'astro': patch

|
|
Adds a new function `refreshContent` to the `astro:server:setup` hook that allows integrations to refresh the content layer. This can be used, for example, to register a webhook endpoint during dev, or to open a socket to a CMS to listen for changes.
|
||
|
|
|
||
|
|
By default, `refreshContent` will refresh all collections. You can optionally pass a `loaders` property, which is an array of loader names. If provided, only collections that use those loaders will be refreshed. For example, A CMS integration could use this property to only refresh its own collections.
|
||
|
|
|
||
|
|
You can also pass a `context` object to the loaders. This can be used to pass arbitrary data, such as the webhook body, or an event from the websocket.

```ts
|

|
|
{
|
||
|
|
name: 'my-integration',
|
||
|
|
hooks: {
|
||
|
|
'astro:server:setup': async ({ server, refreshContent }) => {
|
||
|
|
server.middlewares.use('/_refresh', async (req, res) => {
|
||
|
|
if(req.method !== 'POST') {
|
||
|
|
res.statusCode = 405
|
||
|
|
res.end('Method Not Allowed');
|
||
|
|
return
|
||
|
|
}
|
||
|
|
let body = '';
|
||
|
|
req.on('data', chunk => {
|
||
|
|
body += chunk.toString();
|
||
|
|
});
|

req.on('end', async () => {
|

try {
|

const webhookBody = JSON.parse(body);

await refreshContent({
|

context: { webhookBody },

loaders: ['my-loader']

res.writeHead(200, { 'Content-Type': 'application/json' });
|

res.end(JSON.stringify({ message: 'Content refreshed successfully' }));

res.writeHead(500, { 'Content-Type': 'application/json' });
