buddy ts build

buddy ts build <type> runs tsc -p tsconfig.<type>.json in the current directory. For cjs and tslib it then copies package.cjs.json to <type>/package.json.

Usage

buddy ts build <type>

Requires the plugin to be enabled.

Arguments

Argument	Type	Default	Effect
`type`	`cjs`, `esm`, or `tslib`	required	Picks the tsconfig file `tsconfig.<type>.json` and, for `cjs` and `tslib`, the output folder `<type>/` that receives `package.json`.

The command has no flags.

Output

On success it prints:

building cjs...
copying package.json...
build cjs done

For esm, the copying package.json... line is absent.

Exit codes

Code	When
`0`	`tsc` succeeded and, for `cjs` and `tslib`, the copy succeeded.
`1`	`tsc` failed (the error, with `tsc`’s output, is printed as an uncaught `ExecaError`), or the output folder does not exist for the copy.
`2`	`type` is missing (`missing required argument <type>`) or is not one of the three values (`invalid value for argument <type>`).

Behavior

It runs tsc from PATH, not from a resolved TypeScript install. Package scripts, pnpm exec, and npx put the project’s node_modules/.bin on PATH.
tsc output is captured. On success none of it is printed.
It copies to ./<type>/package.json relative to the current directory. Set the tsconfig’s outDir to cjs or tslib so the copy lands next to the emitted files. With another outDir, tsc emits there and the copy then fails with ENOENT (exit code 1) because <type>/ does not exist.
It overwrites an existing <type>/package.json.
esm only runs tsc. It writes no package.json.
tslib is a name only. The command does not add importHelpers. Set it in tsconfig.tslib.json.

Examples

testcases/build-ts in this repository builds both CommonJS variants with these scripts:

{
  "scripts": {
    "test:cjs": "buddy ts build cjs",
    "test:tslib": "buddy ts build tslib"
  }
}

{
  "extends": ["./tsconfig.json", "@repobuddy/typescript/tsconfig/modules/buddy-commonjs.json"],
  "compilerOptions": {
    "outDir": "cjs"
  }
}

{
  "extends": "./tsconfig.cjs.json",
  "compilerOptions": {
    "importHelpers": true,
    "outDir": "tslib"
  }
}

After buddy ts build cjs, cjs/ holds index.js, index.js.map, index.d.ts, index.d.ts.map, and a package.json with { "type": "commonjs" }.

Building esm without a tsconfig.esm.json exits with code 1:

building esm...
ExecaError: Command failed with exit code 1: tsc -p tsconfig.esm.json

error TS5058: The specified path does not exist: '<cwd>/tsconfig.esm.json'.
