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,

            }
        });

        //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}`);
    }
}

/**
* Deleting a post
*/
export async function deletePost(c: Context) {
    try {

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

        //delete post with prisma
        await prisma.post.delete({
            where: { id: postId },
        });

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

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

Tahap 2: Penulisan Kode & Konfigurasi

export async function deletePost(c: Context) {

	//...
	
}

Tahap 3: Penulisan Kode & Konfigurasi

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

Tahap 4: Penulisan Kode & Konfigurasi

//delete post with prisma
await prisma.post.delete({
    where: { id: postId },
});

Tahap 5: Penulisan Kode & Konfigurasi

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

Tahap 6: Penulisan Kode & Konfigurasi

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

//import controller
import { getPosts, createPost, getPostById, updatePost, deletePost } 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));

//route post delete
router.delete('/:id', (c) => deletePost(c));

export const Routes = router;

Tahap 7: Penulisan Kode & Konfigurasi

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

Tahap 8: Penulisan Kode & Konfigurasi

//route post delete
router.delete('/:id', (c) => deletePost(c));

Tahap 9: Penulisan Kode & Konfigurasi

{
    "success": true,
    "message": "Post Deleted Successfully!"
}
