The record

Purpose: jscodeshift is a toolkit for building and running codemods over multiple JavaScript or TypeScript files.
Runner: Its runner executes a supplied transform on each file and summarizes how many files were not transformed.
Recast wrapper: The toolkit wraps recast, which aims to preserve the original code style when transforming an abstract syntax tree.
CLI: The command-line interface runs codemods from a local transform file, a transform URL, or a list of paths read from standard input.
Parsers: The CLI lists babel, babylon, flow, ts, and tsx as parser options, with babel as the default.
Parallel processing: The CLI can start up to a specified number of child processes to process source files.
Dry run: The CLI's dry-run option previews the effect of a codemod without changing files.
File selection: The CLI supports selecting file extensions and excluding files with ignore patterns or configuration files.
Code transformations: The API provides methods to find, filter, replace, insert, remove, and rename syntax-tree nodes.
Formatting: The API can convert a transformed syntax tree back to source code with optional formatting settings.
Testing: The project includes utilities for unit testing transforms with Jest or Jasmine using fixture-based or inline tests.
Editor integration: The project README links instructions for configuring VS Code to debug codemods.
Distribution: The documentation directs users to install jscodeshift from npm with `npm install -g jscodeshift`.
License: The GitHub repository lists an MIT license.
