While compiling my TypeScript project with the provided configuration, I encountered an error message stating: "Error: When building multiple chunks, the output.dir option must be used, not output.file."
Any assistance would be greatly appreciated. Thank you.
// [EDIT: I've made adjustments to simplify this configuration]
// rollup.config.js
import resolve from 'rollup-plugin-node-resolve'
import commonjs from 'rollup-plugin-commonjs'
import typescript from 'rollup-plugin-typescript2'
import { uglify } from 'rollup-plugin-uglify'
import gzip from 'rollup-plugin-gzip'
export default {
input: 'src/main/my-project.ts',
output: {
file: 'dist/my-project.umd.production.js',
format: 'umd',
name: 'MyProject',
sourcemap: false,
globals: {
'react': 'React'
}
},
external: ['react'],
plugins: [
resolve(),
commonjs(),
typescript({
exclude: 'node_modules/**'
}),
uglify(),
gzip()
]
}
This is my tsconfig.json file in case it might factor in. The build script begins with rollup --c rollup.config.js:
