# Development Server
|
||
|
|
|
||
|
|
The development server comes as part of the Astro CLI. Start the server with:
|
||
|
|
|
||
|
|
```shell
|
||
|
|
astro dev
|
||
|
|
```
|
||
|
|
|
||
|
|
In your project root. You can specify an alternative
|
||
|
|
|
||
|
|
## Special routes
|
||
|
|
|
||
|
|
The dev server will serve the following special routes:
|
||
|
|
|
||
|
|
### /400
|
||
|
|
|
||
|
|
This is a custom __400__ status code page. You can add this route by adding a page component to your `astro/pages` folder:
|
||
|
|
|
||
|
|
```
|
||
|
|
├── astro/
|
||
|
|
│ ├── components/
|
||
|
|
│ └── pages/
|
||
|
|
│ └── 400.astro
|
||
|
|
```
|
||
|
|
|
||
|
|
For any URL you visit that doesn't have a corresponding page, the `400.astro` file will be used.
|
||
|
|
|
||
|
|
### /500
|
||
|
|
|
||
|
|
This is a custom __500__ status code page. You can add this route by adding a page component to your `astro/pages` folder:
|
||
|
|
|
||
|
|
```astro
|
||
|
|
├── astro/
|
||
|
|
│ ├── components/
|
||
|
|
│ └── pages/
|
||
|
|
│ └── 500.astro
|
||
|
|
```
|
||
|
|
|
||
|
|
This page is used any time an error occurs in the dev server.
|
||
|
|
|
||
|
|
The 500 page will receive an `error` query parameter which you can access with:
|
||
|
|
|
||
|
|
```
|
||
|
|
---
|
||
|
|
const error = import.meta.request.url.searchParams.get('error');
|
||
|
|
---
|
||
|
|
|
||
|
|
<strong>{error}</strong>
|
||
|
|
```
|
||
|
|
|
||
|
|
A default error page is included with Astro so you will get pretty error messages even without adding a custom 500 page.
