expressjsHow do I use Zod with Express.js?
Zod is a JavaScript library that can be used to validate data in Express.js applications. It provides a powerful type system, allowing developers to easily validate and transform data.
Using Zod with Express.js is easy. Here's an example of how to use Zod to validate a request body:
const { zod } = require('zod');
const schema = zod.object({
name: zod.string(),
age: zod.number()
});
app.post('/', (req, res) => {
const { body } = req;
const { errors, data } = schema.parse(body);
if (errors) {
// handle errors
} else {
// use data
}
});
In the example above:
- The
zod
object is imported from thezod
library. - A Zod schema is defined, specifying that the request body should contain a
name
field of typestring
and anage
field of typenumber
. - The request body is parsed using the
schema.parse()
method. - If there are any validation errors, they are handled. Otherwise, the data is used as needed.
For more information on using Zod with Express.js, check out the official documentation.
