Configuration reference
These options control how Chromatic behaves via the CLI, config file and the GitHub Action. Refer to branching docs and diagnosing CLI issues for more context on when to use some of these flags.
Note that the config file only supports a subset of these options. Some options are exclusive to the CLI or the config file. The next section tags each option with the appropriate context.
Glob Types: Where supported, globs are handled via picomatch. To learn more about globs and how to use them, refer to our guide on globs. To verify your glob pattern, use the picomatch-playground.
