Unmonorepo

The problem

Monorepo is great, but when it comes to serverless, the node_modules directory needs to be as small as possible, and there should be no soft links.

It is difficult/impossible for the usual package managers to separately install condensed node_modules for a given package.json (--production)

A simple version of solution

What unmonorepo does is relatively simple: install the specified package.json in the user cache directory, and then copy the resulting node_modules to the specified location.

Usage

npm i -g unmonorepo
# or
yarn global add unmonorepo

Then just run

# all parameters are optional, see unmonorepo --help
unmonorepo --source=./package.json --dist=./dist/node_modules --command="npm install --omit=dev --prefer-offline"

Unmonorepo will grab dependencies in ./package.json and run npm install --omit=dev --prefer-offline to install all dependencies, then copy node_modules to ./dist/node_modules

Note

Source package.json dependencies should not contain any workspace (monorepo modules), you should use webpack (or other javascript bundler) to pack your source code, or just use a script to process workspace dependency files.
