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, pub post_id: X, score: X, auth: X, }' \ /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}` ### User / Authentication / Admin actions #### Login The `jwt` string should be stored and used anywhere `auth` is called for. ##### Request ```rust { op: "Login", data: { username_or_email: String, password: String } } ``` ##### Response ```rust { op:
