Drizzle better-sqlite3 WAL mode

Hello! Sorry if this was asked before but I couldn’t find a way to do it by searching. How should you enable WAL mode with drizzle? Is it enough to put it inside a migration file, or you need to somehow execute it when you connect

Server Sent Events

Hello guys! Sorry if this was asked before. I'm trying to implement an event emitter with SSE like this:

const emitter = new EventEmitter();

app.use("/sse/*", async (c, next) => {
  c.header("Content-Type", "text/event-stream");
  c.header("Cache-Control", "no-cache");
  c.header("Connection", "keep-alive");
  await next();
});

app.post('/message', async (c) => {
  const message = 'test';
  emitter.emit('message', message);
  return c.json({message});
})

app.get('/sse', async (c) => {
  return streamSSE(c, async (stream) => {
   
  const handler = async (message: string) => {
      await stream.writeSSE({
        data: message,
        event: "message"
      });
    }

    stream.onAbort(() => {
      console.log('Connection aborted');
    })

    emitter.on('message', handler);
})
})

const emitter = new EventEmitter();

app.use("/sse/*", async (c, next) => {
  c.header("Content-Type", "text/event-stream");
  c.header("Cache-Control", "no-cache");
  c.header("Connection", "keep-alive");
  await next();
});

app.post('/message', async (c) => {
  const message = 'test';
  emitter.emit('message', message);
  return c.json({message});
})

app.get('/sse', async (c) => {
  return streamSSE(c, async (stream) => {
   
  const handler = async (message: string) => {
      await stream.writeSSE({
        data: message,
        event: "message"
      });
    }

    stream.onAbort(() => {
      console.log('Connection aborted');
    })

    emitter.on('message', handler);
})
})

but it seems it goes directly in the onError on frontend because it closes the stream
