Junaid Kabani goes over his tech choices for building a custom Shopify app. It's all hosted on a $20 a month DigitalOcean server.

In this episode of Running in Production, Junaid Kabani goes over how he
built and deploys Openship which is a Shopify app
that was written in Koa. The front-end uses React.

We covered a lot of ground in this episode, such as how Prisma, Apollo, Next.js
and React all come together to build an app that uses Shopify’s API. There’s
also quite a lot of details on the value of testing and how CI helps keep open
source projects well tested.

Topics Include

1:02 – Junaid was running his own online store before making this app
1:38 – Zapier and Google Sheets worked for a while but it wasn’t sustainable
2:12 – Shopify’s API has extensive documentation
2:47 – Drop shipping is a great way to test items before holding your own inventory
4:24 – A lot of these services are trying to compete with Amazon’s fulfillment service
4:37 – Openship lets you transition from drop shipping to having your own inventory
5:24 – Drop shipping and testing items is almost like pre-selling an app idea
5:28 – Junaid hired a contractor early on to help with anything he gets stuck on
5:41 – He didn’t have much luck with StackOverflow early on (I’m not surprised!)

10:11 – Trade offs between working with a mono repo and multi-repo set up
11:32 – Going into a bit more details about the back-end / front-end set up
12:36 – Websockets might be used later when an upcoming messaging system is in place
12:57 – The work flow for adding Openship to your Shopify app
13:10 – Dealing with returns is cumbersome with drop shipping
15:24 – High level recap of the work flow as a shop owner
15:42 – End customers who purchase items see the usual Shopify checkout work flow
16:39 – The marketplace aspect of Openship is very powerful and it’s competitively priced
18:25 – Private labeling is another feature that’s coming soon
18:53 – The marketplace is a separate Shopify shop that uses Shopify’s API
19:06 – The Shopify app is hosted on DigitalOcean using CapRover (self hosted PaaS)
20:04 – Prisma runs on its own server which contains the MySQL database
20:12 – The 2nd server hosts the back-end (web server) and front-end (React app)
20:32 – It was all hosted on 1 server initially but it kept crashing
21:19 – Prisma is an open source CMS for a bunch of popular databases
22:54 – You typically use tools like Apollo to limit access to Prisma
23:19 – The Apollo server prevents anyone from accessing your database
23:50 – What exactly is the Apollo server? It’s a GraphQL implementation
24:34 – Breaking down the layers of your database, Prisma, Apollo and your client
26:22 – Apollo helps deal with multi-tenancy concerns by letting you isolate users
27:06 – Openship doesn’t store any confidential info in their own database
27:55 – Access control between Shopify and Openship is handled with OAuth
28:34 – CapRover handles setting up a reverse proxy and setting up HTTPS
29:31 – Openship isn’t running in Docker but Prisma provided its own Dockerfile
30:35 – CapRover has a bunch of 1 click installers, one of which is for Sentry
30:54 – CapRover is only being used in production
31:42 – Postmark is being used to send transactional emails (free tier)
32:08 – Junaid pays about $10 to $20 a month for Zapier
32:33 – Zapier helps you glue together APIs from external services

37:12 – Dealing with secrets and sensitive values when using CapRover
37:58 – The full break down of how code gets from development to production
38:34 – Running automated tests and the value of CI / CD
40:04 – Get a test suite up and running and then worry about CI
40:52 – TDD vs writing tests after you write your implementation
41:40 – Having a test suite really helps you refactor and improve your code later on
42:06 – The difference between testing locally vs using a continuous integration server
44:27 – The benefits of CI in an open source project for testing pull requests
45:14 – There’s no database backups in place because Shopify is the source of truth

Support the Show

This episode does not have a sponsor and this podcast is a labor of love. If
you want to support the show, the best way to do it is to purchase one of my
courses or suggest one to a friend.

Dive into Docker is a video course that takes you from not knowing what Docker is
to being able to confidently use Docker and Docker Compose for your own apps.
Long gone are the days of "but it works on my machine!". A bunch of follow
along labs are included.

Build a SAAS App with Flask is a video course where we build a real
world SAAS app that accepts payments, has a custom admin, includes high test
coverage and goes over how to implement and apply 50+ common web app features.
There's over 20+ hours of video.
