    Express Class Validator

    This is a very simple middleware for using simplifying the use of class-validator in express routes.

    It may not be worth installing this package

    Please consider copy-pasting the source from ./lib/index.ts

    Install

    npm i express-class-validator
    

    Usage

    See ./sample/index.ts for a working example (npx ts-node sample/index.ts)

    import { makeValidateBody } from 'express-class-validator'
     
    class User {
        @IsEmail()
        public email!: string
     
        public hello(): string {
            return "World!"
        }
    }
     
    app.post(
        '/user',
        makeValidateBody(User), // Will validate req.body against the User class
        (req, res) => {
            console.info(`Got user:`, req.body)
            console.info(`user.hello():`, req.body.hello())
            res.send(req.body)
        }
    )

    Working Query

    curl -X POST \
      http://localhost:1337/user \
      -H 'Content-Type: application/json' \
      -d '{"email":"bob@bob.com"}'

    Failing Query

    curl -X POST \
      http://localhost:1337/user \
      -H 'Content-Type: application/json' \
      -d '{"email":"NOTANEMAIL"}'

    The makeValidateBody method takes two arguments:

    1. [REQUIRED] Class to validate (using class-validator decorators)
    2. [OPTIONAL] Custom error handler: (err:{}, req, res, next) => void
