Plugins

The express-check-in command has a plugin-based architecture. There are two built-in plugins, prettier and cspell. Both of these are by default enabled if the required dependency is installed (respectively the prettier and cspell-lib packages).

To do:

  • Write documentation on how to write your own plugins
  • Load 3rd party plugins automatically?
  • Provide eslint --fix plugin?

Pre-Commit Hook

You can run express-check-in as a pre-commit hook using husky.

yarn add --dev husky
yarn husky add .husky/pre-commit "yarn express-check-in --staged"

CLI Flags

--staged

Pre-commit mode. Under this flag only staged files will be formatted, and they will be re-staged after formatting.

Partially staged files will be re-staged after formatting, but the files on disk will not be updated to reflect these changes. This prevents conflicts between the unstaged changes and the changes made by express-check-in.

--pattern

Filters the files for the given micromatch pattern.
For example express-check-in --pattern "**/*.*(js|jsx)" or express-check-in --pattern "**/*.js" --pattern "**/*.jsx"

--plugin

Explicitly pass what plugins to use, e.g.

express-check-in --plugin prettier

will only use the prettier builtin plugin, even if the cspell builtin plugin could also be loaded.

--verbose

Outputs the name of each file right before it is processed. This can be useful if Prettier throws an error and you can't identify which file is causing the problem.

--bail

Prevent git commit if any files are fixed.

--check

Check that files are correctly formatted, but don't format them. This is useful on CI to verify that all changed files in the current branch were correctly formatted.

--no-resolve-config

Do not resolve prettier config when determining which files to format, just use standard set of supported file types & extensions prettier supports. This may be useful if you do not need any customization and see performance issues.

By default, express-check-in will check your prettier configuration file for any overrides you define to support formatting of additional file extensions.

Example .prettierrc file to support formatting files with .cmp or .page extensions as html.

{
    "printWidth": 120,
    "bracketSpacing": false,
    "overrides": [
        {
            "files": "*.{cmp,page}",
            "options": {"parser": "html"}
        }
    ],
}

Project

This project started as a fork of pretty-quick. Some functionality, e.g. mercurial support, is removed to make it possible to restage partially staged files. The prettier-only implementation is expanded to also support other checks, such as spell checking via cspell.
