For example, the following is an async function:
async function encryptPwd() {
const salt = await bcrypt.genSalt(5);
const encryptedPwd = await bcrypt.hash(password, salt);
return encryptedPwd;
}
If the server is lagging a lot, I want to abort this activity and return an error. How can I set a timeout for like 10 sec (for example)?
You could wrap the hash function in another promise.
function hashWithTimeout(password, salt, timeout) {
return new Promise(function(resolve, reject) {
bcrypt.hash(password, salt).then(resolve, reject);
setTimeout(reject, timeout);
});
}
const encryptedPwd = await hashWithTimeout(password, salt, 10 * 1000);
Another option is to use Promise.race() .
function wait(ms) {
return new Promise(function(resolve, reject) {
setTimeout(resolve, ms, 'HASH_TIMED_OUT');
});
}
const encryptedPwd = await Promise.race(() => bcrypt.hash(password, salt), wait(10 * 1000));
if (encryptedPwd === 'HASH_TIMED_OUT') {
// handle the error
}
return encryptedPwd;
