Way to parse body, params, and query in Nodejs using Zod

express_zod_validator.ts

import express, { Request, Response } from 'express';
import z, { AnyZodObject, ZodError } from 'zod';
import { generateError } from 'zod-error';

const app = express();

const mySchema = z.object({
    body: z.object({
        name: z.string(),
    }),
    params: z.object({
        id: z.string(),
    }),
});

export async function zParse<T extends AnyZodObject>(
    schema: T,
    req: Request,
    res: Response,
): Promise<z.infer<T>> {
    try {
        return schema.parseAsync(req);
    } catch (error) {
        throw error;
    }
}

app.all('/', async (req, res) => {
    try {
        const payload = await zParse(mySchema, req, res);
        res.json(payload);
    } catch (error) {
        if (error instanceof ZodError) {
            const errors = generateError(error);
            return res.status(400).json({ error: errors });
        }
        return res.status(500).json({ error: 'Internal Server Error' });
    }
});

const PORT = process.env.PORT || 5001;
app.listen(PORT, () => {
    console.log(`Server running on port ${PORT}`);
});
