[SOLVED] Adminjs implementation issue "Cannot use import statement outside a module"

Adminjs implementation issue "Cannot use import statement outside a module"

I'm new in node express js. Just trying to writting the backend code using express js. Now I want to add adminjs in my project. As I'm new in this section, I've followed the official documentation of adminjs express plugin https://docs.adminjs.co/installation/plugins/express

But I'm facing issue while running app.js

import AdminJSExpress from '@adminjs/express'
^^^^^^

Node.js v21.5.0

I have gone through the chatGPT. it suggest me to add "type": module in package.json. but I don't want to change it to module. I also don't want to use typescript

I just want to add admin panel in my existing project which is frogbase using express.js and postgresql

If you want you can also checkout the github repository https://github.com/frogbase/frogbase

Solution

I don't use @adminjs/express so not 100% sure this will work for you but looking at its ES export from npm and the AdminJS Express simple example you can try this:

const express = require('express');

Promise.all([
    import('adminjs'),
    import('@adminjs/express'),
]).then(([{default: AdminJS}, {default: AdminJSExpress}]) => {
    const PORT = 3000
    const app = express()

    const admin = new AdminJS({})

    const adminRouter = AdminJSExpress.buildRouter(admin)
    app.use(admin.options.rootPath, adminRouter)

    app.listen(PORT, () => {
        console.log(`AdminJS started on http://localhost:${PORT}${admin.options.rootPath}`)
    })
});
