# Integration
Chart.js can be integrated with plain JavaScript or with different module loaders. The examples below show how to load Chart.js in different systems.
## Script Tag
```html
<script src="path/to/chartjs/dist/chart.js"></script>
<script>
var myChart = new Chart(ctx, {...});
</script>
```
## Common JS
```javascript
var Chart = require('chart.js');
var myChart = new Chart(ctx, {...});
```
## Bundlers (Webpack, Rollup, etc.)
Chart.js 3 is tree-shakeable, so it is necessary to import and register the controllers, elements, scales and plugins you are going to use.
For all available imports see the example below.
```javascript
import {
Chart,
ArcElement,
LineElement,
BarElement,
PointElement,
BarController,
BubbleController,
DoughnutController,
LineController,
PieController,
PolarAreaController,
RadarController,
ScatterController,
CategoryScale,
LinearScale,
LogarithmicScale,
RadialLinearScale,
TimeScale,
TimeSeriesScale,
Decimation,
Filler,
Legend,
Title,
Tooltip
} from 'chart.js';
Chart.register(
ArcElement,
LineElement,
BarElement,
PointElement,
BarController,
BubbleController,
DoughnutController,
LineController,
PieController,
PolarAreaController,
RadarController,
ScatterController,
CategoryScale,
LinearScale,
LogarithmicScale,
RadialLinearScale,
TimeScale,
TimeSeriesScale,
Decimation,
Filler,
Legend,
Title,
Tooltip
);
var myChart = new Chart(ctx, {...});
```
A short registration format is also available to quickly register everything.
```javascript
import { Chart, registerables } from 'chart.js';
Chart.register(...registerables);
```
And finally there is an separate path to do just the above for you, in one line:
```javascript
import Chart from 'chart.js/auto';
```
## Require JS
**Important:** RequireJS [can **not** load CommonJS module as is](https://requirejs.org/docs/commonjs.html#intro), so be sure to require one of the UMD builds instead (i.e. `dist/chart.js`, `dist/chart.min.js`, etc.).
```javascript
require(['path/to/chartjs/dist/chart.min.js'], function(Chart){
var myChart = new Chart(ctx, {...});
});
```
**Note:** in order to use the time scale, you need to make sure [one of the available date adapters](https://github.com/chartjs/awesome#adapters) and corresponding date library are fully loaded **after** requiring Chart.js. For this you can use nested requires:
```javascript
require(['chartjs'], function(Chart) {
require(['moment'], function() {
require(['chartjs-adapter-moment'], function() {
new Chart(ctx, {...});
});
});
});
```
