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;
答案 0 :(得分:1)
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'
