React-Native issue

[raynoppe]

Hi

I get the following error when I run the following:

import PouchDB from 'pouchdb-react-native';
PouchDB.plugin(require('pouchdb-find'));
PouchDB.plugin(require('pouchdb-quick-search')); // <= causes the error

Error:
Unable to resolve module crypto from /Users/raynoppe/Sites/reactNative/mapped/node_modules/pouchdb-quick-search/lib/pouch-utils.js: Module does not exist in the module map or in these directories:
/Users/raynoppe/Sites/reactNative/mapped/node_modules/pouchdb-quick-search/node_modules
, /Users/raynoppe/Sites/reactNative/mapped/node_modules

I installed crypto via nom and still the same error.

Thank you

Got it to work. Had to do the following:
Install https://github.com/mvayngrib/react-native-crypto follow the workflow.

In the lib/pouch-utils.js change line 79 from 'var crypto = require('crypto');' to 'var crypto = require('react-native-crypto');' and it works 👍

I had the same problem in Angular 7. This helped: Reference Patch

[gstvg]

Faced the same problem. I'm using my fork gstvg/pouchdb-quick-search. To use this, just put on package.json:
"pouchdb-quick-search": "https://github.com/gstvg/pouchdb-quick-search/tarball/master",

Solution of @gstvg works fine on React Native.
Thank you very much.

The crypto module is only needed to build an md5 hash.

https://github.com/pouchdb-community/pouchdb-quick-search/blob/master/lib/pouch-utils.js#L79

Seeing as react-native-crypto is not a perfect drop-in replacement for crypto, a more robust solution would be to

1. not require crypto if it's not needed
2. switch to a better env detection than checking for process.browser

My quick fix was replacing the whole code block with a call to the md5 library
