How to avoid install of packages in monorepo using Yarn

I built a monorepo using Lerna and Yarn workspaces.

Everything works fine but everytime I install a new dependency on a package (let's call him A) using:

yarn add <package_name>

Yarn adds it and then triggers the install script of all the packages in the monorepo, even the ones that A doesn't rely on.

It there anyway to avoid this? It takes a few moment to install them for no reason at all.

Using scope add the package to the particular module.

lerna add some_package_1 --scope=some_module_x

You can try Yarn 2 with nodeLinker: node-modules in .yarnrc.yml. Yarn 2 guarantees to trigger rebuild only on packages that have their dependencies changed, this is something that was not guaranteed by Yarn 1. However there will still be a very rare case when seemingly unrelated packages be rebuilt if they are hoisted differently after adding new package, but this will happen very rarely.

Try adding to the specific workspace with:-

yarn workspace <workspace_name> add <package_name>
