ts-loader - npm Package Compare versions

Comparing version 9.5.4 to 9.5.7

AGENTS.md

+# AGENTS.md
+
+ts-loader is a TypeScript loader for webpack, enabling webpack to compile `.ts` and `.tsx` files via the TypeScript compiler.
+
+## Package manager
+
+Use `yarn` (not npm).
+
+## Key commands
+
+```bash
+yarn build              # compile src/ → dist/ (tsc --project "./src")
+yarn lint               # type-check + ESLint (no separate typecheck script)
+yarn test               # full test suite (comparison + execution tests)
+yarn comparison-tests   # fast subset: compare webpack output against snapshots
+yarn execution-tests    # run compiled code via Karma/Jasmine
+```
+
+To run a single test:
+```bash
+yarn comparison-tests -- --single-test <testName>
+yarn execution-tests  -- --single-test <testName> --watch
+```
+
+## Comparison tests (`test/comparison-tests/`)
+
+Each sub-directory is a mini webpack project. The harness compiles it and diffs the output against `expectedOutput/` snapshots (`bundle.js`, `output.txt`, `err.txt`). These are especially useful for failure cases — asserting that the right compiler errors appear.
+
+Full docs: [`test/comparison-tests/README.md`](test/comparison-tests/README.md)
+
+**Watch-mode tests** apply a series of patches (`patch0/`, `patch1/`, …) after the initial build, re-compiling and re-comparing after each one.
+
+**Flaky tests**: place an empty `_FLAKY_` file in the test directory to allow occasional failures without blocking the build.
+
+```bash
+yarn comparison-tests                                              # all tests
+yarn comparison-tests -- --single-test <name>                     # one test
+yarn comparison-tests -- --save-output                            # regenerate all snapshots
+yarn comparison-tests -- --save-output --single-test <name>       # regenerate one snapshot
+```
+
+> Note: test name casing must be exact when using `--single-test`.
+
+### Seeding snapshots for a new TypeScript version
+
+When adding support for a new TypeScript version, run:
+
+```bash
+yarn comparison-tests-generate
+```
+
+This does two things:
+1. `git clean -xfd test/comparison-tests` — wipes all untracked/generated files in the test directory.
+2. Runs `test/comparison-tests/stub-new-version.js`, which copies every `expectedOutput-{OLD}/` and `expectedOutput-transpile-{OLD}/` folder to the corresponding `expectedOutput-{NEW}/` counterpart across all test sub-directories.
+
+The `OLD_VERSION` and `NEW_VERSION` constants at the top of `stub-new-version.js` must be updated manually before running this script each time a new TypeScript version is introduced. After running, review and commit the seeded snapshots, then use `--save-output` to correct any that differ from the new version's actual output.
+
+## Execution tests (`test/execution-tests/`)
+
+Each sub-directory is a mini webpack project with a Karma/Jasmine test suite. The harness compiles the project and **runs the compiled code** — useful for asserting correct runtime behaviour. These are matrix-tested in CI across Node 20/22 and TypeScript 5.x versions.
+
+Full docs: [`test/execution-tests/README.md`](test/execution-tests/README.md)
+
+Tests prefixed with a TypeScript version (e.g. `2.0.3_es2016`) are skipped when the installed TypeScript is older than that prefix.
+
+Every `webpack.config.js` in this pack must include this alias so the local ts-loader is resolved:
+```js
+// for test harness purposes only
+module.exports.resolveLoader = { alias: { 'ts-loader': path.join(__dirname, "../../../index.js") } }
+```
+
+```bash
+yarn execution-tests                                    # all tests
+yarn execution-tests -- --single-test <name>            # one test
+yarn execution-tests -- --single-test <name> --watch    # watch mode (open http://localhost:9876/)
+```
+
+Always add or update tests when fixing bugs or adding features — see [CONTRIBUTING.md](CONTRIBUTING.md).
