, so the actual `.prototype.x = function(){}` assignments (still required for the for...in enumerability the constructor relies on) remain the only real implementation. - n3's Parser gets its undocumented `_prefixes` and static `_resetBlankNodePrefix` declaration-merged into its own types (types/n3-augment.d.ts, confirmed against n3's actual source), so every access is now a normal checked property read instead of a local cast repeated per call site. Confirmed (empirically, via a throwaway augmentation) that BufferedIterator._push can't be fixed the same way: declaration merging can add the type, but asynciterator's own `protected` still blocks access at every call site. Its 5 casts stay as the only way to call a genuinely protected method from outside its class hierarchy. Verified: typecheck, build, lint (0 problems), and all 597 tests pass. --- .eslintrc | 22 ++++++++++++++- packages/core/lib/CliRunner.ts | 14 +++++----- .../core/lib/LinkedDataFragmentsServer.ts | 21 +++++++++------ .../lib/LinkedDataFragmentsServerWorker.ts | 6 ++--- packages/core/lib/Util.ts | 4 +-- packages/core/lib/controllers/Controller.ts | 6 ++--- .../lib/controllers/NotFoundController.ts | 2 +- packages/core/lib/datasources/Datasource.ts | 2 +- .../core/lib/datasources/MemoryDatasource.ts | 2 +- packages/core/lib/views/HtmlView.ts | 4 +-- packages/core/lib/views/RdfView.ts | 9 ++++--- .../lib/datasources/CompositeDatasource.ts | 16 ++++++----- .../lib/datasources/ExternalHdtDatasource.ts | 13 ++++----- .../lib/datasources/HdtDatasource.ts | 2 +- .../lib/datasources/N3Datasource.ts | 2 +- .../lib/datasources/SparqlDatasource.ts | 11 ++++---- .../controllers/MementoControllerExtension.ts | 8 +++--- .../lib/controllers/TimegateController.ts | 6 ++--- .../QuadPatternFragmentsHtmlView-Memento.ts | 2 +- .../QuadPatternFragmentsController.ts | 7 ++--- .../QuadPatternFragmentsHtmlView.ts | 2 +- .../QuadPatternFragmentsRdfView.ts | 27 +++++++++++++------ .../QuadPatternFragmentsHtmlView-Summary.ts | 4 +-- .../QuadPatternFragmentsRdfView-Summary.ts | 8 +++--- .../lib/views/summary/SummaryRdfView.ts | 6 +++-- .../controllers/WebIDControllerExtension.ts | 8 +++--- types/n3-augment.d.ts | 14 ++++++++++ types/shims.d.ts | 13 ++++++--- 28 files changed, 153 insertions(+), 88 deletions(-) create mode 100644 types/n3-augment.d.ts diff --git a/.eslintrc b/.eslintrc index bea3c253..77e76b5c 100644 --- a/.eslintrc +++ b/.eslintrc @@ -202,6 +202,7 @@ // TypeScript source files files: [ "packages/**/*.ts" ], parser: "@typescript-eslint/parser", + extends: [ "plugin:@typescript-eslint/recommended-requiring-type-checking" ], parserOptions: { ecmaVersion: 9, sourceType: "module", @@ -218,7 +219,26 @@ // for one implementation) — the TS compiler already validates those.

Replaced with `as unknown as X` (matches the Term-reuse cast pattern) everywhere the original JS gracefully degrades rather than crashes, which `!` was misrepresenting as a guarantee: - PageRouter's config.pageSize! (the code calls isFinite() on it, which only makes sense if it might not be a valid number) - HdtDatasource/ExternalHdtDatasource's query.limit! (same shape as the QuadPatternFragmentsRdfView.ts fix — NaN-comparison, no crash) - TimegateController's version.datasourceId! (undefined as an object key just becomes the literal key "undefined") - SparqlDatasource's four remaining _encodeObject(...)! calls on general Term inputs (push/join or string-concat both tolerate null) Eliminated the assertion entirely in RdfView.ts: `declare dataFactory: DataFactory` on the class replaces three separate this.dataFactory! reads. View's own dataFactory is optional only because HtmlView doesn't need one — every RdfView subclass does. That fix cascaded to QuadPatternFragmentsRdfView-Summary.ts, where four more this.dataFactory! reads had become genuinely unnecessary once the base type was corrected. Confirmed and left alone: assertions backed by a real invariant, either provable by construction (regexes that structurally always match, like /[^;,]*/ and /^(?:([a-z]+):)?/) or enforced by a single controlled call path in our own code (request.url/parsedUrl, always set before any _handleRequest override can run; ErrorController's response.error, set at its one and only call site immediately before use). Not fixed, flagged instead: WebIDControllerExtension's settings.urlData!.protocol and IndexDatasource's delete this._datasources!['/'] both depend on deployment config supplying a value, same as PageRouter, but without a graceful fallback — if wrong, they throw. A cast wouldn't reduce that risk, only relabel it; a real fix means a runtime guard, which is a behavior change, not a typing one.

Casting would only have relabeled that risk, not reduced it, so these get real fallbacks instead: - WebIDControllerExtension: settings.urlData!.protocol now defaults via `settings.urlData || new UrlData()`, the same fallback pattern Controller's own constructor already uses for this exact field. With no urlData configured, protocol defaults to 'http', so the existing `_protocol !== 'https'` gate quietly skips WebID enforcement instead of crashing Components.js instantiation. - IndexDatasource: options.datasources now falls back to `{}` via the `x || {}` idiom already used throughout this codebase, so _datasources is genuinely an object by the time it's deleted from. The field's own type stays optional (_datasources?), since _getAllQuads deliberately deletes it later to free memory once quads are generated — it's meant to go back to undefined over the object's lifetime.

Replaced with String(x)/Number(x), which carries the same coercion without asserting a lie about the type. The remaining twelve files keep the cast, exempted from the rule at the file level rather than with inline eslint-disable comments (per feedback — too much noise for this many call sites): protected third-party member access confirmed unfixable by declaration merging, constructor-return-type mismatches, and deliberate signature violations that were already reviewed individually across the last few commits. Verified: typecheck, build, lint (0 problems), and all 597 tests pass. --- .eslintrc | 33 ++++++++++++++++++- .../lib/LinkedDataFragmentsServerWorker.ts | 2 +- packages/core/lib/UrlData.ts | 2 +- packages/core/lib/routers/PageRouter.ts | 2 +- .../lib/datasources/CompositeDatasource.ts | 2 +- .../lib/datasources/ExternalHdtDatasource.ts | 2 +- .../lib/datasources/HdtDatasource.ts | 2 +- .../lib/controllers/TimegateController.ts | 2 +- .../QuadPatternFragmentsRdfView.ts | 4 +-- .../controllers/WebIDControllerExtension.ts | 2 +- 10 files changed, 42 insertions(+), 11 deletions(-) diff --git a/.eslintrc b/.eslintrc index 77e76b5c..fde6a820 100644 --- a/.eslintrc +++ b/.eslintrc @@ -238,7 +238,38 @@ "@typescript-eslint/unbound-method": "off", // no-floating-promises' own suggested fix for an intentionally-unawaited // promise chain is prefixing it with `void`. - "no-void": [ 2, { allowAsStatement: true } ] + "no-void": [ 2, { allowAsStatement: true } ], + // `x as unknown as Y` opts out of type checking entirely for x.

Node fell back to loading the .ts source directly - recent versions can natively strip plain type annotations, but not `import X = require(...)`, which needs real transformation rather than erasure. That's this codebase's standard import syntax throughout, hence the SyntaxError: Unexpected token '=' on nearly every test file. Reproduced locally by moving out all 168 locally-built compiled files (simulating a from-scratch checkout) and running test-ci - identical stack trace, down to the line and column. Confirmed the fix by adding the build step and rerunning the same sequence: 597/597 passing. --- .github/workflows/ci.yml | 2 ++ 1 file changed, 2 insertions(+) diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index 401fe2a1..07b78ebd 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -40,6 +40,8 @@ jobs: key: ${{ runner.os }}-test-modules-${{ hashFiles('**/yarn.lock') }} - name: Install dependencies run: yarn install + - name: Build TypeScript + run: yarn run build - name: Run tests run: yarn run test-ci - name: Submit coverage results From 97b2507b17c935ed0b194aa32d2eb9cdc25270c1 Mon Sep 17 00:00:00 2001 From: Michiel Date: Wed, 29 Jul 2026 13:17:53 +0000 Subject: [PATCH 23/46] Add tests for the three previously-untested packages/files IndexDatasource, WebIDControllerExtension, TimegateController, and MementoControllerExtension have never had tests at any point in this project's ~10-year history (traced back to their original introducing commits) - not a regression from the TS migration, a pre-existing gap. Two of them (IndexDatasource, TimegateController) got real behavior changes during this migration's ! and cast audits, which is the concrete reason to close the gap now rather than defer it further. IndexDatasource: full coverage of the constructor's datasources fallback (confirmed meaningful by reverting the fix and watching the test reproduce the exact crash) and quad generation (visible/hidden/ no-URL/"/"-excluded datasources). TimegateController + MementoControllerExtension: the date-matching algorithm including the gap-between-intervals case, the static map-building methods (including today's String(datasourceId) fix, though that turned out to be a pure honesty improvement with no behavior difference from the cast it replaced), and request handling via both DummyServer/supertest and direct method invocation. WebIDControllerExtension: covers what's actually reachable. The class can't be constructed - lru-cache v5 is a class and the constructor calls it as a plain function, a pre-existing bug preserved as-is - and _verifyWebID crashes the same way on n3's Parser before reaching any of its real logic. Rather than fake coverage, one test documents that construction throws (so it fails loudly if that ever changes), and the two methods that are reachable without hitting either crash (_handleRequest's protocol gate, _handleNotAcceptable's formatting) are tested directly against the prototype. Added the missing test/.eslintrc (mocha globals) to feature-webid and feature-memento, since neither test directory existed before. All plain .js/mocha/chai/sinon, matching every other test in the suite - deferred vitest migration applies here too. Verified: typecheck, build, lint (0 problems), and the full suite (645 passing, up from 597) all clean. --- .../test/datasources/IndexDatasource-test.js | 119 ++++++++++++ packages/feature-memento/test/.eslintrc | 18 ++ .../MementoControllerExtension-test.js | 92 +++++++++ .../controllers/TimegateController-test.js | 179 ++++++++++++++++++ packages/feature-webid/test/.eslintrc | 18 ++ .../WebIDControllerExtension-test.js | 67 +++++++ 6 files changed, 493 insertions(+) create mode 100644 packages/core/test/datasources/IndexDatasource-test.js create mode 100644 packages/feature-memento/test/.eslintrc create mode 100644 packages/feature-memento/test/controllers/MementoControllerExtension-test.js create mode 100644 packages/feature-memento/test/controllers/TimegateController-test.js create mode 100644 packages/feature-webid/test/.eslintrc create mode 100644 packages/feature-webid/test/controllers/WebIDControllerExtension-test.js diff --git a/packages/core/test/datasources/IndexDatasource-test.js b/packages/core/test/datasources/IndexDatasource-test.js new file mode 100644 index 00000000..17ce6139 --- /dev/null +++ b/packages/core/test/datasources/IndexDatasource-test.js @@ -0,0 +1,119 @@ +/*! @license MIT ©2014-2016 Ruben Verborgh, Ghent University - imec */ +let IndexDatasource = require('../../lib/datasources/IndexDatasource');

Trims the no-restricted-syntax exemption list down to the one remaining case (HdtDatasource's constructor swapping in a sibling class instance), which needs a real architectural change to resolve.

Adds a real overload to n3's Parser#parse for the stream-input case (verified against N3Lexer's actual source: it branches on typeof input, duck-typing setEncoding/on('data'|'end'|'error') otherwise), removing the `as any` casts in ExternalHdtDatasource and N3Datasource that were bridging around the missing overload. Also replaces the remaining as-any casts in HdtDatasource (dataFactory param narrowed to hdt.fromFile's own declared parameter type; the close().then callback pair no longer needs casting once the fulfilled branch is adapted to hdt's void resolution) and ExternalHdtDatasource (parseInt's match array replaced with the actual matched string). Makes the LinkedDataFragmentsServer http.createServer() branch route through net.Server the same way the https branch already needs to, instead of one branch getting a shorter cast than the other for no documented reason. Also drops three no-op `no-redeclare` eslint-disable comments left over from the namespace-merge pattern — the rule is already off for all .ts files.
