donejs update

[matthewp]

It would be nice to have a mechanism to update your project to the next major/minor version of donejs. Consider you are on version 0.15 and you want to upgrade to 0.16. Currently you'd have to do something like:

before

{
  "can-ssr": "1.0.0",
  "done-autorender": "1.0.0"
}

after

{
  "can-ssr": "2.0.0",
  "done-autorender": "2.0.0"
}

You'd have to know which dependencies needed to be updated. In this example can-ssr might have a breaking change that doesn't work with done-autorender 1.0.0, so if you only updated can-ssr your app wouldn't work.

This makes upgrading to minor versions of donejs hard. The way I've done it myself is look at donejs-cli's package.json. But users don't know about that (and shouldn't).

Maybe we could have:

donejs update 0.16

Which would upgrade all of your dependencies to 0.16.

This would be a much easier upgrade path than what I've been doing:

• rename old app folder
• donejs init app-name
• copy over old app to new app.

Now that there are codemods in canjs we could have that as part of this.

Probably by default? Can't see why not.

donejs upgrade

Without codemods:

donejs upgrade --no-codemods
