--target @next for specific packages

[zaaakher]

Hi,

Thank you @raineorshine for this wonderful package.

I use the config .ncurc.json to reject certain packages from being updated. And I was wondering if there's a way I can dictate a specific target tag for certain packages in particular?

So my team have a package @sikka/hawa and we're always using it in the @next tag so we're always testing the latest. We always have that package like this for example

dependencies: {
    "@sikka/hawa": "0.34.0-next"
}

But when I run the ncu command it sometimes updates @sikka/hawa to the latest release like:

dependencies: {
    "@sikka/hawa": "0.33.0"
}

And I have a feeling if I use the flag --target @next when I run ncu then I might also update other dependencies to their @next tag.

Suggestion

I'm thinking maybe the .ncurc config file can take an option like this maybe? 👇

{
  "reject": ["react-router-dom", "styled-components"],
  "target": [
    {
      "name": "@sikka/hawa",
      "tag": "next"
    },
    {
      "name": "other-package",
      "tag": "beta"
    }
  ]
}

I was looking at src/lib/getNcuRc.ts and from my understanding so far I think the keys in the config file are the same as the cli flags. So maybe it's already implemented I just have to use the "target" key in the config file properly.

Hi. Yes, this is currently supported in the .ncurc.js config. You can define a target function like this:

module.exports = {
  target: name => name === '@sikka/hawa' ? '@next' : 'latest'
}

Yup that's exactly what I'm looking for. Much appreciated, Thanks @raineorshine 🌹
