Indium is a dead simple backend library inspired by Express and powered by Lune

It aims to provide you with all the convenient tools to reduce pain while remaining lightweight.

Installation

Either clone repository or use pesde:

pesde add intervinn/indium

Quick Example

local Indium = require("Package")

local app = Indium.App.new()

-- middleware
app.router:use(function(req, res, next)
    print(req.method, req.path)
    next()
end)

-- routing
app.router:get("/", function(req, res)  
    res:status(200):json({
        message = "hello, world"
    })
end)

-- serving
app:listen(8080, function()  
    print("up")
end)

Dynamic routing is also available:

local Indium = require("../..")

local users = Indium.Router.new()
users:get("/:username", function(req, res)
    res:status(200):json({
        message = `you might be looking for {req.params.username}`
    })
end)

local app = Indium.App.new()
app.router:mount(users, "/users")

app.router:get("/", function(req, res)
    res:status(200):json({
        message = "hello, world"
    })
end)

app:listen(8080, function()
    print("up")
end)

Some middleware can improve your experience:

local Indium = require("../..")

local app = Indium.App.new()

app.router:use(Indium.Middleware.Logger.new())
app.router:use(Indium.Middleware.CORS.new({
    origin = "*"
}))

app:listen(8080, function()
    print("up")
end)

You can split some of your code into separate routers, and then unite them all:

local Indium = require("../..")

local users = Indium.Router.new()
users:get("/:username", function(req, res)
    res:status(200):json({
        message = `you might be looking for {req.params.username}`
    })
end)

local app = Indium.App.new()
app.router:mount(users, "/users")

app.router:get("/", function(req, res)
    res:status(200):json({
        message = "hello, world"
    })
end)

app:listen(8080, function()
    print("up")
end)

It's raw and needs improvements, contributions would be welcome
