This package has moved and is now available at @rollup/pluginutils. Please update your dependencies. This repository is no longer maintained.

rollup-pluginutils

A set of functions commonly used by Rollup plugins.

Installation

1npm install --save rollup-pluginutils

Usage

addExtension

1import { addExtension } from 'rollup-pluginutils';
2
3export default function myPlugin ( options = {} ) {
4  return {
5    resolveId ( code, id ) {
6      // only adds an extension if there isn't one already
7      id = addExtension( id ); // `foo` -> `foo.js`, `foo.js -> foo.js`
8      id = addExtension( id, '.myext' ); // `foo` -> `foo.myext`, `foo.js -> `foo.js`
9    }
10  };
11}

attachScopes

This function attaches Scope objects to the relevant nodes of an AST. Each Scope object has a scope.contains(name) method that returns true if a given name is defined in the current scope or a parent scope.

See rollup-plugin-inject or rollup-plugin-commonjs for an example of usage.

1import { attachScopes } from 'rollup-pluginutils';
2import { walk } from 'estree-walker';
3
4export default function myPlugin ( options = {} ) {
5  return {
6    transform ( code ) {
7      const ast = this.parse( code );
8
9      let scope = attachScopes( ast, 'scope' );
10
11      walk( ast, {
12        enter ( node ) {
13          if ( node.scope ) scope = node.scope;
14
15          if ( !scope.contains( 'foo' ) ) {
16            // `foo` is not defined, so if we encounter it,
17            // we assume it's a global
18          }
19        },
20        leave ( node ) {
21          if ( node.scope ) scope = scope.parent;
22        }
23      });
24    }
25  };
26}

createFilter

1import { createFilter } from 'rollup-pluginutils';
2
3export default function myPlugin ( options = {} ) {
4  // `options.include` and `options.exclude` can each be a minimatch
5  // pattern, or an array of minimatch patterns, relative to process.cwd()
6  var filter = createFilter( options.include, options.exclude );
7
8  return {
9    transform ( code, id ) {
10      // if `options.include` is omitted or has zero length, filter
11      // will return `true` by default. Otherwise, an ID must match
12      // one or more of the minimatch patterns, and must not match
13      // any of the `options.exclude` patterns.
14      if ( !filter( id ) ) return;
15
16      // proceed with the transformation...
17    }
18  };
19}

If you want to resolve the patterns against a directory other than process.cwd(), you can additionally pass a resolve option:

1var filter = createFilter( options.include, options.exclude, {resolve: '/my/base/dir'} )

If resolve is a string, then this value will be used as the base directory. Relative paths will be resolved against process.cwd() first. If resolve is false, then the patterns will not be resolved against any directory. This can be useful if you want to create a filter for virtual module names.

makeLegalIdentifier

1import { makeLegalIdentifier } from 'rollup-pluginutils';
2
3makeLegalIdentifier( 'foo-bar' ); // 'foo_bar'
4makeLegalIdentifier( 'typeof' ); // '_typeof'

dataToEsm

Helper for treeshakable data imports

1import { dataToEsm } from 'rollup-pluginutils';
2
3const esModuleSource = dataToEsm({
4  custom: 'data',
5  to: ['treeshake']
6}, {
7  compact: false,
8  indent: '\t',
9  preferConst: false,
10  objectShorthand: false,
11  namedExports: true
12});
13/*
14Outputs the string ES module source:
15  export const custom = 'data';
16  export const to = ['treeshake'];
17  export default { custom, to };
18*/

extractAssignedNames

Extract the names of all assignment targets from patterns.

1import { extractAssignedNames } from 'rollup-pluginutils';
2import { walk } from 'estree-walker';
3
4export default function myPlugin ( options = {} ) {
5  return {
6    transform ( code ) {
7      const ast = this.parse( code );
8
9      walk( ast, {
10        enter ( node ) {
11          if ( node.type === 'VariableDeclarator' ) {
12          	const declaredNames = extractAssignedNames(node.id);
13          	// do something with the declared names
14          	// e.g. for `const {x, y: z} = ... => declaredNames = ['x', 'z']
15          }
16        }
17      });
18    }
19  };
