What Changed

To improve error reporting in route definitions, route registration is now synchronous. As a result, if you specify an onRoute hook in a plugin you should now use await.register()

Before

fastify.register((instance, opts, done) => {
instance.addHook('onRoute', (routeOptions) => {
const { path, method } = routeOptions;
console.log({ path, method });
});
done();
});

After

await fastify.register((instance, opts, done) => {
instance.addHook('onRoute', (routeOptions) => {
const { path, method } = routeOptions;
console.log({ path, method });
});
done();
});
