## Installation
First, install the `tldraw` package:
```bash
npm i tldraw
```
> The tldraw SDK [does not follow semantic versioning](/releases-versioning).
## Usage
You can use the [Tldraw](?) component inside of any React component.
```tsx
import { Tldraw } from 'tldraw'
import 'tldraw/tldraw.css'
export default function () {
return (
<div style={{ position: 'fixed', inset: 0 }}>
<Tldraw />
</div>
)
}
```
### Wrapper
It's important that the [Tldraw](?) component is wrapped in a parent container that has an explicit size. Its height and width are set to `100%`, so it will fill its parent container.
### CSS
In addition to the [Tldraw](?) component itself, you should also import the `tldraw.css` file from the `tldraw` package.
```tsx
import 'tldraw/tldraw.css'
```
You can alternatively import this file inside of another CSS file using the `@import` syntax.
```css
@import url('tldraw/tldraw.css');
```
If you'd like to deeply change the way that tldraw looks, you can copy the `tldraw.css` file into a new CSS file, make your changes, and import that instead.
### Fonts
We also use Inter as the default tldraw font. You can import this font however you like (or use a different font!) but here's the CSS import from Google fonts that we use:
```css
@import url('https://fonts.googleapis.com/css2?family=Inter:wght@500;700&display=swap');
```
### HTML
If you're using the [Tldraw](?) component in a full-screen app, you probably also want to update your `index.html`'s meta viewport element as shown below.
```html
<meta name="viewport" content="width=device-width, initial-scale=1, viewport-fit=cover" />
```
This may not be critical to [Tldraw](?) performing correctly, however some features (such as safe area positioning) will only work correctly if these viewport options are set.
## Server Rendering
The [Tldraw](?) component can't be server-rendered. If you're using the component in a server-rendered framework (such as Next.js) then you need to import it dynamically.
```tsx
const Tldraw = dynamic(async () => (await import('tldraw')).Tldraw, { ssr: false })
```
### Using a bundler
If you're using a bundler like webpack or rollup, you can import the assets directly from the `assets` package. Here you can use `getAssetUrlsByMetaUrl` helper function:
```tsx
import { getAssetUrlsByMetaUrl } from 'assets/urls'
const assetUrls = getAssetUrlsByMetaUrl()
<Tldraw assetUrls={assetUrls} />
```
## Usage in Frameworks
Visit our [framework examples repository](https://github.com/tldraw/examples) to see examples of tldraw being used in various frameworks.
## Static Assets
In order to use the [Tldraw](?) component, the app must be able to find certain assets. These are contained in the `embed-icons`, `fonts`, `icons`, and `translations` folders. We offer a few different ways of making these assets available to your app.
### Using a public CDN
By default we serve these assets from a public CDN. Everything should work out of the box and is a good way to get started.
If you would like to customize some of the assets you can pass the customizations to our [Tldraw](?) component. For example, to use a custom icon for the `hand` tool you can do the following:
```tsx
const assetUrls = {
icons: {
'tool-hand': './custom-tool-hand.svg',
},
}
<Tldraw assetUrls={assetUrls} />
```
This will use the custom icon for the `hand` tool and the default assets for everything else.
### Self-hosting static assets
If you want more flexibility you can also host these assets yourself:
1. Download the `embed-icons`, `fonts`, `icons`, and `translations` folders from the [assets folder](https://github.com/tldraw/tldraw/tree/main/assets) of the tldraw repository.
2. Place the folders in your project's public path.
3. Pass `assetUrls` prop to our `<Tldraw/>` component to let the component know where the assets live.
You can use our `getAssetUrls` helper function from the `@tldraw/assets` package to generate these urls for you.
```tsx
import { getAssetUrls } from '@tldraw/assets/selfHosted'
const assetUrls = getAssetUrls()
<Tldraw assetUrls={assetUrls} />
```
While these files must be available, you can overwrite the individual files: for example, by placing different icons under the same name or modifying / adding translations.
If you use a CDN for hosting these files you can specify the base url of your assets. To recreate the above option of serving the assets from our CDN you would do the following:
```ts
import { getDefaultCdnBaseUrl } from 'tldraw'
const assetUrls = getAssetUrls({
baseUrl: getDefaultCdnBaseUrl(),
})
```
## Subcomponents
The [Tldraw](?) component combines two lower-level components: [TldrawEditor](?) and TldrawUi. If you want to have more granular control, you can use those lower-level components directly. See [this example](https://github.com/tldraw/tldraw/blob/main/apps/examples/src/examples/exploded/ExplodedExample.tsx) for reference.
### Customize the default components
You can customize the appearance of the tldraw editor and ui using the [Tldraw](?) (or [TldrawEditor](?)) component's `components` prop.
```tsx
const components: TLComponents = {
Background: YourCustomBackground,
SvgDefs: YourCustomSvgDefs,
Brush: YourCustomBrush,
ZoomBrush: YourCustomBrush,
CollaboratorBrush: YourCustomBrush,
Cursor: YourCustomCursor,
CollaboratorCursor: YourCustomCursor,
CollaboratorHint: YourCustomCollaboratorHint,
CollaboratorShapeIndicator: YourCustomdicator,
Grid: YourCustomGrid,
Scribble: YourCustomScribble,
SnapLine: YourCustomSnapLine,
Handles: YourCustomHandles,
Handle: YourCustomHandle,
CollaboratorScribble: YourCustomScribble,
ErrorFallback: YourCustomErrorFallback,
ShapeErrorFallback: YourCustomShapeErrorFallback,
ShapeIndicatorErrorFallback: YourCustomShapeIndicatorErrorFallback,
Spinner: YourCustomSpinner,
SelectionBackground: YourCustomSelectionBackground,
SelectionForeground: YourCustomSelectionForeground,
HoveredShapeIndicator: YourCustomHoveredShapeIndicator,
// ...
}
<Tldraw components={components}/>
