@atlaskit/codemod-cli v0.24.0

Codemods

To easily download and run codemods associated with atlassian-frontend components and services, we provide a CLI tool called @atlaskit/codemod-cli.

The idea is that upgrading major versions can be assisted by codemods, reducing upgrade-pain, improving adoption and giving component authors the flexibility to improve API and component design.

Note: Codemods will be designed to do the heavy lifting, but they'll often not be perfect so some manual work may still be required in order to successfully migrate.

Usage

$ npx @atlaskit/codemod-cli /project/src/file.js

Options

--preset, -n

Select which transform to run from existing transform list by providing the preset name. This will allow you run the transfrom without any interaction.

example:

• npx @atlaskit/codemod-cli -n theme-to-design-tokens --extensions tsx,ts,js --parser tsx /project/src

--transform, -t

The transform to run, transforms can be either a single file or directory with an index.

example:

• npx @atlaskit/codemod-cli --transform codemods/my-special-mod /project/src/file.js
• npx @atlaskit/codemod-cli --transform codemods/my-special-mod/index.ts /project/src/file.js

--since-ref

Determines changed packages since the specified git ref and runs all codemods for them. The automatic version of --packages. The ref can be any valid git ref, e.g. a commit hash, HEAD etc.

example:

• npx @atlaskit/codemod-cli --since-ref HEAD /project/src
• npx @atlaskit/codemod-cli --since-ref abcdef123 /project/src

--packages

Runs transforms for the specified comma separated list of packages, optionally include a version for each package to run all transforms since that version

example:

• npx @atlaskit/codemod-cli --packages @atlaskit/button /project/src
• npx @atlaskit/codemod-cli --packages @atlaskit/button@3.0.0,@atlaskit/range@4.0.0 /project/src

--parser, -p

Parser to use for parsing the source files you are code modding.

options:

• babel (default)
• babylon
• flow
• ts
• tsx

example:

• npx @atlaskit/codemod-cli --parser tsx /project/src/file.js
• npx @atlaskit/codemod-cli -p babel /project/src/file.js

--extensions, -e

Transform files with these file extensions (comma separated list) (default: js)

example:

• npx @atlaskit/codemod-cli --extensions ts,tsx /project/src/file.js
• npx @atlaskit/codemod-cli -e js /project/src/file.js

--ignore-pattern

Ignore files that match a provided glob expression

example:

• @atlaskit/codemod-cli --ignore-pattern node_modules /project/src/file.js

--no-filter-paths

The codemod CLI filters supplied file paths by default, improving runtime by preventing codemods from running in non-dependent packages. Add this flag if there are problems with the filtering logic.

example:

• npx @atlaskit/codemod-cli --no-filter-paths ./packages

--version, -v

Get current version number

example:

• @atlaskit/codemod-cli --version
• @atlaskit/codemod-cli -v

--help

Print all help text to the command line

example:

• @atlaskit/codemod-cli --help

Custom options

All options are passed to the transformer, which means you can supply custom options that are not listed here.

examples:

• npx @atlaskit/codemod-cli --foo bar /project/src/file.js

Testing locally

When wanting to run the CLI before it has been published you can run the start command.

yarn start [commands]

For a list of commands run it with -h or refer to the documentation above.
