Support for Object Rest/Spread Properties proposal in Acorn 5 - a tiny, fast JavaScript parser, written completely in JavaScript.
You can use module directly in order to get Acorn instance with plugin installed:
var acorn = require('acorn-object-rest-spread');
Or you can use inject.js
to inject multiple plugins into Acorn:
var acorn = require('acorn')
var injectAcornJsx = require('acorn-jsx/inject');
var injectAcornObjectRestSpread = require('acorn-object-rest-spread/inject');
injectAcornJsx(acorn);
injectAcornObjectRestSpread(acorn);
Then, use the plugins
option whenever you need to support Object Rest/Spread while parsing:
var ast = acorn.parse(code, {
plugins: {objectRestSpread: true}
});
