@Raruto need to check if need to add 'util-deprecate' here:

g3w-client/gulpfile.js

Line 58 in b7e2545

const dependencies = Object.keys(packageJSON.dependencies).filter(dep => dep !== 'vue');

[Raruto]

@volterra79 I think it shouldn't be necessary to edit the gulpfile:

TEST PERFORMED: util-deprecate is included generated bundle

it should print [G3W] g3sdk.info is deprecated within browser console

/* src/globals.js */

window.g3wsdk = require('app/api');

const deprecate = require('util-deprecate');

window.g3wsdk.info = deprecate(window.g3wsdk.info, '[G3W] g3sdk.info is deprecated');
