Lib.rs

Web server runtime for Lua (5.1-5.4), Luau and LuaJIT written in Rust. The goal is to get as much performance as possible while writing the web server logic in Lua instead for faster iteration, fault-tolerance and no-build requirements. This project is internally used here at ArkForge and many others.

Installation

You can either get the binaries at github releases or using cargo if you have it installed:

cargo install lua-astra

Example

Typically in Astra you can register routes like below, binded to a method

Astra:get("/", function()
    return "hello from default Astra instance!"
end)

and starting the server with

Astra:run()

You can also use the local variables within routes

local counter = 0
Astra:get("/count", function()
    counter = counter + 1
    -- and also can return JSON
    return { counter }
end)

Requests and Responses and their configuration are provided when needed

Astra:get("/", function(req, res)
    -- set header code
    res:set_status_code(300)
    -- set headers
    res:set_header("header-key", "header-value")

    -- consume the request body
    print(req:body():text())

    return "Responding with Code 300 cuz why not"
end)

There are also utilities provided such as a PostgreSQL, http client requests, lua extra utils, and async tasks.

-- spawn an async task that does not block the running thread
spawn_task(function ()
    -- HTTP Request to check your IP address
    local response = http_request("https://myip.wtf/json"):execute()
    pretty_print(response:status_code())
    pretty_print(response:remote_address())
    pretty_print(response:body():json())
end)

Note

This project may have breaking changes in minor versions until v1.0. Afterwhich semver will be followed. Contributions are always welcome!
