THE MAGIC IS ABOUT TO HAPPEN ...

import { authenticateUser, findUser } from "../../server/boot/ldap.conf";

The reason is that I`m using import statemtent (es6 with Babel) in one of the Model.js files ....

'use strict';
import { authenticateUser, findUser } from "../../server/boot/ldap.conf";

Anyone has a clue how to fix it and keep this es6 feature ?

Greetings,

Same problem with babel... have you found a workaround?

[jonathan-casarrubias]

Hey guys, thanks for reaching out... Well that is an extremely weird issue,

I don't even see any file provided by the SDK builder being executed in that stack, I'm not entirely sure what is related since is not directly related to the SDK.

But, indirectly the SDK does run your app, to get all the model instances and rules you define, and then iterate those in order to build an SDK... At this point I don't even see the boot gets to finish.

So my assumption is: You need to either transpile your models, and then point that transpiled source within the SDK, instead of the ES6 one you are using OR execute the SDK with babel as well instead of pure node command.

I hope this information guides you to find the fix.

Cheers Jon

Hi @jonathan-casarrubias, thanks for your comments. In order to use babel, I've made an app.js file that imports babel and requires server/server.js. In fact, the error that i'm gettin is this one when I run lb-sdk with app.js file as first argument:

/mnt/sda6/fleita/Desarrollo/Humber/api/node_modules/@mean-expert/loopback-sdk-builder/bin/lb-sdk:98
  apiUrl: argv['url'] || app.get('restApiRoot') || '/api',
                             ^

TypeError: app.get is not a function

I think I should fork this repo, version 2.2.1, so that i can get the loopback app reference correctly.

[fleita9]

var app = require(appFile).default; made the trick.

Gracias!

@fleita9 so cool you were able to fix it. I'll keep this issue open for some time, so anyone having this issue can have the reference.

Cheers Jon
