循环中的意外“等待” no-await-in-loop

Question

I'm getting an error inside the following loop:

Unexpected await inside a loop no-await-in-loop

const deviceSet = {};
for (const target of body.inputs[0].payload.devices) {
    const doc = await firestore().doc(`devices/${target.id}`).get();
    const device = Device.createDevice(doc.id, doc.data());
    deviceSet[device.id] = device.reportState;
   }

Answer 1

You could try it the old fashioned way:

const deviceSet = {};
const target = body.inputs[0].payload.devices;
for (let i = 0; i < body.inputs[0].payload.devices; i++) {
    const doc = firestore().doc(`devices/${target[i].id}`).get();
    const device = Device.createDevice(doc.id, doc.data());
    deviceSet[device.id] = device.reportState;
   }

Answer 2

Recurssion can solve your problem. This is not tested code, you can work on the idea

async function test(i = 0) {
  const deviceSet = {};
  const target = body.inputs[0].payload.devices;
  const doc = await firestore().doc(`devices/${target[i].id}`).get();
  const device = Device.createDevice(doc.id, doc.data());
  deviceSet[device.id] = device.reportState;
  if (i < body.inputs[0].payload.devices) {
    test(i + 1);
  }
}
test(0)
