⚙️ Config

mostir uses a mostir.config.mjs file at the project root.

Options​

  • build (required)
    Any esbuild options.

    • Common keys: entryPoints, outdir, platform, format, target, etc.

  • ignore (optional)
    Glob patterns to exclude.
    Applies to:

    • build (when entryPoints is a glob string)
    • sync (non-TS file mirroring & folder sync)
    • diff / hash (future roadmap)

Example Config​

// mostir.config.mjs
const ignore = [
  "**/*.test.ts",
  "**/__tests__/**",
  "**/*.d.ts",
];

export default {
  build: {
    entryPoints: "src/**/*.ts",
    outdir: "dist",
    platform: "node",
    format: "esm",
    target: "es2022",
    bundle: false,
    external: ["fs", "path"],
    sourcemap: true,
    minify: false,
    logLevel: "info",
    outbase: "src",
    metafile: true,
  },
  ignore,
};

Example Type​

import type { BuildOptions } from "esbuild";

export interface MostirConfig {
  build: BuildOptions;
  ignore?: string[];
}

Notes / Common pitfalls​

  • export default is required in mostir.config.mjs.
  • outfile and entryPoints (glob) cannot be used together.
  • --sync / --clean are not supported when using outfile.
