## npx Flags & Config

- There are currently 4 npx flags:
  - `-n` Specify name(s) of codemod(s) to run. You can find these names in `codemods/src/codemods/mods`. Make sure that they are `enabled` before running them, or else they won't run!
  - `-r` Specify regex pattern(s) to identify mod(s) to run.
  - `-e` Boolean flag that flips the inclusion of the specify mods. Use this flag with the selective flags `-n` or `-r` to opt to _exclude_ the selected mods rather than include them.
  - `-c` For developers who don't want to worry about the command line, they can create a `modConfig.json` file in their repo. The template for the file looks like this, where `stringFilters` and `regexFilters` would correspond to inputs following `-n` and `-c`, respectively: 
  ```jsonld=
  {
  "stringFilters": [],
  "regexFilters": [],
  "includeMods": true
  }
  ```
 - If you specify no flags, npx will run all `enabled` codeods.
