🍣 A Rollup plugin which Converts YAML files to ES6 modules.
This plugin requires an LTS Node version (v8.0.0+) and Rollup v1.20.0+.
Using npm:
npm install @rollup/plugin-yaml --save-devCreate a rollup.config.js configuration file and import the plugin:
import yaml from '@rollup/plugin-yaml';
export default {
input: 'src/index.js',
output: {
dir: 'output',
format: 'cjs'
},
plugins: [yaml()]
};Then call rollup either via the CLI or the API.
With an accompanying file src/index.js, the local heroes.yaml file would now be importable as seen below:
// src/index.js
import { batman } from './heroes.yaml';
console.log(`na na na na ${batman}`);Type: String
Default: single
If single, specifies that the target YAML documents contain only one document in the target file(s). If more than one document stream exists in the target YAML file(s), set documentMode: 'multi'.
Type: String | Array[...String]
Default: null
A minimatch pattern, or array of patterns, which specifies the files in the build the plugin should ignore. By default no files are ignored.
Type: String | Array[...String]
Default: null
A minimatch pattern, or array of patterns, which specifies the files in the build the plugin should operate on. By default all files are targeted.
Type: Boolean
Default: true
If true, specifies that the data in the target YAML file(s) contain trusted data and should be loaded normally. If false, data is assumed to be untrusted and will be loaded using safety methods.
Type: Function
Default: undefined
A function which can optionally mutate parsed YAML. The function should return the mutated object, or undefined which will make no changes to the parsed YAML.
yaml({
transform(data) {
if (Array.isArray(data)) {
return data.filter(character => !character.batman);
}
}
});
