![]() If you don't like to see HTML pages when there is an error and instead want to receive Visit and bask in the glory of a beautifully formatted error page.ĭon't worry though, we'll be adding a JSON endpoint soon enough. If you'd like to drop the database for the test environment, you'd need to: MIX_ENV= test mix ecto.drop You can drop the database for the dev environment with: mix ecto.drop If you created a new DB user when installing PostgreSQL, add its credentials toĬonfig/dev.exs and config/test.exs. ![]() If it comes from the database, an external API or others. MyApp keeps the contexts that define your domainĬontexts are also responsible for managing your data, regardless You'll find MyApp used everywhere since it's the main module for your app.įor example in my-app/lib/my_app.ex: defmodule MyApp do """ You'll see my_app used in files and directories inside my-app/lib e.g. You'll see my-app as the name for the directory created for this application. In your terminal: mix phx.new my-app -app my_app -module MyApp -no-brunch -no-html I'll show you some examples on how to test out your endpoints from the CLI.Ĭreate a new API-only Phoenix application Generate the app files Or you can just use good ol' curl it works really well! This will allow the client to send cookies along when doing CORS requests. If you go with Axios dont' forget to pass the configuration option withCredentials: true, If you are using a web frontend library like Axios, then yourīrowser's developer tools should be enough: Incarnations- as one didn't display cookie info, and the other didn't send Tested both of them and I can say liked neither -at least on their Chrome app The two most popular ones seem to be Postman and Advanced Rest Client I You might need to get a REST client so you can try out your API endpoints. ![]() How to install PostgreSQL in Manjaro Linux.It's a solid, realiable, and well engineered relational DB. PostgreSQL is the default database for new Phoenix apps, and with good reason: How to install Elixir in Manjaro Linux.Manager -using version managers is a best practice in development environments. We will start by installing Erlang and Elixir using the asdf version Implement a JSON API with Elixir / Phoenix. This is the tutorial I wish I had available when I was trying to learn about how to I'm just starting with Elixir / Phoenix, if there are any omissions or bad practices,īear with me, notify me and I'll fix them ASAP. If you are interested on doing auth with JWTs, check this other tutorial out. Create a Sign in endpoint -using session based authentication through cookies.CORS configuration -so you can use that frontend of yours that runs on.Create a Users endpoint -so you can get a list of, create or delete users!.Create a User schema module and hash its password -because storing plain text.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 That's easy enough, you just need to pass the -no-brunch -no-html 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 Going from zero to fully working prototype without skipping steps. Scoped, focused tutorials, should be used to explain techniques, like this one:īut, full step-by-step tutorials should be used to teach about new tech stacks. I have found there are mainly two types of tutorials one should write: Postgrex comes with JSON support out of the box via the Jason library.Original publication at: lobo_tuerto's notesĪre you tired of looking at outdated or incomplete tutorials on how toīuild a JSON API using Elixir and Phoenix? To add type casting, support new types, or change how any of the types above are encoded/decoded, you can use extensions. For example, you can't pass a string where a date is expected. Postgrex does not automatically cast between types. **** Anonymous composite types are decoded (read) as tuples but they cannot be encoded (written) to the database *** Enumerated types (enum) are custom named database types with strings as values. ** Timezones will always be normalized to UTC or assumed to be UTC when no information is available, either by PostgreSQL or Postgrex
