'require() of ES modules is not supported. ' error with Node.js, express, swagger-jsdoc
I solved this issue with downgrade swagger-jsdoc to 6.0.0
So, my package.json file now look like:
{
"name": "swaggertest",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"start": "nodemon app.js",
"test": "echo \"Error: no test specified\" && exit 1"
},
"keywords": [],
"author": "",
"license": "ISC",
"dependencies": {
"express": "^4.17.1",
"nodemon": "^2.0.7",
"swagger-jsdoc": "6.0.0",
"swagger-ui-express": "^4.1.6"
}
}

I trying to import swagger-jsdoc but I get an error. I searched on internet but other solutions not work for me.
My server.js file like that:
const express = require('express'); const app = express(); const swaggerJsDoc = require('swagger-jsdoc'); const port = 3000; app.get('/customers', (req,res) => { res.send('Customers Route'); }) app.listen(port, ()=> { console.log('Server listening on 3000'); })
And my package.json file like that:
{ "name": "swaggertest", "version": "1.0.0", "description": "", "main": "index.js", "scripts": { "start": "nodemon app.js", "test": "echo \"Error: no test specified\" && exit 1" }, "keywords": [], "author": "", "license": "ISC", "dependencies": { "express": "^4.17.1", "nodemon": "^2.0.7", "swagger-jsdoc": "^7.0.0-rc.4", "swagger-ui-express": "^4.1.6" } }
But when I try to run this project with "npm start" I getting this error:
node:internal/modules/cjs/loader:1108 throw new ERR_REQUIRE_ESM(filename, parentPath, packageJsonPath); ^
Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: /Users/me/Desktop/Projects/swaggertest/node_modules/swagger-jsdoc/index.js require() of ES modules is not supported. require() of /Users/me/Desktop/Projects/swaggertest/node_modules/swagger-jsdoc/index.js from /Users/me/Desktop/Projects/swaggertest/app.js is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules. Instead rename index.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from /Users/me/Desktop/Projects/swaggertest/node_modules/swagger-jsdoc/package.json. ... code: 'ERR_REQUIRE_ESM' ...
How can I solve this issue?
