Warning from npm - caniuse-lite is outdated

I’m getting the following warning when I run mix phx.server:

Browserslist: caniuse-lite is outdated.
  Please run next command
  `npm update caniuse-lite browserslist`

I tried running the command, and got no errors, but the warning didn’t go away. I also tried mix clean; mix compile, to no avail. Suggestions?

Did you run the command in the assets directory, where the npm assets live?

That warning is shown because of the defined version of “caniuse-lite” in assets/package-lock.json file.

I sended a pull-request for update the version. :slight_smile:

I have this complaining when I run the phoenix server.

iex(1)> Browserslist: caniuse-lite is outdated. Please run:
  npx browserslist@latest --update-db
  Why you should do it regularly: https://github.com/browserslist/browserslist#browsers-data-updating

so I go to the assets folder and run:
npx browserslist@latest --update-db

then it complains for this:

Need to install the following packages:
  browserslist@latest
Ok to proceed? (y) y

I want to know if it’s ok to update the npm with the phoenix v1.6.10?

I’d just leave the caniuse-lite warning alone. Doesn’t hurt anything. I am not brave enough to dig in the rabbit hole of npm.

Upgrading the Tailwind CLI version helps with this – it’s Tailwind CSS which ships with these node modules, and they tend to get outdated over time.

  1. Adjust the Tailwind config by editing config/config.exs
  2. Run mix tailwind.install to pick up the new configuration, upgrading Tailwind CLI
