CLI
Get started with using the Codemod command-line interface.
The Codemod command-line interface (CLI) allows you to interact with Codemod platform using a terminal or through an automated system.
The Codemod CLI accepts a variety of subcommands and options to explore, publish, and run codemods.
Installation
npm i -g codemod
List available codemods
The command can be used to list the codemods available in the Codemod Registry and optionally search for a specific codemod using its name or tags.
codemod list [optional search query]
Running codemods
You can use the codemod
command to run codemods.
This command uses the following format:
codemod [codemod name]
When using the codemod
command, Codemod CLI will attempt to run a codemod as long as it is not followed by a reserved command name.
Available options:
The following options can be used to change the default behavior of the Codemod CLI.
Can be used to specify the files to be targeted by the codemod.
codemod [codemod name] -i "[glob pattern]"
While running a codemod, you may want to prevent changes from occurring to specific parts of your project. The --exclude
option can be used to specify a glob pattern of the files to be ignored by the codemod.
codemod [codemod name] -e "[glob pattern]"
Can be used to specify the directory of your project that the CLI should target while running codemods. This option is set as the current directory by default.
codemod [codemod name] -t [path]
Can be used to specify the path to the codemod package folder stored locally that you want to run using the Codemod CLI.
codemod -s [path]
Can be used to disable prettier formatting to the files affected by the codemod.
codemod [codemod name] --raw

codemod [codemod name] --no-cache
Can be used to disable dependencies installation after codemod run.
codemod [codemod name] --skip-install

codemod [codemod name] --json
Can be used to specify the number of worker threads the CLI uses while running codemods.
codemod [codemod name] -n [number of threads]
