mise as a volta sucessor

[fowl2]

More of an FYI - the volta folk are recommending mise.

edit: one thing that I would help the migration would be if the getting started guide listed 'cmd (Windows)' and 'pwsh (PowerShell 5+)' instead of 'Windows' being PowerShell.

mise could read Volta pins (package.json -> volta.<tool>) to interpret node, npm, yarn, and pnpm versions. That would surely smooth the transition a lot.

See #8143. I agree with jdx that we shouldn't maintain deprecated tool configs.

On the other hand, it isn't practical to change almost a hundred projects in my organization from volta pins to mise.toml. Let alone a dozen of old release branches per-project.

If mise doesn't read from volta pins, that means I cannot uninstall Volta unless refactoring all these projects first, which is unlikely to happen.

And if I refactored, that would mean all developers would need to uninstall Volta and install mise, which would mean a big event coordinated between multiple teams.

Important to mention that, while unmaintained, Volta still works fine and is used by many, many people.

Given the complexity of supporting it being low (#8143), I would say it pays off. It doesn't need to stay forever.

Do you know whether plugins could contribute this feature as well?

Another great feature of Volta is that its npm-based shims are project-aware. When running outside of a project, they will use the globally-installed version of the tool. When running inside of a project, they will use that project's version.

$ volta install prettier@3.2
$ prettier --version
3.2.5
$ cd ~/repos/renovate
$ pnpm install
$ pnpm exec prettier --version
3.8.1
$ prettier --version
3.8.1

With mise, the globally-installed version is always used.

[risu729]

You can achieve this by adding the following config in your mise.toml. It takes the precedence over other mise tool paths.
However, it exposes all bins in your node_modules.

[env]
_.path = ["node_modules/bin"]

[felipecrs]

I was referring to shims. I'm not a fan of shell injection, and that's one reason why I was also a fan of Volta. I was happy to learn that Mise gives you the choice of working with shims only.

[risu729]

I see, that makes sense. I think there is no way to do that while using shims without hacky solutions.

[felipecrs]

Maybe something like:

// in the shim's code

if (isNpmBasedShim() && executableExists(`node_modules/.bin/${executableName}`) {
  // exec it instead
}

[risu729]

I'm not too sure but I think it's not something mise should fix.
