Install ejs engine

[Farah Javed]

Can someone please help me installing EJS engine for jsreport v2 server. I followed the instructions on https://jsreport.net/learn/ejs page, but when I start jsreport server and access it using http://localhost:xxxx it doesn't detect ejs engine. I added new module as an extension to configuration file. I want ejs to be available as an option in the dropdown. Our team designs jsreport templates on the server, so its visibility is important. Here is my config file

  
  "httpPort": xxxx,
  "store": {
    "provider": "fs"
  },
  "blobStorage": {
    "provider": "fs"
  },
  "logger": {
    "console": {
      "transport": "console",
      "level": "debug"
    },
    "file": {
      "transport": "file",
      "level": "info",
      "filename": "logs/reporter.log"
    },
    "error": {
      "transport": "file",
      "level": "error",
      "filename": "logs/error.log"
    }
  },
  "allowLocalFilesAccess": true,
  "templatingEngines": {
	"allowedModules": ["lodash","request"],
	"numberOfWorkers" : 2,
    "timeout": 10000
  },
  "chrome": {
    "timeout": 40000
  },
  "extensions": {  
	"ejs": {   
      "enabled": true
    },
    "scripts": {
        "allowedModules": ["nodemailer"],
        "timeout": 60000
    },
    "studio": {
		"enabled": true
	}
  }
}

hi! sorry, in your screenshot i see the ejs option already in the engine dropdown, what am i missing?

[Farah Javed]

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

[bjrmatos]

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

{
  "name": "jsreport-server",
  "main": "server.js",
  "scripts": {
    "start": "node server",
    "jsreport": "jsreport"
  },
  "jsreport": {
    "entryPoint": "server.js"
  },
  "dependencies": {
    "jsreport": "2.2.0",
    "jsreport-ejs": "^2.0.0"
  }
}

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
