mix fude.build (Fude v0.1.0)

Builds the Fude charts into priv/static.

$ mix fude.build

This task is for work on Fude itself. An application that uses Fude gets the built files in the Hex package and does not run this task: in any project but Fude, the task stops with an error before it changes a file.

The task:

  1. Runs npm ci in assets/ when assets/node_modules is missing or assets/package-lock.json changed since the last install.
  2. Empties priv/static, so that it holds only the files of this build.
  3. Runs esbuild (the esbuild Mix package) with the :fude_esm and :fude_cjs profiles.
  4. Copies assets/css/fude.css and assets/css/fude-sumi.css to priv/static/, and the maps of assets/maps/ to priv/static/maps/.

After the task, priv/static holds exactly these files, which are the files of the Hex package.

It needs npm on the path and the :esbuild dependency, which is available in the :dev environment.
