These libraries provides a family of combinators to define webservices and
|
|
automatically generate the documentation and client-side querying functions for
|
|
each endpoint.
|
|
|
|
In order to minimize the dependencies depending on your needs, we provide these
|
|
features under different packages.
|
|
|
|
- `servant`, which contains everything you need to *declare* a webservice API.
|
|
- `servant-server`, which lets you *implement* an HTTP server with handlers for
|
|
each endpoint of an API.
|
|
- `servant-client`, which lets you derive automatically Haskell functions that
|
|
let you query each endpoint of a `servant` webservice.
|
|
- `servant-docs`, which lets you generate API docs for your webservice.
|
|
- `servant-js`, which lets you derive Javascript functions (using vanilla JS
|
|
ajax requests, angular or jquery) to query your API's endpoints, in the same
|
|
spirit as `servant-client`.
|
|
- `servant-blaze` and `servant-lucid` provide easy HTML rendering of your data
|
|
as an `HTML` content-type "combinator".

## Tutorial
|
|
|
|
We have a [tutorial](http://haskell-servant.github.io/tutorial) guide that
|
|
introduces the core types and features of servant. After this article, you
|
|
should be able to write your first servant webservices, learning the rest from
|
|
the haddocks' examples.

## Contributing
|
|
|
|
Contributions are very welcome! To hack on the github version, clone the
|
|
repository. You can use `cabal`:
|
|
|
|
```shell
|
|
./scripts/start-sandbox.sh # Initialize the sandbox and add-source the packages
|
|
./scripts/test-all.sh # Run all the tests
|
|
```
|
|
|
|
`stack`:
|
|
|
|
```shell
|
|
stack build # Install and build packages
|
|
stack test # Run all the tests
|
|
```
|
|
|
|
Or `nix`:
|
|
```shell
|
|
./scripts/update-nix-files.sh # Get up-to-date shell.nix files
|
|
```
|
|
|
|
Though we aren't sticklers for style, the `.stylish-haskell.yaml` and `HLint.hs`
|
|
files in the repository provide a good baseline for consistency.
|
|
|
|
Please include a description of the changes in your PR in the `CHANGELOG.md` of
|
|
the packages you've changed. And of course, write tests!
