large-monorepo VS lerna

The Nx daemon has seen significant enhancements, notably through the use of Rust to calculate file hashes behind the scenes. This improvement not only speeds up the start-up times but also optimizes performance even without the daemon, especially on CI environments where the daemon isn't used. The benchmark results at this repo showcase the remarkable speed improvements, making Nx competitive with native code solutions while maintaining the accessibility and flexibility of Node.js. Nx is still Node-first, so contributions are easier and only the most performance-critical parts of Nx are native code.

At Nx, we’ve heavily embraced Typescript from the beginning and we’ve been very happy with that decision. Nx also stands as the fastest JS monorepo tool available, demonstrating that adopting TypeScript does not necessarily compromise speed. However, we don't stop here. To push the boundaries further, we started to rewrite the most performance critical and computationally intensive parts of the Nx core in Rust.

You can see our results and the details of the benchmark - and even run the benchmarks for yourself in this repo.

Performance is at the core of what we do at Nx. Hence it isn't surprising that Nx is the fastest JS-based monorepo solution out there. We've shown that a couple of times. But every millisecond counts! As such, we decided to experiment with Rust to see whether we could further optimize our project graph creation as well as the hasher function that is used for the computation cache.

Speed - we drastically improved the speed of Nx, making it the fastest monorepo solution in the frontend space.

Up until Lerna v4, either the p-map or p-queue npm packages have been used to delegate the task scheduling. With v5.1 we introduced nx as an additional mechanism to schedule tasks. The advantage? Nx has caching built-in, which also gives Lerna caching support, making it lightning fast. A recent benchmark test resulted in Lerna being 2.5x faster than Lage and around 4x faster than Turbo (as of Oct 2022; test it out by yourself).

Nx is faster than most of the current available alternatives. See the corresponding benchmark repository

Delegating task scheduling to Nx allows to speed up any Lerna workspace in the range of 2-10 times. Check out our public benchmark which compares Lerna with other popular JS based monorepo tools.

(as always, feel free to reproduce it here)

But let's do some more real "apples-to-apples" comparison of Lerna's speed with useNx enabled. For benchmarking Nx we have set up a repo in the past which we regularly use to measure the speed of new Nx releases with other similar tools on the market such as Lage and Turborepo: https://github.com/vsavkin/large-monorepo. We now added Lerna+Nx (Lerna with useNx enabled) to that repo to measure the impact.

Open the project up in your favorite IDE. Let's take a quick look at the project organization. The project has an Angular frontend and NestJS API backend housed in a Lerna monorepo. If you are curious about how to recreate the project, check out the repo's README file. I'll include all the npx commands, CLI commands, and the manual steps used to create the project.

Lerna currently maintained by Nx team

On Netlify's enterprise tier, approximately 46% of builds are monorepos, with the majority leveraging Nx and Lerna. Recognizing this trend, Netlify has focused on enhancing the setup and deployment experiences for monorepo projects. In particular they worked on an "automatic monorepo detection" feature. When you connect your project to GitHub, Netlify automatically detects if it's part of a monorepo, reads the relevant settings, and pre-configures your project. This eliminates the need for manual setup. This feature also extends to local development via the Netlify CLI.

This is the exact problem monorepos were born to solve. Not only will a monorepo let you share UI components, you'll be able to gradually add shared application logic as well (for instance, do all of your apps have their own logic for connecting to a database? you could roll that into a shared library with a monorepo). There are a lot of tools for accomplishing this in JS, but probably the most popular is lerna, which is built on top of NX (though lots of teams roll their own monorepo in nx without lerna, which IMO is a totally valid option).

To begin, you need to prepare your environment. A few ways to build a React package include tools like Bit, Storybook, Lerna, and TSDX. However, for this tutorial, you will use a zero-configuration bundler for tiny modules called Microbundle.

If so, are you using a monorepo tool like Nx or Lerna? If not, start there and see if it solves your problem.

I mean I don't know what your monorepo looks like, but for example infernojs (actually written with typescript) uses lerna, and lerna seems simpler than typescript references

Tools for publishing, such as Lerna (when using the --conventional-commit flag), follow this convention when incrementing package versions and generating changelog files.
