## Data types
- `i16`, `i32` and `i64` are respectively [16-bit](https://en.wikipedia.org/wiki/16-bit), [32-bit](https://en.wikipedia.org/wiki/32-bit) and [64-bit](https://en.wikipedia.org/wiki/64-bit_computing) integers.
- Option<***SomeType***> designates an option which may be omitted in requests and not be present in responses. It will be of type ***SomeType***.
- Vec<***SomeType***> is a list which contains objects of type ***SomeType***.
- `chrono::NaiveDateTime` is a timestamp string in [ISO 8601](https://en.wikipedia.org/wiki/ISO_8601) format. Timestamps will be UTC.
- Other data types are listed [here](../server/src/db).
## Basic usage
Request and response strings are in [JSON format](https://www.json.org).
### WebSocket
Connect to ws://***host***/api/v1/ws to get started.
If the ***`host`*** supports secure connections, you can use wss://***host***/api/v1/ws.
#### Testing with Websocat
[Websocat link](https://github.com/vi/websocat)
`websocat ws://127.0.0.1:8536/api/v1/ws -nt`
A simple test command:
`{"op": "ListCategories"}`
#### Testing with the WebSocket JavaScript API
[WebSocket JavaScript API](https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API)
```javascript
var ws = new WebSocket("ws://" + host + "/api/v1/ws");
ws.onopen = function () {
console.log("Connection succeed!");
ws.send(JSON.stringify({
op: "ListCategories"
}));
};
```
### HTTP
Endpoints are at http://***host***/api/v1/***endpoint***. They'll be listed below for each action.
#### Testing with Curl
##### Get Example
```
curl /community/list?sort=Hot
```
##### Post Example
```
curl -i -H \
"Content-Type: application/json" \
-X POST \
-d '{
"comment_id": X,
"post_id": X,
"score": X,
"auth": "..."
}' \
/comment/like
```
## Rate limits
- 1 per hour for signups and community creation.
- 1 per 10 minutes for post creation.
- 30 actions per minute for post voting and comment creation.
- Everything else is not rate-limited.
## Errors
```rust
{
op: String,
message: String,
}
```
## API documentation
### Sort Types
These go wherever there is a `sort` field. The available sort types are:
- `Hot` - the hottest posts/communities, depending on votes, views, comments and publish date
- `New` - the newest posts/communities
- `TopDay` - the most upvoted posts/communities of the current day.
- `TopWeek` - the most upvoted posts/communities of the current week.
- `TopMonth` - the most upvoted posts/communities of the current month.
- `TopYear` - the most upvoted posts/communities of the current year.
- `TopAll` - the most upvoted posts/communities on the current instance.
### Websocket vs HTTP
- Below are the websocket JSON requests / responses. For HTTP, ignore all fields except those inside `data`.
- For example, an http login will be a `POST` `{username_or_email: X, password: X}`
