Acorn preloaded with plugins for syntax parity with recent Node versions.
It also includes versions of the plugins compiled with Bublé, so they can be run on old Node versions (0.6 and up).
npm install acorn-node
var acorn = require('acorn-node')
The API is the same as acorn, but the following syntax features are enabled by default:
- Dynamic
import()
(via acorn-dynamic-import) - The
import.meta
property (via acorn-import-meta)
And the following options have different defaults from acorn, to match Node modules:
ecmaVersion: 2019
allowHashBang: true
allowReturnOutsideFunction: true
var walk = require('acorn-node/walk')
The Acorn syntax tree walker. Comes preconfigured for the syntax plugins if necessary. See the acorn documentation for details.
