Apps That Use The Spotify Api Plugin
How to call the Spotify Public API. First step, head over to the Spotify Public API package page! Next, pick the endpoint you’d like to call. Finally, fill in the parameters and click “Test Function.” Bam! You’ve just called the Spotify API. Some Spotify API endpoints require a Spotify ID for a certain artist. In order to begin building an app that will use the Spotify API, we first have to create a new Spotify app through the Spotify developer portal. Once on the page, hit the Login button to login to. Spotify Spotify is a subscription music streaming service. The Spotify Web API Track this API allows developers to use their application to get data from the Spotify music catalog. The endpoints results in JSON format providing information such as artists, albums, and tracks directly from the Spotify catalog.
The first step is to sign up for Slack and visit the Slack Apps page. Click
Create New App
and give it a name.Note: The Slack Apps website and the Slack App might have changed since this article was written.
Once the app is created we’ll need to grab the
Signing Secret
from the App Credentials
section. When requests are made from Slack to our server, we need to ensure that not only did the request actually came from Slack, but from our Slack app. Add the secret to either your .zshrc
, .bashrc
or .env.development
file.There are two features we need to add to the app:
Slash Commands
and Event Subscriptions
.Slash Commands
Find the section for Slash Commands on the Slack apps page and create a new one. For the command, enter
/create-playlist
. The request URL is going to be an ngrok
URL. See Part 1 for details on setting up ngrok
. Add the ngrok
URL to this form when we set up the server later in this article.Add a description and a hint. For the hint you can enter
name, description
because that will be the format of how the request will be sent.Event Subscriptions
Find the section for Event Subscriptions on the Slack apps page and turn it on. Add the
ngrok
URL to the Request URL form field once we create a server later in this post.We also need to add a bot event. Create a new bot event under the
Subscribe to bot events
section. The event we need to listen to is message.channels
Add the App to Slack
Go to the Slack channel you want to add the app to. Click
Details
and under More
click Add apps
. Select your app and give it permission to read messages.Creating The Slash Command Server
First, install the necessary dependencies:
In a new file
src/slack/index.js
add the following:Here we have an express server running on port 5000.
To start the server use
nodemon
and use ngrok
to tunnel the requestAdd this URL to the slash command configuration we setup in the first section. The URL should look like:

Let’s break down this code line by line. When a
POST
request is made to the /command
route, we begin by extracting our the message text
from the request body req.body
. We then split the text by a comma because our message format is [playlist name] , [playlist description]
. Now that we have extracted out the name and description we can make a POST
request to the Spotify server /playlist
route to create it. Once that request completes, we send back the playlist URL to the slack channel.Download verbatim for word mac. When we execute the slash command, Slack will make a
POST
request to our server running on port 5000 at the /command
path. To execute the command enter this into the Slack chat:The body of the request to our server will contain the text after
/create-playlist
.Creating The Event Subscription Server
To keep things simple, we’ll add the event subscription server in the same file. We could have just used one server to handle both requests (message events and slash commands). However to make the code easier to read and maintain I made two separate servers.
The
@slack/events-api
library makes it easy to connect to events that the Slack app listens to. First, we import the createEventAdapter
from the library and pass in the signing secret to initialize it. This is crucial because we need to verify that the request we receive is legitimate.Next we run an immediately invoked function to start the server on port 4000. Now that the server is setup we need to listen for message events. The
@slack/events-api
library makes this super simple for us:The code above listens for the
message
event from Slack. If the message body contains a Spotify URL then it makes a request to the Spotify server we created in Part 1.Restart the server and run
ngrok
on both ports:Copy the
ngrok
URL for port 4000 and add it to the Slack app Event Subscriptions configuration we set up in the previous section.If you have your Spotify app running and the Slack app added to a channel, sending a Spotify URL should now add the song to a playlist.
Summary
That’s it! We have seen how we can set up a Slack app which listens slash commands and event subscriptions. Using the command we were able to hit a Spotify server we wrote previously to create a playlist. Our Slack server listens to messages so when a Spotify song gets messaged we can hit our Spotify server again with a request to add that song to the playlist.

The purpose of this post is to tell the story of the new Spotify web player. How and why it came to be. We will focus on what the steps were that led to a complete rewrite and how the lessons learned influenced the experience and the tech decisions of the new web player for desktop browsers.
Using the Web to implement Spotify applications at Spotify
Spotify has been using web technologies for a long time. Before tools like Electron became a reality for building hybrid applications, Spotify started using Chromium Embedded Framework (CEF) in 2011 to embed web views on the desktop application. This made it easier to build and iterate on different parts of the application without having to perform full releases. It was also the foundation used to integrate a myriad of third party apps built using web technologies, what we called Spotify Apps.
Spotify’s web player was released in 2012 and complemented the experience on desktop devices. It made it possible for users to play music from Spotify as quickly as possible, without needing to download and install any application.
The architecture of the web player followed the same approach as the desktop application. The views were isolated from each other using iframes, and this allowed the teams to iterate on and release them without interfering with the rest of the application. Epson v600 scanner software for mac.
In addition, the code for the views was identical on both desktop and web player. Thus, the team working on the Playlist view would implement a new feature, and make it available on the desktop application and the web player, without having to care about the underlying infrastructure.
The architecture of the web player was ideal for consistency between platforms, and fit how the company was organized in feature teams. It also had its drawbacks.
Having iframes for every feature and having that feature load their own JS and CSS might have worked well for the desktop application, which the user downloads bundled with all the resources that it needs. The web player, on the other hand, had to download many resources every time the user navigated between views, which resulted in long load times, which impacted user experience.
Considering a new Web Player
Over the years, we got better at prioritizing a core set of features. With the rise of smartphones, we learned how to strive for removing clutter, properly A/B test features and understand better what was really needed to deliver a good user experience.
In the summer of 2016 we decided to improve the web player. We realized that the architecture of isolated views was difficult to maintain and was preventing us from building a better product. We wanted to go back to basics and support a set of core features (eg playback, library management, and search) and work our way from there.
We found inspiration in the Spotify application for TV and video consoles. This application is a web-based Single Page Application, and uses the Spotify Web API that combines the access to lots micro services to create a unified interface to manipulate Spotify data. It represented a good example of a light client being built by a single team leveraging existing libraries at Spotify.
We researched the feasibility of upgrading the web player, rewriting view by view. In parallel, we started working on a prototype following a similar architecture to the TV application. How do i get rid of mac cleaner pop up?.
After considering the two approaches, we decided on the latter.

Apps That Use The Spotify Api App
- The system to deliver the code for the views, that worked in isolation from each other, wasn’t used by the desktop application anymore and it was too complex for the web player use case.
- The web player was based on lots of libraries and frameworks that were quite outdated. Giving every team an isolated environment to run their code also resulted in them choosing different client-side stacks to build their views.
- The web player was built by multiple teams with over 40 developers but now would be maintained by a dedicated team of 5 developers.
- It was very slow to iterate upon and experiment, especially when it came to making changes across multiple views like updating the visual style.
The birth of a new Web Player
Apps That Use The Spotify Api Playlists
We decided not to repeat the mistakes of the past, so before deciding the feature set that the new web player should have, we ran A/B tests on the existing web player. For some users we removed certain features and we measured their impact in user engagement. After getting the results we decided on the bare minimum feature set that we would feel comfortable with releasing and that our users would enjoy.
We built a Minimum Viable Product (MVP) in a few weeks using our new infrastructure based on Spotify’s Web API. During the following months, we carried out extensive user testing and improved the prototype based on the gathered feedback. Once we felt comfortable, we released it to a small percentage of users side-by-side with the existing web player, and checked the performance amongst them closely.
Our hypothesis was proven. The simpler and faster web player outperformed the old web player in all key metrics.
The tech architecture
Spotify App For Mac
The new Web Player is in line with the overall Spotify look and feel and is built on HTML5 standards. It drops Flash in favor of Encrypted Media Extensions (EME) for music playback, which is supported natively by most modern browsers. It is fast, even on spotty connections, responsive and we have focused on making it enjoyable to use.
The architecture is based on React + Redux, which has made it easier for us to share components between the views, to have a clear data flow and to improve debuggability and testability. Although the components are not shared with other Spotify clients, we see a trend in other Spotify web development teams who are also embracing a similar approach to building web experiences.
Making the decision to embrace well-known open-source solutions and avoiding using Spotify custom libraries allowed us to onboard new developers quickly. This has led to numerous contributions from web developers from all over the company.
Having a simpler architecture allowed us to experiment faster and add features that didn’t exist in the old Web Player, like Daily Mixes, video and audio podcasts, and Connect. On top of that, we were also able to build fast CI/CD pipelines. Now with every commit the latest version of the web player is reaching our users immediately. Finally, we have a web player leveraging today’s technologies. As an example, we added support for Progressive Web App on Chrome OS, so the web player is installed and run as a regular desktop application.
We are excited to continue building a good product for our users on the web.
