Accepting staged files
lint-staged passes the files that you have staged in your git index, filtered by the glob in your lint-staged config, as arguments to the executable you've specified in your config. For example, if you have staged src/example.js
, test/example.js
, and readme.md
in your git index, and you have lint-staged configured to run prettier --write
for any files matching the **/*.js
glob, lint-staged will invoke prettier --write src/example.js test/example.js
. Typically, all command line arguments to dotcom-tool-kit
will be interpreted as additional hooks to be run, but any arguments after an --
escape switch will instead be parsed as file paths which are passed as arguments to all tasks associated with the specified hooks. For example, you can invoke multiple hooks by passing them all as arguments, such as dotcom-tool-kit format:staged test:staged
. lint-staged will pass any staged files as additional arguments, like dotcom-tool-kit format:staged src/index.js
, but Tool Kit will interpret src/index.js
as a hook name. Instead we want to call dotcom-tool-kit format:staged -- src/index.js
, so we include the --
argument when configuring lint-staged, and any arguments afterwards will be interpreted as file paths and passed as a files
argument to tasks. Therefore, any tasks that are expected to be used with lint-staged should be able to accept this files
string array in their run()
method so that their task can be filtered to only run over files that have been staged in git.
