Build 🛠 and Bundle 📦 your local packages. Like Bazel and Buck but for Yarn v2 🥳

yarn.Build

yarn.BUILD is a plugin for Yarn 2. It uses your dependency graph to build just whats needed, when it's needed. You can setup a monorepo with a few backend packages, a server package, maybe a graphQL schema package, and a frontend package. And build it all, in the order it's needed. Then, only rebuild when something changes.

See the full docs at yarn.BUILD

To install:

yarn plugin import https://yarn.build/latest

Commands

build: build your package and all dependencies

bundle: bundle a package and its local dependencies, designed for containers and AWS lambda.

test: test your package and it's dependencies

Config

This isn't required but, to change any of the defaults or enable beta features add the following to .yarnbuildrc.yml in the root of your yarn workspace (next to yarn.lock).

folders:
  # input defaults to the whole package directory
  input: .
  # output defaults to a folder called build. This can be set individually in package.json (see below)
  output: build
enableBetaFeatures:
  # folderConfiguration defaults to true
  # setting a default input/output folder as shown above
  # and per package i/o folder in package.json as below
  # "yarn.build": {
  #   "input": "src",
  #   "output": "dist"
  # },
  folderConfiguration: true
  # To enable yarn build path/to/package
  targetedBuilds: true
# Optional: Limit the number of concurrent builds/tests that can occur at once globally. This can also be set as a command line switch.
maxConcurrency: 4
