Server rendering

@sealpixel/server renders edit logs with the same WebAssembly core the browser uses. The primitive is a fetch-style handler.

import { createSealpixelHandler, inlineSource, s3Destination, s3Source, urlSource } from '@sealpixel/server';
import { awsObjectStore } from '@sealpixel/server/aws';
import { defaultPlugins } from '@sealpixel/plugins';

const store = awsObjectStore(new S3Client({}));
export const handler = createSealpixelHandler({
  plugins: defaultPlugins,
  sources: [s3Source({ store, bucket: 'uploads' }), urlSource({ allowHosts: ['cdn.example.com'] }), inlineSource()],
  destinations: [s3Destination({ store, bucket: 'renders' })],
  limits: { maxMegapixels: 80, maxBytes: 100e6, timeoutMs: 25_000 },
  cors: ['https://app.example.com'],
});
