You can get it on npm.

Add this script to your page.

`

It's also available on jsDelivr and cdnjs.

`html


`

The JavaScript file size is quite huge(about 100kb gzipped) and therefore not suitable to include in mobile pages. It's recommended to make sure eruda is loaded only when eruda is set to true on url(http://example.com/?eruda=true), for example:

`javascript
;(function () {
var src = '//cdn.jsdelivr.net/npm/eruda';
if (!/eruda=true/.test(window.location) && localStorage.getItem('active-eruda') != 'true') return;
document.write('');
document.write('eruda.init();');
})();
`

Configuration

When initialization, a configuration object can be passed in.

* container: Container element. If not set, it will append an element directly
under html root element.
* tool: Choose which default tools you want, by default all will be added.

For more information, please check the documentation.

`javascript
let el = document.createElement('div');
document.body.appendChild(el);

eruda.init({
container: el,
tool: ['console', 'elements']
});
