I'm having a really weird issue where my .mjs files gets renamed to .js after tsup finishes building.
My tsup.config.ts:
import { defineConfig, type Options } from "tsup";
export default defineConfig((options: Options) => ({
clean: true,
format: ["esm"],
...options,
}));It goes like this:
$ tsup --onSuccess "ls dist" src # This will list files in dist/ after building
CLI Building entry: src/index.ts
CLI Using tsconfig: tsconfig.json
CLI tsup v8.0.2
CLI Using tsup config: ...
CLI Target: es2022
CLI Cleaning output folder
ESM Build start
ESM dist/index.mjs 743.75 KB
ESM ⚡️ Build success in 46ms
index.mjs # <-- Note the .mjs extension
$ ls dist
index.jsThe file is mysteriously renamed. So when you do:
$ tsup --onSuccess "node dist/index.mjs" srcIt will fail because the file is no longer there. node dist/index.js doesn't work either, so I suspect there is a small window where the file just doesn't exist. Does anyone know why this is happening?
