Server-side plugin to provide doclet args to features.
npm install @amarajs/plugin-docletServer-side plugin to provide doclets args to features.
npm install --save @amarajs/plugin-doclet
``javascript`
const Amara = require('@amarajs/core');
const AmaraPluginDoclet = require('@amarajs/plugin-doclet');
const AmaraPluginEngineServer = require('@amarajs/plugin-engine-server');
const amara = Amara([
AmaraPluginEngineServer(server),
AmaraPluginDoclet()
]);
The @amarajs/plugin-doclet middleware allows creates no new feature types; however, it does register a new doclets arg provider for use in your features. The doclets are determined by reading the file at the requested path and parsing any JSDoc-like doclets in the form:
`javascript`
/**
* @doclet QUANTIFIER value1 value2 ...
*/
Where QUANTIFIER can be ALL, NONE, or ANY (aka SOME). If not provided, the default is ALL. Values will be converted to upper-case. For example:
`javascript`
/**
* @feature feature-123 feature-456
* @role any admin power-user
*/
Would parse into the following doclets value:
`javascript`
doclets: {
feature: {
quantifier: 'ALL',
value: 'feature-123 feature-456'
},
role: {
quantifier: 'ANY',
value: 'admin power-user'
}
}
#### Example Usage
`javascript
// exclude file content where the feature isn't configured
const switches = require('.config').switches;
const isActive = (feature) => !!switches[feature];
const whitespace = /\s+/g;
const trim = (s) => s.trim();
amara.add({
type: 'transform', // from @amarajs/plugin-bundle
targets: ['GET /features/*/.js'],
args: { feature: ({doclets}) => doclets.feature },
apply: ({feature}) => (code) => {
if (!feature) return code;
let active = false;
const {value = '', quantifier = 'ALL'} = feature;
const features = value.split(whitespace).map(trim);
switch (quantifier) {
case 'NONE':
active = !features.some(isActive);
case 'ANY':
case 'SOME':
active = features.some(isActive);
case 'ALL':
active = features.every(isActive);
}
return active ? code : '';
}
});
