Parcel v2 + microbundle, same project, two different build.

[nkint]

Hi!

I have project for a React component and I'd like to have two builds: one for a website/demo/doc that show the component, one for the component itself as a library.

The react component is in src and the doc page is in src-doc.

The project is written in typescript, and to bundle it I'm using the rollup powered utility called microbundle and a ts definition bundler called dts-bundle-generator.

So that I have this package.json (I omitted unnecessary fields):

{
	"scripts": {
		"build-doc": "parcel build src-doc/index.html ",
		"build-lib": "microbundle --no-compress && dts-bundle-generator ./src/index.ts",
		"start": "parcel src-doc/index.html",
	},
	"source": "src/index.ts",
	"main": "build/index.js",
	"types": "build/src/index.d.ts",
}

The fields source, main and types in the package.json are required by microbundle. If I leave them here parcel v2 says:

🚨 Build failed.
@parcel/namer-default: Target "main" declares an output file path of "build/index.js" which does not match the compiled bundle type "html".

> 27 |   "main": "build/index.js",
>    |           ^^^^^^^^^^^^^^^^ Did you mean "build/index.html"?

Right now I'm thinking of a small script that adds main and types field in the package.json just before running microbundle, and remove them after it. It is an ugly solution by the way.

Do you have any advice?

Run parcel build src-doc/index.html --target default instead to ignore these main fields in package.json

wow, really thanks for fast reply 💥⚡️, you rocks!

@mischnic

I get:

🚨 Build failed.
@parcel/core: Could not find target with name "default"

@mischnic sorry, my fault, I also need to add:

"targets": {
	"default": {}
}

to package.json, as from this doc page
