Here is a list of functions that should be moved and working without bugs.
From https://github.com/GroceriStar/groceristar-fetch/blob/master/src/projects/GS-Loopback/loopback.js need move to https://github.com/GroceriStar/sd/blob/master/generator/projects/GS-Loopback/loopback.js this list of functions:

- [ ] getUserObject

**Note**
---
Some methods for generating Id for each object in array using function __generateId().
For example in `getFavoritesKey()` https://github.com/GroceriStar/groceristar-fetch/blob/master/src/projects/GraphQL/graphQL.js#L38 using `__generateId()`
https://github.com/GroceriStar/groceristar-fetch/blob/master/src/projects/GraphQL/graphQL.js#L43
In this repository (SD) you can find `__generateId()` and `__generateDate` in https://github.com/GroceriStar/sd/blob/master/src/utils.js.
When you will be importing `__generateId()` and `__generateDate()` use this

```
const { __generateDate, __generateId } = require('../../../src/utils')
```

Uncomment test for the function that you have moved in graphQL.test.js https://github.com/GroceriStar/sd/tree/master/generator/projects/GraphQL/test
