HI Team,
I am trying to create a calculator app in julia with Genie web framwork for API , but I am getting below error

using Genie, Genie.Router, Genie.Renderer.Json

# Load the separate modules
include("src/addition.jl")
include("src/subtraction.jl")

using .Addition
using .Subtraction

# Define API routes

route("/add/:a/:b", method="POST") do
    a = parse(Int, params(:a))
    b = parse(Int, params(:b))
    result = add(a, b)
    Json(json(:result => result))
end

route("/subtract/:a/:b", method="GET") do
    a = parse(Int, params(:a))
    b = parse(Int, params(:b))
    result = subtract(a, b)
    Json(json(:result => result))
end

# Start the Genie server
Genie.config.run_as_server = true
Genie.Server.up()
#GenieAppServer.startup()

#Genie.config.run_as_server = true  # Make sure the app runs as a server
#Genie.startup()  # This starts the Genie application

Addition file

module Addition

export add

function add(a::Int, b::Int)
    return a + b
end

end # module

error below

500 Internal Error - UndefVarError: `add` not defined

Have you looked into Oxygen.jl?

Here is example from Oxygen.jl

using Oxygen
using HTTP

@get "/add/{x}/{y}" function(request::HTTP.Request, x::Int, y::Int)
    x + y
end

# start the web server
serve()
