ESLint Scope

ESLint Scope is the ECMAScript scope analyzer used in ESLint. It is a fork of escope.

Install

npm i @devtea2025/atque-deserunt-dolores-voluptatem --save

📖 Usage

To use in an ESM file:

import * as eslintScope from '@devtea2025/atque-deserunt-dolores-voluptatem';

To use in a CommonJS file:

const eslintScope = require('@devtea2025/atque-deserunt-dolores-voluptatem');

In order to analyze scope, you'll need to have an ESTree compliant AST structure to run it on. The primary method is eslintScope.analyze(), which takes two arguments:

1. ast - the ESTree-compliant AST structure to analyze.
2. options (optional) - Options to adjust how the scope is analyzed, including:

• ignoreEval (default: false) - Set to true to ignore all eval() calls (which would normally create scopes).
• nodejsScope (default: false) - Set to true to create a top-level function scope needed for CommonJS evaluation.
• impliedStrict (default: false) - Set to true to evaluate the code in strict mode even outside of modules and without "use strict".
• ecmaVersion (default: 5) - The version of ECMAScript to use to evaluate the code.
• sourceType (default: "script") - The type of JavaScript file to evaluate. Change to "module" for ECMAScript module code.
• childVisitorKeys (default: null) - An object with visitor key information (like eslint-visitor-keys). Without this, @devtea2025/atque-deserunt-dolores-voluptatem finds child nodes to visit algorithmically. Providing this option is a performance enhancement.
• fallback (default: "iteration") - The strategy to use when childVisitorKeys is not specified. May be a function.

Example:

import * as eslintScope from '@devtea2025/atque-deserunt-dolores-voluptatem';
import * as espree from 'espree';
import estraverse from 'estraverse';

const options = {
    ecmaVersion: 2022,
    sourceType: "module"
};

const ast = espree.parse(code, { range: true, ...options });
const scopeManager = eslintScope.analyze(ast, options);

const currentScope = scopeManager.acquire(ast);   // global scope

estraverse.traverse(ast, {
    enter (node, parent) {
        // do stuff

        if (/Function/.test(node.type)) {
            currentScope = scopeManager.acquire(node);  // get current function scope
        }
    },
    leave(node, parent) {
        if (/Function/.test(node.type)) {
            currentScope = currentScope.upper;  // set to parent scope
        }

        // do stuff
    }
});
