打字稿导致找不到模块错误

我正在尝试构建基本的Express api,并遇到一个奇怪的module not found错误。在将TypeScript引入我的项目之前,我从未遇到此错误。解决这个问题非常令人沮丧。感谢您提出有关为什么出现此错误以及如何解决的任何建议。

server.ts

import express from "express";
import cors from "cors";
import bodyParser from "body-parser";
//import * as api from "api"; also tried this

const app = express();

app.use(cors());
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extended:false}));

app.use('/api', require('./api'));

app.use('*', (req, res, next) => {
    let error = new Error('404: not found');
    next(error);
});

app.use((error, req, res, next) => {
    res.status(500).send({
        error: {
            message: error.message
        }
    });
});

const port = 3000;

app.listen(port, () => {
    console.log('listening on port', port);
});

module.exports = app;

api / api.ts

import express from "express";

const router = express.Router();

router.use('/', (req, res, next) => {
   res.send('cool');
});

module.exports = router;

使用打字稿,我们不使用module.exports,而是像这样直接导出:

import express from "express";

export const router = express.Router();

router.use('/', (req, res, next) => {
   res.send('cool');
});

然后我们可以使用

import {router} from './api'
