Move from Lerna to alternative toolset (like Nx)

Have you read the Contributing Guidelines on issues?

• I have read the Contributing Guidelines on issues.

Motivation

Lerna is not maintained anymore. As a result, you may want to switch to an alternative solution (such as Nx).

Self-service

• I'd be willing to do some initial work on this proposal myself.

Agree 👍 I've also talked to @slorber about this on Discord. My main candidate for now is monodeploy, because we are also migrating to Yarn v3 in #6028. cc @RDIL in case you want to make the DX fully prepared in that PR. The publishing process needs investigation.

We'll see if Nx is necessary after we've made the migration to Yarn v3.

We also have good feedback about using Turborepo from @yangshun

Please don't submit any PR on this for now, we'll figure out the setup we want to adopt

For the time being, our Lerna setup still works

[Josh-Cena]

For me, the choice is either monodeploy (works best with Yarn v3 workspaces), or Nx (I work on several other projects that use it with great success). I'm open to try Turborepo, but I'll need some comparisons.

If we move to Vercel hosting then using Turborepo would be a no-brainer.

[Josh-Cena]

Does Vercel hosting offer special integration with TR? If that, I'm very interested in seeing a working example 😄

[yangshun]

Yes, they have remote caching, but I'm not sure whether it's free or a paid feature.

[Josh-Cena]

A great amount of our CI time (in PR) is spent on building packages. If we can cut that down (through persisting some cache), we can greatly speed up the deploy preview. Looking forward to any solution.

[slorber]

Afaik Meta is already using Vercel for many sites (like the new Beta site) and maybe not using Nx cloud already.

I'd rather ask @zpao what is possible for us to use there before choosing the definitive tool.

Having caching would be very nice for sure.

Lerna still works and is not maintained again, so there's no need to hurry

Lerna 5.0 has just been released, with a lot of dependency upgrades! This makes me hate it a lot less.

Lerna 5.0 has just been released, with a lot of dependency upgrades! This makes me hate it a lot less.

It seems Lerna 5.1.x is way faster than TR (5.3 times). Quoting Victor tweet

🎉 Lerna now supports:

• distributed caching
• tasks pipelines (e.g., tests can depend on builds)
• distributed task execution

It's super fast 🚀

➡️ Lerna is 5.3 times faster than Turborepo!

I'm not even sure if we need to do anything at this stage, since I don't know if it's Lerna or tsc being slow, but I'd still like to play with different managers just to confirm. I'd definitely try out 5.1 in this weekend's dependency upgrade.

@Josh-Cena usually the performance boils down to:

• TypeScript's type checking portion is always on, and the more types it finds (so essentially every type def in node modules), the slower it is.
• Lerna is mostly just Git subprocess operations or startup, both of which are a bit slow.
