Grasp is a command-line utility for structural search, replace, and refactoring of JavaScript code based on its abstract syntax tree rather than text. It supports CSS-style selector queries (squery) and example-based queries with wildcards (equery), and can also be used as a library.

Use cases

• find all usages of a variable in javascript code
• refactor javascript code structurally instead of with grep and sed
• search javascript ast with css-like selectors
• replace function call arguments across a codebase
• find if statements with compound conditions
• run codemods on javascript files from the command line

When to choose

• you need structure-aware search or replacement in JavaScript that ignores formatting differences
• you want to write quick one-line codemods or macros from the terminal
• you prefer CSS-style selectors or code examples with wildcards over regex

When to avoid

• you need to refactor languages other than JavaScript
• you want an actively maintained tool with modern ES2020+ support
• you need IDE-integrated refactoring rather than a CLI
