Workspaces in Yarn

Projects tend to grow over time, and, occasionally, some pieces of a project can be useful elsewhere in other projects. For example, Jest, being a generic testing tool, gave birth to many packages, one of them is jest-snapshot that is now used in other projects like snapguidist and chai-jest-snapshot.
Let's Dev: A Package Manager
Posted Jul 11, 2017 by Maël Nison
Hello everyone! Today, we’re gonna write a new package manager, even better than Yarn! Ok, maybe not, but at least we’re gonna have some fun, learn how package managers work, and think about what could come next on Yarn.
Adding Command Line Aliases for Yarn
Posted Jun 19, 2017 by G. Kay Lee
One of the core design philosophies of Yarn is to strive for simpleness; a lean CLI without redundant features. That’s why Yarn has resisted adding random built-in shorthands like
npm r or an aliases system like the one you can find in Git. We believe that the benefits they could possibly bring to the Yarn experience are not justified by the cost required to build and maintain such a full-fledged subsystem.

One of the claims that Yarn makes is that it makes your package management “deterministic”. But what exactly does this mean? This blog post highlights how both Yarn and npm 5 are deterministic, but differ in the exact guarantees they provide and the tradeoffs they have chosen.

Cloudflare security incident and impact on Yarn users
Posted Feb 24, 2017 by Sebastian McKenzie
Yarn uses its own proxy to the npm registry in order to allow us to experiment with the way the Yarn client works and allow optimizations in the future around how packages are resolved. This registry is used by all Yarn users by default.
Lockfiles should be committed on all projects

Yarn is a new package manager that we built to be consistent and reliable. When installing hundreds or even thousands of third-party packages from the internet you want to be sure that you’re executing the same code across every system.

We’re pleased to announce the open source release of Yarn, a collaboration between Facebook, Exponent, Google, and Tilde. With Yarn, engineers still have access to the npm registry, but can install packages more quickly and manage dependencies consistently across machines or in secure offline environments. Yarn enables engineers to move faster and with confidence when using shared code so they can focus on what matters — building new products and features.
