The formatjs_intl_* polyfill crates expose ECMA-402 operations and owned C ABIs. formatjs_intl_hermes assembles their exports into one static archive. They remain independent of the higher-level formatjs_intl message runtime.

Cargo packages include generated metadata and Chromium's default locale set. Enable compiled_data on formatters to embed their locale records. Applications can also register locale records explicitly. Published packages require neither Node nor Bazel to compile.

Release Please manages versions and GitHub releases. The shared .github/workflows/crates-release.yml workflow validates with Bazel, assembles //crates:intl_release, and publishes through crates.io trusted publishing. Use its crate and dry_run inputs to validate a release without publishing.

bazel build //crates:intl_release assembles Cargo package sources with metadata, locale records, license notices, and Cargo build scripts. Bazel declares all inputs and runs its pinned Python toolchain; no separate preparation command is needed. DateTimeFormat extracts compressed records only with compiled_data.

The workflow exports release sources with git archive, overlays the Bazel package sources, then runs Cargo 1.97+ from that writable checkout. Keeping the full Cargo workspace preserves its checked-in lockfile. Cargo handles dependency order for selected Intl packages.

After a crate's initial publication, its owner must authorize formatjs/formatjs and workflow crates-release.yml in its crates.io trusted publishing settings.
