Writing Simple RestAPI in Nim With HappyX #3

Hi there 👋!

Previously we add posts getting 🙂.

Now we implement post adding ✌.

At first go into src/main.nim and add Request Model

import
  # This will import HappyX framework
  happyx

# Request model AddPost
# with two string fields
model AddPost:
  title: string
  text: string

After this let's create post addition method 🍍

  # on POST HTTP method at 127.0.0.1:5000/post/
  post "/post/[postData:AddPost]":

Here we use AddPost as postData immutable var 🎈

Let's add sended post into posts variable

  # on POST HTTP method at 127.0.0.1:5000/post/
  post "/post/[postData:AddPost]":
    posts.add(%*{
      "title": postData.title,
      "text": postData.text
    })

Here we convert AddPost model to JsonNode object and add it into our posts

Let's says user about post successfully added into our posts ✨
Just add return statement

  # on POST HTTP method at 127.0.0.1:5000/post/
  post "/post/[postData:AddPost]":
    posts.add(%*{
      "title": postData.title,
      "text": postData.text
    })
    return {"response": {
      "index": posts.len - 1
    }}

You can test it into postman ✌
URL: http://localhost:5000/post/
Method: POST
JSON raw body:

{"title": "Your title", "text": "your text"}

And try to open http://localhost:5000/posts after adding post 👀

That's all! Good luck ✨
