[Farah Javed]

this screenshot is taken from jsreport playground. Here is the actual screenshot

hmm if you installed ejs with npm install jsreport-ejs the extension should be loaded, what is the content of your package.json? and what are the full logs that you get when starting jsreport?

[Farah Javed]

Content of package.json in jsreportapp folder. I can see the node_module jsreport-ejs in jsreportapp\node_module folder. I don't know which step am i missing to make it work. Our most of reporting templates are written in ejs, so its super important for us to install this modules for jsreport v2

Could you please share also the server.js file content?

[Farah Javed]

here is file content of server.js

const jsreport = require('jsreport')()

if (process.env.JSREPORT_CLI) {
  // export jsreport instance to make it possible to use jsreport-cli
  module.exports = jsreport
} else {
  jsreport.init().then(() => {
    // running
  }).catch((e) => {
    // error during startup
    console.error(e.stack)
    process.exit(1)
  })
}

[jan_blaha]

hm, that looks normal, that is mystery...

I believe the key will be in this lines

resolving jsreport location..
using jsreport instance passed from options

That is something that should not be there. @bjrmatos will know better what that means.

Maybe as a workaround you can use just this to boot up

node server.js

[Farah Javed]

node server.js does not work

[jan_blaha]

I guess you have very old npm right?
Can you type this?

npm --version

I would guess you have something like v2 and you should have something like v6

Can you upgrade it and reinstall jsreport?

[Farah Javed]

npm and node versions are up to date

C:\>npm --version
6.4.1

C:\>node --version
v10.5.0

[Farah Javed]

do i need to configure anything in jsreport.config.json file so that it can detect ejs engine?

[jan_blaha]

No you don't need any configuration. I tried the latest npm and have no issues on windows.
I would recommend to uninstall node, remove jsreportapp. Reboot and start from scratch.

The error you posted Error: Cannot find module 'node.extend' should not happen at all if you install jsreport with your npm.
Isn't there any error when calling jsreport init ?

[Farah Javed]

turned off npm legacy-bundling and it worked. Thanks for the help
