![]() ![]() The documentation suggests that you create Using the sequence function automatically avoids uniqueĭatabase constraint issues when calling the same factory multiple times.ĮxMachina also lets you add more building strategies, such as a JSON strategy that It simplifies the caller's job by eliminating the need Guarantees you'll get the next increment of a sequence each time you call it, and the One of the most powerful features of ExMachina is the sequence function, which ![]() The factory library ExMachina created by Thoughbot uses function names and generates an atom used to call factories. Let's start with the most famous one: ExMachina. We'll look at ExMachina, ExZample, Faker, and StreamData. Libraries and why you might want to use them. Here's a quick overview of existing test data ![]() However, existing test data libraries are convenient as you don't have to write them yourself. Why Choose a Test Data Library for Your Elixir App?īuilt-in language features are more than sufficient for writing simple helpers to buildįor example, refer to the Ecto Guide to write a factory method pattern API like the one provided Now we'll look at some of the best Elixir libraries to use for your test data.īut before we do, let's quickly discuss why test data libraries can be helpful. Then in part two, we explored using data generation functions. I’ll show you some examples on how to test out your endpoints from the CLI.In part one of this series, we introduced Elixir test factories and fixtures. ![]() Or you can just use good ol’ curl it works really well! If you go with Axios dont’ forget to pass the configuration option withCredentials: true, this will allow the client to send cookies along when doing CORS requests. If you are using a web frontend library like Axios, then your browser’s developer tools should be enough: The two most popular ones seem to be Postman and Advanced Rest Client I tested both of them and I can say liked neither -at least on their Chrome app incarnations- as one didn’t display cookie info, and the other didn’t send declared variables on POST requests. You might need to get a REST client so you can try out your API endpoints. How to install PostgreSQL in Manjaro Linux.PostgreSQL is the default database for new Phoenix apps, and with good reason: It’s a solid, realiable, and well engineered relational DB. Let’s take on Hex the package manager now:Įnter fullscreen mode Exit fullscreen mode How to install Elixir in Manjaro Linux.We will start by installing Erlang and Elixir using the asdf version manager -using version managers is a best practice in development environments. This is the tutorial I wish I had available when I was trying to learn about how to implement a JSON API with Elixir / Phoenix, but I digress. I’m just starting with Elixir / Phoenix, if there are any omissions or bad practices, bear with me, notify me and I’ll fix them ASAP. I can do a JWT one later if enough people are interested. Create a Sign in endpoint -using session based authentication.CORS configuration -so you can use that frontend of yours that runs on another port / domain.Create a Users endpoint -so you can get a list of, create or delete users!.Create a User schema module (model) and hash its password -because storing plain text passwords in the database is just wrong.Create a new API-only Phoenix application -skip HTML and JS stuff.Quickstart guide for a new Vue.js project. To complement your API, I recommend Vue.js on the frontend: This tutorial is about creating a small, but fully operational JSON API for web applications. That’s easy enough, you just need to pass the -no-brunch -no-htmlto mix phx.new. So, this won’t just be about how to generate a new Phoenix API only app. I really like tutorials that take this holistic approach. With best practices baked-in, presenting the best libreries available for a given task. Going from zero to fully working prototype without skipping steps. Scoped, focused tutorials, should be used to explain techniques, like this one: Fluid SVGs with Vue.js.īut, fully-integrated tutorials should be used to teach about new tech stacks. I have found there are mainly two types of tutorials one should write: )Īre you tired of looking at outdated or incomplete tutorials on how to build a JSON API using Elixir and Phoenix? It also includes a content table for easy navigation over there. You can check the latest updated version of this article at lobotuerto's notes - Building a JSON API with Phoenix 1.3 and Elixir. ![]()
