Workspaces are stable enough to be used in large-scale applications and shouldn’t change anything from the way the regular installs work, but if you think they’re breaking something, you can disable them by adding the following line into your Yarnrc file: Since it might be tedious to keep track of each of them, this field also accepts glob patterns! For example, Babel reference all of their packages through a single packages/* directive. The workspaces field is an array containing the paths to each workspace. They will never try to support the high-level feature that Lerna offers, but by implementing the core logic of the resolution and linking steps inside Yarn itself we hope to enable new usages and improve performance. Yarn’s workspaces are the low-level primitives that tools like Lerna can (and do!) use. node_modules/pkg-a -> /workspace-a and you will be able to import code from /workspace-a with const pkgA = require("pkg-a") (or maybe import pkgA from "pkg-a" ). This means that if the /workspace-a/package.json name field was "pkg-a", the alias will be the following: You also need to know that the /workspace-a/package.json#name field is used and not the folder name. That’s the trick that allows you to require the package as if it was a normal one! Please note the fact that /workspace-a is aliased as /node_modules/workspace-a via a symlink. It won’t be there unless some other package use it as a dependency.Īnd that’s it! Requiring workspace-a from a file located in workspace-b will now use the exact code currently located inside your project rather than what is published on npm, and the cross-env package has been correctly deduped and put at the root of your project to be used by both workspace-a and workspace-b. Note: don’t look for /node_modules/workspace-b. node_modules/workspace-a -> /workspace-a You decide all YAML and Markdown files in all your dependencies installed in node_modules can be safely deleted. If you discover the autoclean process is deleting files that are needed for a package to work properly, then you should remove theĬorresponding entry from the. yarnclean and customize them to fit your needs. It is highly recommended that you manually review the default entries in. It is impossible to predict all directories and files thatĪre actually unnecessary for all existing and future NPM packages, so this default list may cause a package to no longer work. This default list is a guess at what is likely not needed. yarnclean file, it will be pre-populated with a set of default itemsįor deletion. When the yarn autoclean -init command is used to create a. ![]() yarnclean file exists, run the clean process. If the file already exists, it will not be overwritten. This file should then be reviewed and edited to customize which files will be cleaned. ![]() yarnclean file if it does not exist, and adds the default entries. ![]() yarnclean file and using each as a glob pattern of files to delete. The clean is performed by reading each line of the. yarnclean file exists in a package, autoclean functionality will be enabled. yarnclean file should be added to version control. yarnclean file, or run yarn autoclean -init to create the file with default entries. It will permanently delete files in node_modules which could cause packages to stop working.Īutoclean functionality is disabled by default. Unless you are experiencing issues with the amount of files that are installed as part of node_modules it is not recommended to use this command. Note: This command is considered for advanced use cases only. It reduces the number of files in your project’s node_modules folder which is useful in an environment where packages are checked into version control directly. The autoclean command frees up space by removing unnecessary files and folders from dependencies. Cleans and removes unnecessary files from package dependencies.
