Code sharing module between different services

Which consists of middleware, events, types, error classes, etc.

The middleware validateRequest and RequestValidationError error classes are used for the express-validator node module.

import { body } from "express-validator";
import { validateRequest, BadRequestError } from "@ergool/common";

router.post(
  "/v2/auth/signin",
  [
    body("email").isEmail(),
    body("password").trim().notEmpty(),
  ],
  validateRequest,
  async (req: Request, res: Response) => {
    .
    .
    .

    if (somethingWrong) throw new BadRequestError("😟");

    .
    .
    .
    res.status(200).send();
  }
);

The middleware yupValidateRequest and YupRequestValidationError error classes are used for the yup node module.

import * as yup from "yup";
import { yupValidateRequest, BadRequestError } from "@ergool/common";

const schema = yup.object().shape({
  body: yup.object({
    email: yup
      .string()
      .label("Email")
      .email()
      .required(),
    password: yup
      .string()
      .trim()
      .label("Password")
      .required(),
  }),
});

router.post(
  "/v2/auth/signin",
  yupValidateRequest(schema),
  async (req: Request, res: Response) => {
    .
    .
    .

    if (somethingWrong) throw new BadRequestError("😟");

    .
    .
    .
    res.status(200).send();
  }
);
