# ESLint Scope
|
|
|
|
ESLint Scope is the [ECMAScript](http://www.ecma-international.org/publications/standards/Ecma-262.htm) scope analyzer used in ESLint. It is a fork of [escope](http://github.com/estools/escope).
|
|
|
|
## Install
|
|
|
|
```
|
|
npm i eslint-scope --save
|
|
```
|
|
|
|
## 📖 Usage
|
|
|
|
To use in an ESM file:
|
|
|
|
```js
|
|
import * as eslintScope from 'eslint-scope';
|
|
```
|
|
|
|
To use in a CommonJS file:
|
|
|
|
```js
|
|
const eslintScope = require('eslint-scope');
|
|
```
|
|
|
|
Example:
|
|
|
|
```js
|
|
import * as eslintScope from 'eslint-scope';
|
|
import * as espree from 'espree';
|
|
import estraverse from 'estraverse';
|
|
|
|
const ast = espree.parse(code, { range: true });
|
|
const scopeManager = eslintScope.analyze(ast);
|
|
|
|
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
|
|
}
|
|
});
|
|
```
