I created an E2E to test for signups, using Nodemailer with Ethereal.
When the test runs the first time everything ends smoothly, but when I executed it a second time the test, for some reason, breaks.
While investigating the above issue, I noticed that the createTestAccount returns the same email address (unless cypress is restarted).
Here's the function code for createTestAccount: https://github.com/nodemailer/nodemailer/blob/master/lib/nodemailer.js#L58.
Is createTestAccount using an internal cache?
If yes, is there a way to disable it (besides setting and process.env.ETHEREAL_CACHE to false)?
Based on the current version (6.7.4) of code, it's not possible to disable the cache any other way than setting the env variable ETHEREAL_CACHE to something different than ['true', 'yes', 'y', '1'].
Aka process.env.ETHEREAL_CACHE needs to be false
Keep in mind that this is OS level env variable. Not the ones setup in Cypress.
And the best thing is the great documentation which mentions ETHEREAL_CACHE variable ...
const request = require("request");
async function createEmail (callback) {
request.post({
headers: { "content-type" : "application/json" },
method: "POST",
url: "https://api.nodemailer.com/user",
body: Buffer.from(
JSON.stringify({
requestor: "nodemailer",
version: "6.7.8"
})
)
}, (err, res, body) => {
if(err)
return callback("Failed to handle request!");
const data = JSON.parse(body) || null;
if(typeof(data) !== "object" || typeof(data.status) !== "string")
return callback("Failed to resolve data");
delete data.status;
return callback(false, data);
});
};
createEmail((err, account) => {
if(err)
return console.log(err);
console.log(account);
});

I have a PWA project where I send the data to server. During this process, if the user is offline then the data is stored in indexedDb and a sync tag is registered. So, then when the user comes online that data can sent to the server.
But In my case the sync event gets executed immediately when the we register a sync event tag, which means the data is tried to be sent to server while its offline, which is not going to work.
I think the sync event supposed to fire while its online only, what could be issue here ?
The service worker's sync event works accordingly when I tried to enable and disable the offline option of chrome devtools, and also works correctly in my android phone.
This is how I register my sync tag
function onFailure() {
var form = document.querySelector("form");
//Register the sync on post form error
if ('serviceWorker' in navigator && 'SyncManager' in window) {
navigator.serviceWorker.ready
.then(function (sw) {
var post = {
datetime1: form.datetime1.value,
datetime: form.datetime.value,
name: form.name.value,
image: form.url.value,
message: form.comment.value
};
writeData('sync-comments', post)
.then(function () {
return sw.sync.register('sync-new-comment');
})
.then(function () {
console.log("[Sync tag registered]");
})
.catch(function (err) {
console.log(err);
});
});
}
}
And this is how the sync event is called
self.addEventListener('sync', function (event) {
console.log("[Service worker] Sync new comment", event);
if (event.tag === 'sync-new-comment') {
event.waitUntil(
readAllData('sync-comments')
.then(function (data) {
setTimeout(() => {
data.forEach(async (dt) => {
const url = "/api/post_data/post_new_comment";
const parameters = {
method: 'POST',
headers: {
'Content-Type': "application/json",
'Accept': 'application/json'
},
body: JSON.stringify({
datetime: dt.datetime,
name: dt.name,
url: dt.image,
comment: dt.message,
datetime1: dt.datetime1,
})
};
fetch(url, parameters)
.then((res) => {
return res.json();
})
.then(response => {
if (response && response.datetimeid) deleteItemFromData('sync-comments', response.datetimeid);
}).catch((error) => {
console.log('[error post message]', error.message);
})
})
}, 5000);
})
);
}
});
you mention
The service worker's sync event works accordingly when I tried to enable and disable the offline option of chrome devtools, and also works correctly in my android phone.
So I'm not sure which case is the one failing.
You are right that the sync will be triggered when the browser thinks the user is online, if the browser detects that the user is online at the time of the sync registration it will trigger the sync:
In true extensible web style, this is a low level feature that gives you the freedom to do what you need. You ask for an event to be fired when the user has connectivity, which is immediate if the user already has connectivity. Then, you listen for that event and do whatever you need to do.
Also, from the workbox documentation
Browsers that support the BackgroundSync API will automatically replay failed requests on your behalf at an interval managed by the browser, likely using exponential backoff between replay attempts.
Basically, my question is the exact one here https://github.com/axios/axios/issues/583. It can be done via throw new axios.Cancel('Operation canceled by the user.');.. But how can I do this in nuxt axios module?? I can not see it in the document and I tried $axios.Cancel('Error') but returned $axios.Cancel is not a constructor
Basically, the something like the snippet below is what I am looking for:
axios.interceptors.response.use(function (response) {
throw new axios.Cancel('Operation canceled by the user.');
}, function (error) {
return Promise.reject(error);
});
Emphasis on throw new axios.Cancel
While #nuxtjs/axios does not expose axios.Cancel, you could still import axios directly to get that symbol. Note axios is already a dependency of #nuxtjs/axios, so no extra dependency necessary.
Example (tested with #nuxtjs/axios v5.11.0):
// plugins/axios.js
import { Cancel } from 'axios'
export default function ({ $axios }) {
$axios.onResponse((response) => {
if (response.code !== 200){
throw new Cancel(response.msg)
}
})
}
With nuxt/axios v5.8.0 IsCancel available
v5.8.0 add CancelToken and isCancel to axios instance
Seems like nuxt-axios does not have any exact equivalent but I found a work around.
plugins/axios.js
export default function({ $axios, req, store, redirect, app }, inject) {
// const source = $axios.CancelToken.source()
const timeout = process.env.API_TIMEOUT || 10000
const errorHandling = function(error) {
console.log(`API ${error}`)
return new Promise(() => {})
}
$axios.onResponse((response) => {
// Any condition that could be considered an response based on standard response
if(response.code !== 200){
throw response.msg
}
})
So I am sending data of a mission, the startdate and the finish date. However I am not able to put any changes into the database as it believes I get an immutable error with mongoDB... I would like to stick with using the .then method for my js code.
My other methods are working properly, I just can't get this update method right...
app.put('/missions/:id', function (req, res) {
if (req.user) {
model.Mission.findById(req.params.id).then(function(Mission){
console.log("req.body.secret_mission: ",req.body.secret_mission)
Mission['secret_mission'] = req.body.secret_mission;
Mission['start'] = req.body.start;
Mission['complete'] = req.body.complete;
Mission.update().then(function(){
res.set('Access-Control-Allow-Origin', '*');
res.sendStatus(201);
});
});
}else{
res.sendStatus(401);
}
});
Error I receive in the command line
I was able to use all the help provided to come up with a working solution and keep consistent to how I am calling the rest of my code. A big thanks to those that responded!!
Rather than setting the elements in my collection beforehand I am supposed to do it in the update request. Instead of calling 2 methods I used the findOneAndUpdate.
app.put('/missions/:id', function (req, res) {
if (req.user) {
model.Mission.findOneAndUpdate(
{'_id' : req.params.id},
{ $set: {"secret_mission" : req.body.secret_mission,
"start" : req.body.start},
"complete" : req.body.complete
}).then(function(err, missions){
if (err) return res.json({Error: err});
res.json(missions);
});
} else {
res.sendSatus(401);
}
});
I've cleaned up Your code:
removed req.user check to middleware,
included cors module to not to play with CORS headers in every handler
used async/await stuff to give it more synchronous look
mission/:id route handler just have concrete logic without garbage
Check this solution:
const cors = require('cors'); // install: npm i --save cors
const _ = require('lodash'); // install: npm i --save lodash
app.use(cors());
const isUserAuthorized = (req, res, next) => {
if (!req.user) return res.status(401).send();
next();
}
app.put(
'/missions/:id',
isUserAuthorized,
async (req, res) => {
try {
const mission = await model.Mission.findById(req.params.id);
if (!mission) return res.status(404).send();
mission.set(_.pick(req.body, ['secret_mission', 'start', 'complete']);
await mission.save();
res.status(201).send();
}
catch (error) {
console.log(error);
res.status(500).send();
}
});
or if You don't care if record in db exist or not, so You can just push update directly:
app.put(
'/missions/:id',
isUserAuthorized,
async (req, res) => {
try {
const data = _.pick(req.body, ['secret_mission', 'start', 'complete']);
await model.Mission.update({_id: req.params.id}, {$set: data});
res.status(201).send();
}
catch (error) {
console.log(error);
res.status(500).send();
}
});
I have a mongoose schema with a unique field and I am trying to write a backend (express) integration test which checks that POSTing the same entity twice results in HTTP 400. When testing manually behaviour is as excpected. Automatic testing however requires a wait:
it('should not accept two projects with the same name', function(done) {
var project = // ...
postProjectExpect201(project,
() => {
setTimeout( () => {
postProjectExpect400(project, done);
},100);
}
);
});
The two post... methods do as named and the code above works fine, but if the timeout is removed, BOTH requests receive HTTP 200 (though only one entity created in the database).
I'm new to those technologies and I'm not sure what's going on. Could this be a mongodb related concurrency issue and if so how should I deal with it?
The database call looks like this:
Project.create(req.body)
.then(respondWithResult(res, 201))
.catch(next);
I already tried connecting to mongodb with ?w=1 option btw.
Update:
To be more verbose: Project is a mongoose model and next is my express error handler which catches the duplicate error.
The test functions:
var postProjectExpect201=function(project, done, validateProject) {
request(app)
.post('/api/projects')
.send(project)
.expect(201)
.expect('Content-Type', /json/)
.end((err, res) => {
if (err) {
return done(err);
}
validateProject && validateProject(res.body);
done();
});
};
var postProjectExpect400=function(project, done) {
request(app)
.post('/api/projects')
.send(project)
.expect(400)
.end((err, res) => {
if (err) {
return done(err);
}
done();
});
};
I'm trying to create a Facebook chatbot with NodeJS, Express, and a Heroku server.
I created my webhook on heroku and had it verified and saved by facebook. I then started adding code that would reply to the incoming messages and I can't seem to get it connected. It keeps saying "Error, wrong validation token" when I try to load my webhook in my browser. And when I try to send my bot a message I get no response. Even though I already had it verified and didn't change the code.
Here is my code:
var express = require('express');
var bodyParser = require('body-parser');
var app = express();
var port = process.env.PORT || 3000;
// body parser middleware
app.use(bodyParser.urlencoded({ extended: true }));
// test route
//app.get('/', function (req, res) { res.status(200).send('Hello world!') });
app.get('/', function (req, res) {
if (req.query['hub.verify_token'] === '8FKU9XWeSjnZN4ae') {
res.send(req.query['hub.challenge']);
}
res.send('Error, wrong validation token');
})
app.post('/', function (req, res) {
messaging_events = req.body.entry[0].messaging;
for (i = 0; i < messaging_events.length; i++) {
event = req.body.entry[0].messaging[i];
sender = event.sender.id;
if (event.message && event.message.text) {
text = event.message.text;
sendTextMessage(sender, "Text received, echo: "+ text.substring(0, 200));
}
}
res.sendStatus(200);
});
// error handler
app.use(function (err, req, res, next) {
console.error(err.stack);
res.status(400).send(err.message);
});
app.listen(port, function () {
console.log('Listening on port ' + port);
});
var token = <myToken>;
function sendTextMessage(sender, text) {
messageData = {
text:text
}
request({
url: 'https://graph.facebook.com/v2.6/me/messages',
qs: {access_token:token},
method: 'POST',
json: {
recipient: {id:sender},
message: messageData,
}
}, function(error, response, body) {
if (error) {
console.log('Error sending message: ', error);
} else if (response.body.error) {
console.log('Error: ', response.body.error);
}
});
}
So I'm confused as to why nothing is happening and why I'm getting that error. I feel like I'm missing a whole step. I am following this tutorial by the way: https://developers.facebook.com/docs/messenger-platform/quickstart
Any help is appreciated. Thanks!
Edit: Here are my heroku logs
Do not post your full access tokens here!
Have you tested the output of the challenge? Since it's just a GET and you know all values you can try it yourself: your-app-domain.com/your-callback-url?hub_mode=subscribe&hub_verify_token=the_token_you_set_in_your_app_config&hub_challenge=ping which sould print 'ping' if everything work fine.
Make sure you add sendStatus(200) to the hub challenge response, too.
You need to subscribe your page to the app first. To do so make a POST request to /your-page-id/subscribed_apps which should return "success". You can make a GET request to the same endpoint afterwards to double check your app is subscribed to your page
You did not mention which events you subscribed to (needs to be message_deliveries, messages, messaging_optins, messaging_postbacks)
Make sure the webhooks tab in your app dashboard now says "complete"
Test again
You are actually using "request" but you are never importing it anywhere. Here's how to fix it:
var request = require("request")
Once you have added that to your index.js or app.js file (basically whatever this file is), make sure you do:
npm install request --save
This should fix it. Unfortunately, Heroku doesn't error out and say that it does not know what "request" is and that's why it was so hard to figure this out in the first place!
