Summary

  • Adds --minify to all bun build invocations: the cli.js bundle, the local --compile binary, and the cross-platform release build in scripts/build.ts.
  • Reduces the shipped clerk binary by ~1 MB on every target (63.38 MB → 62.39 MB on darwin-arm64 measured locally).
  • Reduces the bundled cli.js artifact by ~41% (2.37 MB → 1.40 MB).
  • No behavior change. --define-injected values (CLI_VERSION, CLI_ENV_PROFILES) are unaffected because Bun substitutes defines before minification.

Why minify only

Reduction beyond --minify requires changing the deploy model (the embedded Bun runtime is ~60 MB of the binary and is fixed). I evaluated and rejected:

  • --target=bun (the default) — grew the bundle: 1.40 MB → 1.63 MB.
  • --sourcemap=none on --compile — grew the binary by 1.85 MB (Bun quirk; default behavior is smaller).
  • --bytecode — fails on cli.ts's top-level await import() for the completion fast path; bytecode also typically increases output size.
  • Switching @inquirer/prompts to per-package imports — tree-shaking already eliminates unused prompts (verified: 360 KB used vs 420 KB if import * as).

Test plan

  • bun run build produces cli.js of 1,400,498 B (down from 2,372,203 B)
  • bun run build:compile produces dist/clerk of 62,388,832 B (down from 63,379,552 B)
  • bun run scripts/build.ts --target darwin-arm64 --version 0.0.0-test succeeds and the binary reports the injected version
  • bun run typecheck passes
  • bun run lint passes
  • bun run format:check passes
  • bun run test — all 82 unit + integration tests pass
  • Manual smoke on the minified compiled binary: --version, --help, apps --help, init --help, completion bash all behave correctly
  • CI runs bun changeset status --since=origin/main (verified locally with staged changeset: exits 0, "clerk: patch")
  • CI runs bun run test:e2e against the source (not the compiled binary), so minify is not exercised but also not broken

Walkthrough

This change enables build minification across the CLI build pipeline. A changeset metadata file documents the patch release for the clerk package. The build and build:compile scripts in packages/cli-core/package.json add the --minify flag to Bun build invocations. The main build script in scripts/build.ts adds --minify to the Bun compile command for selected targets. These modifications reduce the output bundle sizes without altering functionality.

perf(build): minify bundle and compiled binary
6ac3b1b
Adds `--minify` to `bun build` and `bun build --compile` invocations in
`packages/cli-core/package.json` and the cross-platform release builder
in `scripts/build.ts`.
Reduces the shipped `clerk` binary by ~1 MB across all platforms
(63.38 MB → 62.39 MB on darwin-arm64 locally) and the bundled `cli.js`
artifact by ~41% (2.37 MB → 1.40 MB). No behavior change: tests,
typecheck, lint, format and end-to-end binary smoke (`--version`,
`--help`, `apps`, `init --help`, `completion bash`) all pass.
Bun applies `--define` substitutions before minification, so
`CLI_VERSION` and `CLI_ENV_PROFILES` injection continue to work; the
release smoke test (compiled binary `--version`) still matches the
injected version.

perf(build): minify bundle and compiled binary
6ac3b1b
Adds `--minify` to `bun build` and `bun build --compile` invocations in
`packages/cli-core/package.json` and the cross-platform release builder
in `scripts/build.ts`.
Reduces the shipped `clerk` binary by ~1 MB across all platforms
(63.38 MB → 62.39 MB on darwin-arm64 locally) and the bundled `cli.js`
artifact by ~41% (2.37 MB → 1.40 MB). No behavior change: tests,
typecheck, lint, format and end-to-end binary smoke (`--version`,
`--help`, `apps`, `init --help`, `completion bash`) all pass.
Bun applies `--define` substitutions before minification, so
`CLI_VERSION` and `CLI_ENV_PROFILES` injection continue to work; the
release smoke test (compiled binary `--version`) still matches the
injected version.

This change enables build minification across the CLI build pipeline. A changeset metadata file documents the patch release for the clerk package. The build and build:compile scripts in packages/cli-core/package.json add the --minify flag to Bun build invocations. The main build script in scripts/build.ts adds --minify to the Bun compile command for selected targets. These modifications reduce the output bundle sizes without altering functionality.

perf(build): minify bundle and compiled binary
6ac3b1b
Adds `--minify` to `bun build` and `bun build --compile` invocations in
`packages/cli-core/package.json` and the cross-platform release builder
in `scripts/build.ts`.
Reduces the shipped `clerk` binary by ~1 MB across all platforms
(63.38 MB → 62.39 MB on darwin-arm64 locally) and the bundled `cli.js`
artifact by ~41% (2.37 MB → 1.40 MB). No behavior change: tests,
typecheck, lint, format and end-to-end binary smoke (`--version`,
`--help`, `apps`, `init --help`, `completion bash`) all pass.
Bun applies `--define` substitutions before minification, so
`CLI_VERSION` and `CLI_ENV_PROFILES` injection continue to work; the
release smoke test (compiled binary `--version`) still matches the
injected version.

Summary
  • Adds --minify to all bun build invocations: the cli.js bundle, the local --compile binary, and the cross-platform release build in scripts/build.ts.
  • Reduces the shipped clerk binary by ~1 MB on every target (63.38 MB → 62.39 MB on darwin-arm64 measured locally).
  • Reduces the bundled cli.js artifact by ~41% (2.37 MB → 1.40 MB).
  • No behavior change. --define-injected values (CLI_VERSION, CLI_ENV_PROFILES) are unaffected because Bun substitutes defines before minification.
Why minify only
Reduction beyond --minify requires changing the deploy model (the embedded Bun runtime is ~60 MB of the binary and is fixed). I evaluated and rejected:
  • --target=bun (the default) — grew the bundle: 1.40 MB → 1.63 MB.
  • --sourcemap=none on --compile — grew the binary by 1.85 MB (Bun quirk; default behavior is smaller).
  • --bytecode — fails on cli.ts's top-level await import() for the completion fast path; bytecode also typically increases output size.
  • Switching @inquirer/prompts to per-package imports — tree-shaking already eliminates unused prompts (verified: 360 KB used vs 420 KB if import * as).
Test plan
  • bun run build produces cli.js of 1,400,498 B (down from 2,372,203 B)
  • bun run build:compile produces dist/clerk of 62,388,832 B (down from 63,379,552 B)
  • bun run scripts/build.ts --target darwin-arm64 --version 0.0.0-test succeeds and the binary reports the injected version
  • bun run typecheck passes
  • bun run lint passes
  • bun run format:check passes
  • bun run test — all 82 unit + integration tests pass
  •  Manual smoke on the minified compiled binary: --version, --help, apps --help, init --help, completion bash all behave correctly
  •  CI runs bun changeset status --since=origin/main (verified locally with staged changeset: exits 0, "clerk: patch")
  •  CI runs bun run test:e2e against the source (not the compiled binary), so minify is not exercised but also not broken

perf(build): minify bundle and compiled binary
6ac3b1b
Adds `--minify` to `bun build` and `bun build --compile` invocations in
`packages/cli-core/package.json` and the cross-platform release builder
in `scripts/build.ts`.
Reduces the shipped `clerk` binary by ~1 MB across all platforms
(63.38 MB → 62.39 MB on darwin-arm64 locally) and the bundled `cli.js`
artifact by ~41% (2.37 MB → 1.40 MB). No behavior change: tests,
typecheck, lint, format and end-to-end binary smoke (`--version`,
`--help`, `apps`, `init --help`, `completion bash`) all pass.
Bun applies `--define` substitutions before minification, so
`CLI_VERSION` and `CLI_ENV_PROFILES` injection continue to work; the
release smoke test (compiled binary `--version`) still matches the
injected version.

perf(build): minify bundle and compiled binary
6ac3b1b
Adds `--minify` to `bun build` and `bun build --compile` invocations in
`packages/cli-core/package.json` and the cross-platform release builder
in `scripts/build.ts`.
Reduces the shipped `clerk` binary by ~1 MB across all platforms
(63.38 MB → 62.39 MB on darwin-arm64 locally) and the bundled `cli.js`
artifact by ~41% (2.37 MB → 1.40 MB). No behavior change: tests,
typecheck, lint, format and end-to-end binary smoke (`--version`,
`--help`, `apps`, `init --help`, `completion bash`) all pass.
Bun applies `--define` substitutions before minification, so
`CLI_VERSION` and `CLI_ENV_PROFILES` injection continue to work; the
release smoke test (compiled binary `--version`) still matches the
injected version.

Summary
  • Adds --minify to all bun build invocations: the cli.js bundle, the local --compile binary, and the cross-platform release build in scripts/build.ts.
  • Reduces the shipped clerk binary by ~1 MB on every target (63.38 MB → 62.39 MB on darwin-arm64 measured locally).
  • Reduces the bundled cli.js artifact by ~41% (2.37 MB → 1.40 MB).
  • No behavior change. --define-injected values (CLI_VERSION, CLI_ENV_PROFILES) are unaffected because Bun substitutes defines before minification.
Why minify only
Reduction beyond --minify requires changing the deploy model (the embedded Bun runtime is ~60 MB of the binary and is fixed). I evaluated and rejected:
  • --target=bun (the default) — grew the bundle: 1.40 MB → 1.63 MB.
  • --sourcemap=none on --compile — grew the binary by 1.85 MB (Bun quirk; default behavior is smaller).
  • --bytecode — fails on cli.ts's top-level await import() for the completion fast path; bytecode also typically increases output size.
  • Switching @inquirer/prompts to per-package imports — tree-shaking already eliminates unused prompts (verified: 360 KB used vs 420 KB if import * as).
Test plan
  • bun run build produces cli.js of 1,400,498 B (down from 2,372,203 B)
  • bun run build:compile produces dist/clerk of 62,388,832 B (down from 63,379,552 B)
  • bun run scripts/build.ts --target darwin-arm64 --version 0.0.0-test succeeds and the binary reports the injected version
  • bun run typecheck passes
  • bun run lint passes
  • bun run format:check passes
  • bun run test — all 82 unit + integration tests pass
  •  Manual smoke on the minified compiled binary: --version, --help, apps --help, init --help, completion bash all behave correctly
  •  CI runs bun changeset status --since=origin/main (verified locally with staged changeset: exits 0, "clerk: patch")
  •  CI runs bun run test:e2e against the source (not the compiled binary), so minify is not exercised but also not broken

📝 Walkthrough
Walkthrough
This change enables build minification across the CLI build pipeline. A changeset metadata file documents the patch release for the clerk package. The build and build:compile scripts in packages/cli-core/package.json add the --minify flag to Bun build invocations. The main build script in scripts/build.ts adds --minify to the Bun compile command for selected targets. These modifications reduce the output bundle sizes without altering functionality.
