flat-yarn-install

Run yarn --install --flat in current working directory, and parse it's output.

Usage:

flat-yarn-install --newest
flat-yarn-install /path/to/auto-response-script.js

Content of auto response script: (Note: typescript and esm are not supported, just a hint here!)

export default async function resolve(packageName: string, versions: string[]) {
	return versions[0]; // select first option
}

For example:

info Unable to find a suitable version for "supports-color", please choose one by typing one of the numbers below:
    1) "supports-color@^4.5.0" which resolved to "4.5.0"
    2) "supports-color@^5.3.0" which resolved to "5.5.0"
    3) "supports-color@^6.1.0" which resolved to "6.1.0"

Will call:

const result = await resolve('supports-color', ["4.5.0", "5.5.0", "6.1.0"]);

If result is "5.5.0", 2\n will send to yarn's stdin.

Note

Resolve result will save to resolutions field inside package.json.
You MUST delete it before you update some dependency's version, or before you want to chose a different version.

If some package is already exists in resolutions, it will not overwrite by this process. (but "some/sub-dep" is not supported)
