# 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.)
|
|
|
|
```javascript
|
|
import Chart from 'chart.js';
|
|
var myChart = new Chart(ctx, {...});
|
|
```
|
|
|
|
**Note:** Moment.js is installed along Chart.js as dependency. If you don't want to use Moment.js (either because you use a different date adapter or simply because don't need time functionalities), you will have to configure your bundler to exclude this dependency (e.g. using [`externals` for Webpack](https://webpack.js.org/configuration/externals/) or [`external` for Rollup](https://rollupjs.org/guide/en#peer-dependencies)).
|
|
|
|
```javascript
|
|
// Webpack
|
|
{
|
|
externals: {
|
|
moment: 'moment'
|
|
}
|
|
}
|
|
```
|
|
|
|
```javascript
|
|
// Rollup
|
|
{
|
|
external: {
|
|
['moment']
|
|
}
|
|
}
|
|
```
|
|
|
|
## 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:** starting v2.8, Moment.js is an optional dependency for `Chart.js` and `Chart.min.js`. In order to use the time scale with Moment.js, you need to make sure Moment.js is fully loaded **before** requiring Chart.js. You can either use a shim:
|
|
|
|
```javascript
|
|
require.config({
|
|
shim: {
|
|
'chartjs': {
|
|
deps: ['moment'] // enforce moment to be loaded before chartjs
|
|
}
|
|
},
|
|
paths: {
|
|
'chartjs': 'path/to/chartjs/dist/Chart.min.js',
|
|
'moment': 'path/to/moment'
|
|
}
|
|
});
|
|
|
|
require(['chartjs'], function(Chart) {
|
|
new Chart(ctx, {...});
|
|
});
|
|
```
|
|
|
|
or simply use two nested `require()`:
|
|
|
|
```javascript
|
|
require(['moment'], function() {
|
|
require(['chartjs'], function(Chart) {
|
|
new Chart(ctx, {...});
|
|
});
|
|
});
|
|
```
|
|
|
|
## Content Security Policy
|
|
|
|
By default, Chart.js injects CSS directly into the DOM. For webpages secured using [Content Security Policy (CSP)](https://developer.mozilla.org/en-US/docs/Web/HTTP/CSP), this requires to allow `style-src 'unsafe-inline'`. For stricter CSP environments, where only `style-src 'self'` is allowed, the following CSS file needs to be manually added to your webpage:
|
|
|
|
```html
|
|
<link rel="stylesheet" type="text/css" href="path/to/chartjs/dist/Chart.min.css">
|
|
```
|
|
|
|
And the style injection must be turned off **before creating the first chart**:
|
|
|
|
```javascript
|
|
// Disable automatic style injection
|
|
Chart.platform.disableCSSInjection = true;
|
|
```
