@bang88 Could you fill in the steps to reproduce this issue?

[bang88]

I will test it later.

[bang88]

@ashwinphatak The problem are still there.

Just run jest test your js files if one of them imports realm. I have update realm to 2.0.1.

[ashwinphatak]

@bang88 I can't reproduce the issue in a test project. Can you check if this code works for you?

Realm import in test file:
https://github.com/ashwinphatak/RealmIssue1422/blob/master/__tests__/App.js#L5

Test run:

[bang88]

@ashwinphatak I tested like you said. here is my tests file

import Realm from 'realm';

just one line code

errors:

$ yarn test -o
yarn run v1.2.1
$ jest -o

Unfortunately, I can't reproduce it when running yarn test either. Could you upload a minimal RN project which reproduces the issue?

[bang88]

I can't reproduce it using your repo. Maybe something wrong with my code. I will check it later. 😢

[EJohnF]

@bang88 by the end, have you figured it out? I have the same problem

[bang88]

@EJohnF Not yet. 😢

[EJohnF]

@bang88 try to modify your package.json:
"jest": {
"preset": "react-native",
"transformIgnorePatterns": [
"node_modules/(realm)/"
]
}

it helps me

[brascene]

@EJohnF wow and thank you very much, ignoring "node_modules/(realm)/"helped me resolve _return outside of function_ error!

[donni106]

Sadly I came across the same problem. Adding realm to the transformIgnorePatterns did not worked for me.

FAIL  tests/App.test.js
  ● Test suite failed to run

    /Users/u/Development/project/app/node_modules/realm/lib/submit-analytics.js: 'return' outside of function (30:4)
        28 | if ('REALM_DISABLE_ANALYTICS' in process.env) {
        29 |     module.exports = function(){};
      > 30 |     return;
           |     ^
        31 | }
        32 | 
        33 | const os = require('os');

Is there another solution?
What could I have forgotten?

[dkpalmer]

I also just ran into the _'return' outside of function_ error, ironically _after_ I added realm to transformIgnorePatterns while trying to resolve another error (SyntaxError: Unexpected token import).

 FAIL  src/store/data/queries.spec.js
  ● Test suite failed to run

    /Users/me/project/node_modules/realm/lib/submit-analytics.js: 'return' outside of function (30:4)
        28 | if ('REALM_DISABLE_ANALYTICS' in process.env) {
        29 |     module.exports = function(){};
      > 30 |     return;
           |     ^
        31 | }
        32 |
        33 | const os = require('os');

And from my jest config:

    "transformIgnorePatterns": [
      "node_modules/(?!(react-native|redux-persist|glamorous-native|realm)/)"
    ],

Did you resolve this @donni106?

[dkpalmer]

I was able to resolve the issue with the following in .babelrc:

"parserOpts": {
  "allowReturnOutsideFunction": true,
},
