async function getRedisKeyAsync(key){
var value = await client.get(key);
console.log('got value ' + value + ' for key ' + key + ' in redis');
return value;
}
async function getRedisKeyPromise(key){
client.get(key).then(
(value) => {
console.log('got value ' + value + ' for key ' + key + ' in redis');
return value;
}
);
}
In both cases, value for key is fetched from redis correctly. But a caller of these functions get the value back only in the first case.
var value1 = await myredis.getRedisKeyAsync(req.params.key); // works
var value2 = await myredis.getRedisKeyPromise(req.params.key); // value2 is undefined
How do I rewrite getRedisKeyPromise so that it behaves the same as getRedisKeyAsync ?
