Advanced tools
Package description
The @babel/helper-validator-identifier npm package is a utility library used by Babel to validate string identifiers according to the ECMAScript specification. It provides functions to determine if a string is a valid identifier name, which is useful when manipulating code in a way that needs to adhere to JavaScript naming conventions.
isValidIdentifier
Checks if a string is a valid ECMAScript identifier name.
const isValid = require('@babel/helper-validator-identifier').isValidIdentifier;
console.log(isValid('validName')); // true
console.log(isValid('123invalid')); // false
isIdentifierStart
Checks if a character code can start an ECMAScript identifier.
const isIdentifierStart = require('@babel/helper-validator-identifier').isIdentifierStart;
console.log(isIdentifierStart('v'.charCodeAt(0))); // true
console.log(isIdentifierStart('1'.charCodeAt(0))); // false
isIdentifierChar
Checks if a character code can be part of an ECMAScript identifier.
const isIdentifierChar = require('@babel/helper-validator-identifier').isIdentifierChar;
console.log(isIdentifierChar('n'.charCodeAt(0))); // true
console.log(isIdentifierChar('!'.charCodeAt(0))); // false
esutils is a utility box for ECMAScript language tools. It includes a keyword check similar to @babel/helper-validator-identifier, but also provides other utilities for AST manipulation and code generation.
jstransform is a simple utility for pluggable JS syntax transforms using the visitor pattern. It includes utilities for identifier validation, but it is more focused on transforming code rather than just validating identifiers.
jscodeshift is a toolkit for running codemods over multiple JavaScript or TypeScript files. It includes utilities for working with identifiers within the context of transforming code, but it is more comprehensive and is designed for writing and applying codemods.
