mrex

mrex is short for monorepo exec

Run package scripts for every package in a monorepo that uses workspaces, with respect to the order of inclusion.

Motivation

Assume a monorepo with a structure like this:

some-monorepo
-- packages
---- packageA
---- packageB
---- packageC

where

• packageA depends on packageB and packageC,
• packageB depends on packageC

Then the correct order for running, let's say, a build command, would be

• packageC
• packageB
• packageA

But older yarn versions don't account for dependencies between packages in a workspace. This package was created to solve this problem.

Installation

npm i -D mrex

or

yarn add -D mrex

or

pnpm i -D mrex

Usage:

npm run mrex <command>

or

yarn mrex <command>

or

pnpm mrex <command>

For example:

yarn mrex build

Runs a build script in every package, in correct order.

mrex will detect npm, yarn or pnpm workspaces and run the command with the proper package manager.
