Cypress not stubbing json data in intercept? - next.js

I've been searching for a solution all day, googling and StackOverflowing, but nothing appears to be working.
I've got a very simple NextJS app. On page load, I load a fact from a third party API automatically. Then a user can enter a search query, press enter, and search again based on that query. I want to create a Cypress test that checks for the functionality of that search feature.
Right now, I'm getting a timeout on cy.wait(), and it states that No request ever occurred.
app.spec.js
import data from '../fixtures/data';
describe('Test search functionality', () => {
it('renders new fact when search is performed', () => {
// Visit page
cy.visit('/');
// Wait for page to finish loading initial fact
cy.wait(1000);
// Intercept call to API
cy.intercept("GET", `${process.env.NEXT_PUBLIC_API_ENDPOINT}/jokes/search?query=Test`, {
fixture: "data.json",
}).as("fetchFact");
// Type in search input
cy.get('input').type('Test');
// Click on search button
cy.get('.submit-btn').click();
// Wait for the request to be made
cy.wait('#fetchFact').its('response.statusCode').should('eq', 200);
cy.get('p.copy').should('contain', data.result[0].value);
})
});
One thing I've noticed, is that the data being displayed on the page is coming from the actual API response, rather than the json file I'm attempting to stub with. None of React code is written server-side either, this is all client-side.
As you can see, the test is pretty simple, and I feel like I've tried every variation of intercept, changing order of things, etc. What could be causing this timeout? Why isn't the json being stubbed correctly in place of the network request?

And of course, I figure out the issue minutes after posting this question.
I realized that Cypress doesn't like Next's way of handling env variables, and instead needed to create a cypress.env.json. I've updated my test to look like this:
import data from '../fixtures/data';
describe('Test search functionality', () => {
it('renders new fact when search is performed', () => {
// Visit page
cy.visit('/');
// Wait for page to finish loading initial fact
cy.wait(1000);
// Intercept call to API
const url = `${Cypress.env('apiEndpoint')}/jokes/search?query=Test`;
cy.intercept("GET", url, {
fixture: "data",
}).as("fetchFact");
// Type in search input
cy.get('input').type('Test');
// Click on search button
cy.get('.submit-btn').click();
// Wait for the request to be made
cy.wait('#fetchFact').its('response.statusCode').should('eq', 200);
cy.get('p.copy').should('contain', data.result[0].value);
})
});

I want to get OrderID from API responce using cy.intercept in cypress

I want to get the order ID from the API response. When I click on the Create Order button it will send a POST API request and return the ID that I want to save in my JSON file.
This is my order creation code.
cy.clickOnElement(practicePageSelectors.CreateOrder).click(); // click on add Rx button
cy.readFile('cypress/fixtures/Data.json').then((profile) => {
cy.searchPatients(practicePageSelectors.searchPatient1, profile.Patient_fullName);
})
cy.searchDoctors(); // search for the doctor
cy.clickOnElementUsingXpath(practicePageSelectors.nextButtonId); // click on the next button
cy.clickOnElement(practicePageSelectors.createOnetimeOrder)
cy.searchMedicine() //search for Medicine
cy.clickOnElementUsingXpathfirst(practicePageSelectors.addMedicine); // click on add button
cy.clickOnElementUsingText(practiceData.paymentButtonName, practiceData.buttonTag); // click on skip payment button
cy.clickOnElementUsingXpath(practicePageSelectors.submit_CreateOrderButton)
And I tried something like this
cy.intercept({
method: 'POST',
url: 'https://ibis-dev.droicelabs.us/api/dispenser/orders/',
}).then((responce)=>{
let body = JSON.parse(responce.body)
cy.log(body)
})
I don't know how to use intercept. Please guide me
You have to register the interceptor before the http call will be made and then wait for the data within your test.
This should happen either in before hook or on top of your actual test case.
cy.intercept({
method: 'POST',
url: 'https://ibis-dev.droicelabs.us/api/dispenser/orders/',
}).as('ordersCall')
and then in place where you will need the ID
cy.wait('#ordersCall')
.its('response.body')
.then((body) => {
// parsing might be not needed always, depends on the api response
const bodyData = JSON.parse(body)
cy.log(bodyData)
})
Side note: cy.fixture() reads directly from fixtures directory - no need to use cy.readFile

I am noticing double entry (cpc and organic) for the same user ? little confused

I'm noticing double entry in google analytics. I have multiple ocurrences where it looks like the user came from the CPC campaign (which always has a 0s session duration) but that very same user also has an entry for "organic" and all the activities are logged under that.
My site is not ranked organically for those keywords. Unless a so many users come to my site, leave, and google for my "brand name" on google and revisits, this doesn't make sense.
I'm a little confused. Here's the report:
preview from google analytics dashboard
Based on the additional information in your comment, that the sites is a Single Page Application (SPA), you are most likely facing the problem of 'Rogue Referral'.
If this is the case, what happens, is that you overwrite the location field in the Analytics hit, losing the original UTM parameters, whereas referral is still sent with the hit, so Analytics recognizes the second hit as a new traffic source. One of the solutions is to store the original page URL and send it as the location, while sending the actual visited URL in the page field.
A very good article on this topic with further tips, by Simo Ahava, is available for your help.
Also please note, that as you have mentioned, that the first hit shows 0 second time on page, you might need to check, whether the first visited page is sent twice. E.g. sending a hit on the traditional page load event, and sending a hit for the same page as a virtual page view.
I have come up with a solution to this problem in a Gatsby website (a SPA), by writing the main logic in the gatsby-browser.js file, inside the onRouteUpdate function.
You can use this solution in other contexts, but please note that the code needs to run at the first load of the page and at every route change.
If you want the solution to work in browsers that do not support URLSearchParams I think you can easily find a polyfill.
Function to retrieve the parameters
// return the whole parameters only if at least one of the desired parameters exists
const retrieveParams = () => {
let storedParams;
if ('URLSearchParams' in window) {
// Browser supports URLSearchParams
const url = new URL(window.location.href);
const params = new URLSearchParams(url.search);
const requestedParams = ['utm_source', 'utm_medium', 'utm_campaign', 'utm_content', 'gclid'];
const hasRequestedParams = requestedParams.some((param) => {
// true if it exists
return !!params.get(param);
});
if (hasRequestedParams) {
storedParams = params;
}
}
return storedParams;
}
Create the full URL
// look at existing parameters (from previous page navigations) or retrieve new ones
const storedParams = window.storedParams || retrieveParams();
let storedParamsUrl;
if (storedParams) {
// update window value
window.storedParams = storedParams;
// create the url
const urlWithoutParams = document.location.protocol + '//' + document.location.hostname + document.location.pathname;
storedParamsUrl = `${urlWithoutParams}?${storedParams}`;
}
Send the value to analytics (using gtag)
// gtag
gtag('config', 'YOUR_GA_ID', {
// ... other parameters
page_location: storedParamsUrl ?? window.location.href
});
or
gtag('event', 'page_view', {
// ... other parameters
page_location: storedParamsUrl ?? window.location.href,
send_to: 'YOUR_GA_ID'
})

Facebook like load new posts in meteor

I'm in the process of learning meteor. I followed the tutorial to create microscope. If some one submits a post meteor will re render the template for all users. This could be very annoying if there are hundreds of posts then the user will come back to the top of the page and loose track of where he was. I want to implement something similar to what facebook has. When a new post is submitted template isn't rendered rather, a button or link will appear. Clicking it will cause the template to re-render and show the new posts.
I was thinking of using observeChanges on the collection to detect any changes and it does stop the page from showing new posts but only way to show them is to reload the page.
Meteor.publish('posts', function(options) {
var self = this, postHandle = null;
var initializing = true;
postHandle = Posts.find({}, options).observeChanges({
added: function(id, post) {
if (initializing){
self.added('posts', id, post);
}
},
changed: function(id, fields) {
self.changed('posts', id, fields);
}
});
self.ready();
initializing = false;
self.onStop(function() { postHandle.stop(); });
});
Is this the right path to take? If yes, how do I alert the user of new posts? Else, what would be a better way to implement this?
Thank you
This is a tricky question but also valuable as it pertains to a design pattern that is applicable in many instances. One of the key aspects is wanting to know that there is new data but not wanting to show it (yet) to the user. We can also assume that when the user does want to see the data, they probably don't want to wait for it to be loaded into the client (just like Facebook). This means that the client still needs to cache the data as it arrives, just not display it immediately.
Therefore, you probably don't want to restrict the data displayed in the publication - because this won't send the data to the client. Rather, you want to send all the (relevant) data to the client and cache it there until it is ready.
The easiest way involves having a timestamp in your data to work from. You can then couple this with a Reactive Variable to only add new documents to your displayed set when that Reactive Variable changes. Something like this (code will probably be in different files):
// Within the template where you want to show your data
Template.myTemplate.onCreated(function() {
var self = this;
var options = null; // Define non-time options
// Subscribe to the data so everything is loaded into the client
// Include relevant options to limit data but exclude timestamps
self.subscribe("posts", options);
// Create and initialise a reactive variable with the current date
self.loadedTime = new ReactiveVar(new Date());
// Create a reactive variable to see when new data is available
// Create an autorun for whenever the subscription changes ready() state
// Ignore the first run as ready() should be false
// Subsequent false values indicate new data is arriving
self.newData = new ReactiveVar(false);
self.autorun(function(computation) {
if(!computation.firstRun) {
if(!self.subscriptionsReady()) {
self.newData.set(true);
}
}
});
});
// Fetch the relevant data from that subscribed (cached) within the client
// Assume this will be within the template helper
// Use the value (get()) of the Reactive Variable
Template.myTemplate.helpers({
displayedPosts = function() {
return Posts.find({timestamp: {$lt: Template.instance().loadedTime.get()}});
},
// Second helper to determine whether or not new data is available
// Can be used in the template to notify the user
newData = function() {
return Template.instance().newData.get();
});
// Update the Reactive Variable to the current time
// Assume this takes place within the template helper
// Assume you have button (or similar) with a "reload" class
Template.myTemplate.events({
'click .reLoad' = function(event, template) {
template.loadedTime.set(new Date());
}
});
I think this is the simplest pattern to cover all of the points you raise. It gets more complicated if you don't have a timestamp, you have multiple subscriptions (then need to use the subscription handles) etc. Hope this helps!
As Duncan said in his answer, ReactiveVar is the way to go. I've actually implemented a simple facebook feed page with meteor where I display the public posts from a certain page. I use infinite scroll to keep adding posts to the bottom of the page and store them in a ReactiveVar. Check the sources on github here and the live demo here. Hope it helps!

Can't put data from a Meteor collection into an array

I'm learning Meteor and I was trying to pass the result of a Collection.find() into and array (using a variable) and the simpler code I have is (in a file that is in the root):
CalEvents = new Mongo.Collection('calevents'); //creating a collection
/*------------------------- Populating the database with dummy data-------*/
if (Meteor.isServer) {
Meteor.startup(function () {
if (CalEvents.find().count() === 0) {
CalEvents.insert({
title: "Initial room",
start: '2010-02-02'
});
}
});
}
/*--------------- Creating an array from the collection-----------------*/
events = [];
calEvents = CalEvents.find({});
calEvents.forEach(function(evt){
events.push({
title: evt.title,
start: evt.start,
})
});
The page has nothing to show but using the console I can see (CalEvents.find().fetch()) that I have data in my database but the "events" variable is empty...
I can't understand why because I tried several other things such as changing file names and moving code to guarantee the proper order.
And I already tried to use CalEvents.find().fetch() to create an array an put the result into a variable but I'm not able to do it...
Does anyone know what's so simple that I'm missing?...
Do you use autosubscribe?
You probably need to make sure the sbscription is ready. See Meteor: How can I tell when the database is ready? and Displaying loader while meteor collection loads.
The reason you do see CalEvents.find().fetch() returning items in the console is that by the time you make that call, the subscription is ready. But in your events = []; ... code (which I assume is in a file under the client directory, you might have assumed that the subscription data has arrived when in fact it has not.
A useful debugging tool is Chrome's device mode ("phone" icon near the search icon in DevTools), which lets you simulate slow networks (e.g. GPRS, with 500ms delay for every request).

Loading data asynchronously in ember-data

I'm writing an application based on ember-data, it loads up all of its data asynchronously. However, the didLoad function does not get called until find is used. For example:
App = Ember.Application.create();
App.Store = DS.Store.create({revision: 3});
App.Thing = DS.Model.extend({
didLoad: function(){
alert("I loaded " + this.get('id'));
}
});
App.Store.load(App.Thing,{id: "foo"});
...will not trigger the alert, and findAll will not return the model. However, when I run:
App.Store.find(App.Thing,"foo");
The didLoad function will trigger, and it can be found with App.Store.findAll(App.Thing).
What's going on?
The ember-data source code explains it well:
// A record enters this state when the store askes
// the adapter for its data. It remains in this state
// until the adapter provides the requested data.
//
// Usually, this process is asynchronous, using an
// XHR to retrieve the data.
loading: DS.State.create({
// TRANSITIONS
exit: function(manager) {
var record = get(manager, 'record');
record.fire('didLoad');
},
// EVENTS
didChangeData: function(manager, data) {
didChangeData(manager);
manager.send('loadedData');
},
loadedData: function(manager) {
manager.goToState('loaded');
}
}),
this means that 'didLoad' will only be triggered when the record was loaded via the adapter.
The 'find' method asks the adapter for the data - this looks it up in the pool of currently available data hashes and in your case finds it, because you already provided it. In other cases however the data maybe does not exist locally in the browser but remain on the server, which would trigger an ajax request in the adapter to fetch it.
So 'didLoad' currently only works in combination with an adapter (e.g: find)
But I totally agree with you that this should be changed since triggering 'didLoad' on models that are loaded vai Store.load seems pretty obvious ;-)
