Add an npm wrapper (package.json + postinstall downloader) so the Rust binary can be installed via npm/npx. Include a local smoke test, a GitHub Release cross-compile workflow, and nodejs in the dev shell. - package.json: idx-cli v0.2.3, bin idx, engines node>=16 - scripts/install.js: dependency-free postinstall that downloads the platform-specific GitHub Release asset (or IDX_BINARY_URL override) - scripts/idx.js: binary launcher preserving exit codes/signals - scripts/npm-smoke.sh: npm pack -> install tarball -> run idx --help and idx config --help, locale, no publish required - .github/workflows/release.yml: cross-compile linux-x64/arm64 and darwin-arm64 releases and attach binaries to the version tag - flake.nix: add nodejs_22 to the dev shell - docs/NPM_DISTRIBUTION.md: usage, local test, and release flow

# npm distribution
|
|
|
|
The npm package `idx-cli` is a small wrapper around the native `idx` binary.
|
|
The package keeps the JavaScript launcher and postinstall downloader. The
|
|
downloader selects a prebuilt GitHub Release asset for the current platform and
|
|
places it at the path used by the `idx` bin entry.
|
|
|
|
Supported release assets:
|
|
|
|
| npm platform | Rust target | Release asset |
|
|
| --- | --- | --- |
|
|
| Linux x64 | `x86_64-unknown-linux-gnu` | `idx-linux-x64` |
|
|
| Linux arm64 | `aarch64-unknown-linux-gnu` | `idx-linux-arm64` |
|
|
| macOS arm64 | `aarch64-apple-darwin` | `idx-darwin-arm64` |
|
|
|
|
Windows and other platform combinations are out of scope. The postinstall
|
|
script reports the supported targets when it rejects a platform.
|
|
|
|
## Use the package
|
|
|
|
```bash
|
|
npm install --global idx-cli
|
|
idx --help
|
|
|
|
# Or run the package without a global install.
|
|
npx idx-cli --help
|
|
```
|
|
|
|
The package version and the release tag must match. For example, package
|
|
version `0.2.3` downloads assets from the `v0.2.3` GitHub Release.
|
|
|
|
## Local smoke test
|
|
|
|
The smoke script builds or reuses `target/release/idx`, packs the npm wrapper,
|
|
installs the tarball into a new temporary directory, and runs the installed
|
|
`idx` command. It uses `IDX_BINARY_URL` with a local `file:` URL, so the test
|
|
does not need a registry publish or a network download.
|
|
|
|
```bash
|
|
nix develop -c bash -c 'scripts/npm-smoke.sh'
|
|
nix develop -c bash -c 'npm pack --dry-run'
|
|
```
|
|
|
|
The `prepare` npm script builds the Rust release binary when npm packs the
|
|
wrapper from this checkout. The `postinstall` script performs the release
|
|
download for normal package installation. `IDX_BINARY_URL` accepts an HTTP(S)
|
|
URL, a `file:` URL, or an existing local path for local testing.
|
|
|
|
## GitHub Release workflow
|
|
|
|
Pushing a tag that matches `v*` starts
|
|
`.github/workflows/release.yml`. The workflow builds all three supported Rust
|
|
targets, names the binaries with the asset names above, and attaches them to
|
|
the matching GitHub Release. The asset names and URLs must stay aligned with
|
|
`scripts/install.js`.
