```
or
```bash
$ npm install --save bs-axios
```
2. Add "bs-axios" to "bs-dependencies" section of `bsconfig.json`
## Examples
See usage examples in examples folder:
- [Request examples](./examples/request_examples.re) (GET, POST)
- [Instance example](./examples/instance_example.re)
### Simple request
```reason
Js.Promise.(
Axios.get("/user?ID=12345")
|> then_((response) => resolve(Js.log(response##data)))
|> catch((error) => resolve(Js.log(error)))
);
```
### Post requests
```reason
Js.Promise.(
Axios.post("/user")
|> then_((response) => resolve(Js.log(response##data)))
|> catch((error) => resolve(Js.log(error)))
);
```
```reason
let user = {
"username": "michel",
"password": "12345678"
};
Js.Promise.(
Axios.postData("/auth", {user})
|> then_((response) => resolve(Js.log(response##data)))
|> catch((error) => resolve(Js.log(error)))
);
```
### Concurrency
```reason
Js.Promise.(
Axios.all2((Axios.get("/users/1"), Axios.get("/users/1/friends")))
|> then_(((user, friends)) => resolve(Js.log2(user##data, friends##data)))
|> catch((error) => resolve(Js.log(error)))
);
```
### Creating an instance
You can create a new instance of axios with a custom config.
```reason
open Axios;
let inst = Instance.create(makeConfig(~baseURL="https://example.com", ()));
Js.Promise.(Instance.get(inst, "/") |> then_((resp) => resolve(Js.log(resp##data))));
```
### Error handling
```reason
external promiseErrorToJsObj : Js.Promise.error => Js.t('a) = "%identity";
Js.Promise.(
Instance.get(inst, "/")
|> then_(resp => resolve(Belt.Result.Ok(resp)))
|> catch(error => {
let error = error |> promiseErrorToJsObj;
Js.log(error##response##status);
resolve(Belt.Result.Error(error));
})
);
```
### Headers
```reason
let headers = Axios.Headers.fromObj({"Content-type": "application/json"});
Axios.getc("https://example.com", Axios.makeConfig(~headers, ()));
let headersDict =
Js.Dict.(
{
let dict = empty();
dict->set("Content-type", "application/json");
dict;
}
);
let headers = Axios.Headers.fromDict(headersDict);
Axios.getc("https://example.com", Axios.makeConfig(~headers, ()));
```
### Node.js HTTP/HTTPS Agent
Providing custom Node.js [`HTTP Agent`](https://nodejs.org/api/http.html#http_class_http_agent)
allows for configuring connection persistence and reuse. For secure connections,
[`HTTPS Agent`](https://nodejs.org/api/https.html#https_class_https_agent) allows security related
configuration to be provided.
```reason
let httpsAgent =
Axios.Agent.Https.(config(~rejectUnauthorized=false, ()) |> create);
Axios.getc(
"https://insecure-example.com",
Axios.makeConfig(~httpsAgent, ()),
);
```
