# Creating designs
Create a new design with the JavaScript API.
After [setting up the JavaScript API](https://www.canva.dev/docs/button/html/getting-started/), the next step is to allow users to create a design with the Canva editor.
To do this, call the [`createDesign`](https://www.canva.dev/docs/button/javascript/api-reference/create-design/) method:
```javascript
api.createDesign({
design: {
type: "Poster",
},
});
```
At a minimum, the `createDesign` method expects an `opts.design.type` argument. This argument defines the *design type* of a newly created design. The design type determines:
* The dimensions of the user's design.
* The templates that Canva shows to the user.
For a complete list of design types that Canva supports, refer to [Design types](https://www.canva.dev/docs/button/reference/design-types/).
