In this post, we'll configure a Phoenix LiveView application to use a structured logger. We'll then use AppSignal to correlate log events with other telemetry signals, like exception reports and traces. Along the way, you'll learn about the benefits of structured logging, and you'll see how to configure a distinct framework and application logger in your Phoenix app. Let's get started!
In the last two posts of this series, we saw how easy it is to integrate Absinthe into your app to provide a GraphQL API for querying data. We also shared some useful tips for building and maintaining large schemas and optimizing queries. This post will show how we can provide an API to create GraphQL mutations with Absinthe for Elixir. Let's get started!
Phoenix 1.7 came out this year with a whole host of exciting features, including verified routes and some great built-in Tailwind components. These components are a fantastic start, but they are not made to be a fully general design system. We should expect to modify components to fit our specific needs. However, knowing where to start can be difficult. In this three-part series, we'll take a fresh Phoenix app and create a working UI using generated components.
In our introduction to Absinthe, we covered the basics of Absinthe and GraphQL for an Elixir application. Now we'll dig deeper and see how we can customize Absinthe for larger-scale Elixir applications. Let's get going!
Ecto can be considered the standard database wrapper and query generator for Elixir, enabling developers to interact with databases efficiently. However, inefficient queries or misconfigurations still can (and will) happen. Addressing these issues is crucial for a smooth user experience.
In part one of this series, we introduced Elixir test factories and fixtures. Then in part two, we explored using data generation functions. Now we'll look at some of the best Elixir libraries to use for your test data. But before we do, let's quickly discuss why test data libraries can be helpful.
A well-written test suite is a big part of any successful application. But let's say you rely on an external dependency for some parts of your app (for example, an external API for fetching user information). It then becomes important to mock that dependency in the test suite to prevent external API calls during testing or to test specific behavior. Several frameworks help reduce the boilerplate and make mocking safe for Elixir tests.
In this blog post, you'll see how useful open_browser/2 is when debugging LiveView tests. In addition, we'll give a brief introduction to testing LiveView. Let's get started!
In the first part of this series, we explored the ins and outs of Elixir test factories and fixtures. However, test factories bypass the rules of your Elixir application. Let's turn our attention to how we can avoid this by using data generation functions. Let's dive straight in!
Writing tests is an essential part of any Elixir developer's routine. We're constantly chasing knowledge on how to write better tests, improving their speed and readability. In this three-part series, we'll explore test data generation in Elixir. Whether you are a mid-level or senior-level Elixir developer, this series will provide valuable insights to help improve the testing process for your projects.
