[GraphQL](https://graphql.org) implementation for Elixir.
Goals:
- Complete implementation of the [GraphQL Working Draft](https://spec.graphql.org/draft/).
- An idiomatic, readable, and comfortable API for Elixir developers
- Extensibility based on small parts that do one thing well.
- Detailed error messages and documentation.
- A focus on robustness and production-level performance.
Please see the website at [https://absinthe-graphql.org](https://absinthe-graphql.org).
## Why Use Absinthe?
Absinthe goes far beyond GraphQL specification basics.
### Easy-to-Read, Fast-to-Run Schemas
Absinthe schemas are defined using easy-to-read macros that build and verify
their structure at compile-time, preventing runtime errors and increasing
performance.
### Pluggability
The entire query processing pipeline is configurable. Add, swap out, or remove
the parser, individual validations, or resolution logic at will, even on a
per-document basis.
### Advanced Resolution
Absinthe includes a number of advanced resolution features, to include:
- Asynchronous field resolution
- Batched field resolution (addressing N+1 query problems)
- A resolution plugin system supporting further extensibility
### Safety
- Complexity analysis and configurable limiting
- Support for precompiled documents/preventing custom documents
### Idiomatic Documents, Idiomatic Code
Write your schemas in idiomatic Elixir `snake_case` notation. Absinthe can
transparently translate to `camelCase` notation for your API clients.
Or, define your own translation schema by writing a simple adapter.
### Frontend Support
We care about support for third-party frameworks, both on the back and
front end.
So far, we include specialized support for Phoenix and Plug on the backend,
and [Relay](https://relay.dev/) on the frontend.
Of course we work out of the box with other frontend frameworks and GraphQL
clients, too.
## Installation
Install from [Hex.pm](https://hex.pm/packages/absinthe):
```elixir
def deps do
[{:absinthe, "~> 1.7.0"}]
end
```
Note: Absinthe requires Elixir 1.10 or higher.
