Convert src/common to TypeScript

This PR converts shared utilities and type definitions in src/common from JavaScript with Flow to TypeScript.

Changes

  • Converted common constants, messages, variables, keyboard events, prop types, and shared type modules to .ts
  • Preserved the original files as .js.flow definitions for backward compatibility
  • Updated affected TypeScript tests and fixtures for the migrated contracts
  • Added narrow @ts-expect-error comments to legacy consumers where changing production contracts could affect runtime behavior

Contract

  • Existing Flow contracts and runtime behavior are preserved
  • No executable production behavior was changed

Testing

  • Full Jest suite passes
  • yarn lint:ts passes
  • yarn flow check reports 0 errors
  • ESLint passes for all changed TypeScript files

Summary by CodeRabbit

  • New Features
    • Added shared definitions for content items, annotations, metadata, tasks, uploads, integrations, activity feeds, API responses, keyboard controls, and UI messages.
    • Added reusable localized labels and validation messages.
    • Added support for configuring a regional metadata API endpoint.
  • Tests
    • Updated test fixtures and coverage to align with the shared data definitions.
  • Refactor
    • Centralized common constants, colors, event names, and component property definitions.

Review Change Stack

Walkthrough

The PR adds shared Flow and TypeScript contracts for common UI data, Box entities, API payloads, metadata, feed items, tasks, integrations, logging, skills, and uploads. It also updates existing code and tests with migration suppressions and typed fixtures.

Changes

Shared contracts

Layer / File(s) Summary
Common primitives and messages
src/common/box-proptypes.*, src/common/constants.*, src/common/keyboard-events.*, src/common/messages.*, src/common/variables.*
Adds reusable PropTypes, constants, keyboard values, localized messages, and shared variables.
Core API and domain models
src/common/types/annotations.*, src/common/types/api.*, src/common/types/core.*, src/common/types/metadata.*, src/common/types/metadataQueries.*
Adds shared contracts for content items, collections, annotations, API requests and errors, metadata, and metadata queries.
Feature-specific models
src/common/types/feed.*, src/common/types/integrations.*, src/common/types/logging.*, src/common/types/skills.*, src/common/types/tasks.*, src/common/types/upload.*
Adds typed models for feed activity, integrations, metrics, Skills cards, tasks, and uploads.
Flow-to-TypeScript compatibility
src/elements/content-explorer/*, src/elements/content-sharing/*, src/elements/content-sidebar/*, src/elements/content-uploader/*
Adds @ts-expect-error directives for existing legacy type mismatches without changing runtime behavior.
Typed fixtures and validation
src/**/__tests__/*, src/elements/content-uploader/__tests__/*
Types test fixtures and helpers, adds required fields, preserves literal unions, and constructs complete upload records.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to 9ca2e

This migration preserves runtime behavior overall, but several TypeScript declarations do not match existing runtime contracts, which can weaken compile-time protection or cause incorrect typed consumers in upload and content-selection flows. The risk is bounded and mergeable with explicit owner follow-up to correct these shared callback and API typings.

A rabbit sorts the types in line
With carrots, commas, neat design
The fields now fit, the tests now grow
And legacy mismatches show
Shared contracts hop from file to file

Flow Function was mapped to any in several places, which drops callability. core.ts line 41 maps the same Flow Function to (...args: any[]) => any, so the migration is inconsistent and these fields now accept non-callable values.

  • src/common/types/upload.ts#L24-L25: type createReader and file as (...args: any[]) => any.

Centralize the task feed-item adapter.

FeedItems defines task entries with a narrower Task shape, while transformFeedItem converts them to TaskNew. Keep this intentional mismatch in one documented helper, or use a narrow @ts-expect-error at each boundary with the reason stated. Do not repeat as unknown as ActivityFeedV2Props['feedItems'].

TypeScript documentation allowJs false importing JavaScript module from TypeScript no declaration file TS7016

💡 Result:

The error TS7016: "Could not find a declaration file for module..." occurs when TypeScript attempts to import a JavaScript file but cannot verify its types because no declaration (.d.ts) file is provided and the compiler is not configured to process JavaScript files [1][2][3]. When allowJs is set to false (the default), TypeScript ignores JavaScript files during compilation and does not attempt to infer types from them, resulting in the TS7016 error [4][3]. To resolve this, you have three primary options: 1. Enable allowJs: The most direct solution is to set "allowJs": true in your tsconfig.json [4][1][5]. This allows TypeScript to import, type-check (if checkJs is enabled), and include JavaScript files in the compilation process [4][1]. 2. Create a Declaration File: If you prefer to keep allowJs as false, you can manually provide type information by creating a declaration file [3][6]. For a local module, create a file (e.g., globals.d.ts) in your project and add a module declaration: declare module './path/to/your/module' { const content: any; export default content; } This tells TypeScript to treat the module as having an 'any' type, bypassing the error [3][6]. 3. Use // @ts-ignore: If you need a quick workaround for a single import, you can place // @ts-ignore immediately above the import statement to suppress the TS7016 error [3][7]. If you are using a tool like Vite or a specific build setup, ensure that these settings are updated in the correct configuration file (e.g., tsconfig.app.json) rather than a base configuration that might be overridden [8][3][9].

Citations:


Provide TypeScript-visible declarations for these imports. tsconfig.json sets allowJs: false, and the three Flow modules have no corresponding declaration files. TypeScript cannot read their Flow annotations, so UploadItem.api and APIOptions.cache lose their API types and become untyped.

Align the callback types with the runtime contract.

ContentExplorer passes BoxItem[] to onSelect, onDownload, and onDelete, while ContentExplorerProps declares BoxItem. The legacy wrapper also defines these callbacks as BoxItem[], and the tests assert the array shape. Update the public types and consumers to use BoxItem[].
