Membangun aplikasi web di era modern memerlukan pondasi yang kokoh. Framework modern memberikan fleksibilitas luar biasa bagi developer untuk menghadirkan fitur kompleks secara cepat tanpa mengabaikan aspek keamanan dan keandalan sistem.

Tahapan Implementasi & Walkthrough Kode

Berikut adalah langkah demi langkah teknis yang dapat Anda ikuti langsung pada codebase Anda:

Tahap 1: Penulisan Kode & Konfigurasi

//import context
import { Context } from 'hono'

//import prisma client
import prisma from "../../prisma/client";

/**
 * Getting all posts
 */
export const getPosts = async (c: Context) => {
    try {
        //get all posts
        const posts = await prisma.post.findMany({ orderBy: { id: 'desc' } });

        //return JSON
        return c.json({
            success: true,
            message: 'List Data Posts!',
            data: posts
        }, 200);

    } catch (e: unknown) {
        console.error(`Error getting posts: ${e}`);
    }
}

/**
 * Creating a post
 */
export async function createPost(c: Context) {
    try {

        //get body request
        const body = await c.req.parseBody();

        //check if title and content is string
        const title = typeof body['title'] === 'string' ? body['title'] : '';
        const content = typeof body['content'] === 'string' ? body['content'] : '';

        //create post
        const post = await prisma.post.create({
            data: {
                title: title,
                content: content,
            }
        });

        //return JSON
        return c.json({
            success: true,
            message: 'Post Created Successfully!',
            data: post
        }, 201);

    } catch (e: unknown) {
        console.error(`Error creating post: ${e}`);
    }

}

/**
* Getting a post by ID
*/
export async function getPostById(c: Context) {
    try {

        // Konversi tipe id menjadi number
        const postId = parseInt(c.req.param('id'));

        //get post by id
        const post = await prisma.post.findUnique({
            where: { id: postId },
        });

        //if post not found
        if (!post) {
            //return JSON
            return c.json({
                success: false,
                message: 'Post Not Found!',
            }, 404);
        }

        //return JSON
        return c.json({
            success: true,
            message: `Detail Data Post By ID : ${postId}`,
            data: post
        }, 200);

    } catch (e: unknown) {
        console.error(`Error finding post: ${e}`);
    }
}

/**
 * Updating a post
 */
export async function updatePost(c: Context) {
    try {

        // Konversi tipe id menjadi number
        const postId = parseInt(c.req.param('id'));

        //get body request
        const body = await c.req.parseBody();

        //check if title and content is string
        const title = typeof body['title'] === 'string' ? body['title'] : '';
        const content = typeof body['content'] === 'string' ? body['content'] : '';

        //update post with prisma
        const post = await prisma.post.update({
            where: { id: postId },
            data: {
                title: title,
                content: content,
                updatedAt: new Date(),
            },
        });

        //return JSON
        return c.json({
            success: true,
            message: 'Post Updated Successfully!',
            data: post
        }, 200);

    } catch (e: unknown) {
        console.error(`Error updating post: ${e}`);
    }
}

Tahap 2: Penulisan Kode & Konfigurasi

export async function updatePost(c: Context) {

	//...
	
}

const title = typeof body['title'] === 'string' ? body['title'] : '';
const content = typeof body['content'] === 'string' ? body['content'] : '';

Tahap 6: Penulisan Kode & Konfigurasi

//update post with prisma
const post = await prisma.post.update({
    where: { id: postId },
    data: {
        title: title,
        content: content,
        updatedAt: new Date(),
    },
});

Tahap 7: Penulisan Kode & Konfigurasi

//return JSON
return c.json({
    success: true,
    message: 'Post Updated Successfully!',
    data: post
}, 200);

Tahap 8: Penulisan Kode & Konfigurasi

//import hono
import { Hono } from 'hono';

//import controller
import { getPosts, createPost, getPostById, updatePost } from '../controllers/PostController';

//inistialize router
const router = new Hono()

//routes posts index
router.get('/', (c) => getPosts(c));

//routes posts create
router.post('/', (c) => createPost(c));

//routes posts detail
router.get('/:id', (c) => getPostById(c));

//route post update
router.patch('/:id', (c) => updatePost(c));

export const Routes = router;

Tahap 9: Penulisan Kode & Konfigurasi

//import controller
import { getPosts, createPost, getPostById, updatePost } from '../controllers/PostController';

Tahap 10: Penulisan Kode & Konfigurasi

//route post update
router.patch('/:id', (c) => updatePost(c));

Tahap 11: Penulisan Kode & Konfigurasi

{
    "success": true,
    "message": "Post Updated Successfully!",
    "data": {
        "id": 1,
        "title": "Belajar Bun dan Hono di SantriKoding - Edit",
        "content": "Belajar Bun dan Hono di SantriKoding - Edit",
        "createdAt": "2024-05-14T03:02:08.341Z",
        "updatedAt": "2024-05-14T05:47:25.919Z"
    }
}
