Typescript 节点表示路由器和第二个参数。Typescript-eslint/无滥用承诺

Question

我应该如何处理注册功能来修复@typescript-eslint/no-misused-promises。我发现解决这个问题的一种方法是通过 eslint 编写。

"@typescript-eslint/no-misused-promises": [
  "error",
  {
    "checksVoidReturn": false
  }
]

但我想按照 eslint 的要求解决这个问题。有任何想法吗？

import PromiseRouter from "express-promise-router";
import { login, registration } from './authController';

const router = PromiseRouter();


> ESLint: Promise returned in function argument where a void return was
> expected.(@typescript-eslint/no-misused-promises)

router.post('/registration', registration);

这是注册的完整功能

export async function registration(req: TreqBodyReg, res: Response): Promise<void> {
  try {
    const { email, password } = req.body;
    const candidate = await ModelUser.findOne({ email }) as TuserFromDB;
    if (candidate) {
      res.status(400).json({ message: `There is user with email ${email}` });
      return;
    }
    const hashPassword = bcrypt.hashSync(password, 7);
    const user = new ModelUser({ email, password: hashPassword });
    await user.save();
    res.status(200).json({ message: `The user by email ${email} was successfully registered` });
  } catch (err: unknown) {
    res.status(400).json({ message: err });
  }
};

这是迂回的，但我通过这种方式解决了问题。

async function registerUser(req: TreqBodyReg, res: Response): Promise<void> {
  const { email, password } = req.body;
  const candidate = await ModelUser.findOne({ email }) as TuserFromDB;
  if (candidate) {
    res.status(400).json({ message: `There is user with email ${email}` });
    return;
  }
  const hashPassword = bcrypt.hashSync(password, 7);
  const user = new ModelUser({ email, password: hashPassword });
  await user.save();
  res.status(200).json({ message: `The user by email ${email} was successfully registered` });
}

export function registration(req: TreqBodyReg, res: Response): void {
  registerUser(req, res).catch((err: unknown) => {
    res.status(400).json({ message: err });
  });
}
