Steal-stache is now included in canjs


#1

canjs 5.19.0 was just released and now comes with steal-stache. This post is meant to briefly explain what this means.

If you’ve been using canjs 5 and steal-stache in the past, you might have ran into problems on occassion where updating can would result in “multiple versions of can-stache-bindings” (or other packages) errors.

After researching the problem we realized the issue was with the way package-lock.json works. Basically what happens is that can depends on exact versions of packages, but steal-stache does not. So when you update can it starts depending on a newer version of some package that what the package-lock.json has for steal-stache.

So the result is that you import .stache file and a JavaScript file that uses can, they might have loaded different dependencies.

The fix, available in 5.19.0 is to include steal-stache in canjs.

To prevent these errors from occuring in your app in the future, do the following:

npm update can
npm uninstall steal-stache

This gets you up to version 5.19.0 (or greater) of canjs, and removes the dependency on steal-stache.

Then, in your package.json, remove the following:

{
  ...
  "steal": {
    "plugins": ["steal-stache"]
  }
}

And replace it with:

{
  ...
  "steal": {
    "plugins": ["can"]
  }
}

can is a steal plugin in that it contains steal-stache.
