## Installation
|
|
|
|
```shell
|
|
npm install eleventy-plugin-automatic-noopener
|
|
```
|
|
|
|
|
|
## Usage
|
|
|
|
In your [Eleventy config file](https://www.11ty.dev/docs/config/) (`.eleventy.js` by default):
|
|
```js
|
|
const automaticNoopener = require('eleventy-plugin-automatic-noopener');
|
|
|
|
module.exports = function(eleventyConfig) {
|
|
eleventyConfig.addPlugin(automaticNoopener);
|
|
}
|
|
```
|
|
|
|
|
|
### PostHTML
|
|
If you're already using [PostHTML](https://posthtml.org/) you can reduce build times by using the `posthtml` export as a plugin to your existing PostHTML syntax tree. It provides a stand-alone PostHTML version of Automatic Noopener that can even be used outside of Eleventy.
|
|
|
|
The optional `parser` export further reduces build times when using PostHTML with Eleventy's `--watch` or `--serve` arguments. Parsing your options outside of the transform will mean it's only done once at the start of watching or serving rather than every time Eleventy builds.
|
|
|
|
```js
|
|
const posthtml = require('posthtml');
|
|
const anotherPostHTMLPlugin = require('another-posthtml-plugin');
|
|
const { posthtml: automaticNoopener, parser } = require('eleventy-plugin-automatic-noopener');
|
|
const options = parser({noreferrer: true});
|
|
|
|
module.exports = function(eleventyConfig) {
|
|
eleventyConfig.addTransform('posthtml', function(HTMLString, outputPath) {
|
|
if(outputPath && outputPath.endsWith('.html')) {
|
|
return posthtml([automaticNoopener(options), anotherPostHTMLPlugin()])
|
|
.process(HTMLString)
|
|
.then(result => result.html));
|
|
}
|
|
else {
|
|
return HTMLString;
|
|
}
|
|
});
|
|
}
|
|
```
|
|
|
|
|
|
## Configuration
|
|
```js
|
|
const automaticNoopener = require('eleventy-plugin-automatic-noopener');
|
|
|
|
module.exports = function(eleventyConfig) {
|
|
eleventyConfig.addPlugin(automaticNoopener, {
|
|
ignore: /^https?:\/\/google\.com(\/|$)/i,
|
|
elements: ['a', 'area', 'form'],
|
|
noopener: true,
|
|
noreferrer: false,
|
|
});
|
|
}
|
|
```
|
|
|
|
|
|
### ignore
|
|
- Default: null
|
|
- Accepts: Regular Expression
|
|
|
|
Any URLs that match the given regular expression will not cause `rel="noopener"` or `rel="noreferrer"` attributes to be added to their corresponding element.

|
|
|
### elements

|
- Default: ['a', 'area', 'form']

|
|
|
The elements to add `rel="noopener"` or `rel="noreferrer"` to. Strings must be 'a', 'area' or 'form'.
|
|
|
|
|
|
### noopener
|
|
- Default: True
|
|
- Accepts: Boolean
|
|
|
|
Add a `rel="noopener"` attribute to all elements with unsafe external links that don't have a `rel="noreferrer"` or `rel="opener"` attribute on them. Ignored if [noreferrer](#noreferrer) is true.
|
|
|
|
|
|
### noreferrer
|
|
- Default: False
|
|
- Accepts: Boolean
|
