naboris

Simple, fast, minimalist web framework for [OCaml](https://ocaml.org)/[ReasonML](https://reasonml.github.io) built on [httpaf](https://github.com/inhabitedtype/httpaf) and [lwt](https://github.com/ocsigen/lwt).

### Installation

#### Note
Naboris makes heavy use of [Lwt](https://github.com/ocsigen/lwt#installing). For better performance it is highly recommended _(however optional)_ to also install `conf-libev` which will configure [Lwt](https://github.com/ocsigen/lwt#installing) to run with the libev scheduler. If you are using **esy** you will have to install `conf-libev` using a [special package](https://github.com/esy-packages/libev).

`conf-libev` also requires that the libev be installed. This can usually be done via your package manager.
```bash
brew install libev
```
or
```bash
apt install libev-dev
```

#### opam
```bash
opam install naboris
```

#### esy
```json
"@opam/naboris": "^0.1.3"
```

#### dune
```
(libraries naboris)
```

### Scaffolding
For a basic Reason project
```bash
git clone [email protected]:shawn-mcginty/naboris-re-scaffold.git
cd naboris-re-scaffold
npm run install
npm run build
npm run start
```

For a basic OCaml project
```bash
git clone [email protected]:shawn-mcginty/naboris-ml-scaffold.git
cd naboris-ml-scaffold
npm run install
npm run build
npm run start
```

## Development
Any help would be greatly appreciated! 👍

### To run tests

```bash
esy install
npm run test
```

## Breaking Changes

| From | To | Breaking Change |
| --- | --- | --- |
| `0.1.2` | `0.1.3` | `secret` argument added to all session configuration APIs. |
| `0.1.0` | `0.1.1` | `ServerConfig.setSessionGetter` changed to `ServerConfig.setSessionConfig` which also allows `~maxAge` and `~sidKey` to be passed in optionally. |
| `0.1.0` | `0.1.1` | All `RequestHandler.t` and `Middleware.t` now return `Lwt.t(Res.t)` instead of `Lwt.t(unit)` |
| `0.1.0` | `0.1.1` | `Res.reportError` now taxes `exn` as the first argument to match more closely the rest of the `Res` API. |
