ex_check now runs npm test & empowers umbrellas

ex_check was under active development in last few weeks and it now comes with a bunch of new handy features:

  1. mix check now detects & runs npm test in Phoenix projects that have assets directory with package.json in it. It’s really consistent with existing Phoenix setup as now mix check will test both your back-end & front-end code just as mix phx.server compiles & watches the two for you. More info in feature request.

  2. mix check now empowers umbrella projects, in particular the experience of running tools recursively from the umbrella root, with a handful of extra benefits over the basic Mix task recursion (parallel execution, clearer presentation & more). More info in docs.

…and a bunch more additions & fixes - all listed in Changelog.


Brief reminder: ex_check provides a mix check task that allows to efficiently run all code analysis & testing tools in an Elixir project with a single command. With no configuration it catches compilation warnings, runs ExUnit, Credo & more. It’s a real convenience for all Elixir & Phoenix projects to ensure that new code is “good to go” & then to recheck it on CI in the exact same way.

Shameless plug: Check out @elixirstatus' other community project:

Credo, a new static code analysis tool that acts as a code linter, but also focusses on teaching coding practices and code consistency.
