Enable Cors on Pouchdb and Fauxton

[bishal1994]

Hello , I am creating a Cordova-Android app that runs express-pouch server in its backend. After going through all the issues and discussions, I tried to implement the

        overrideMode: {
         include: ['routes/fauxton']
         }

I got the fauxton but the configuration tab is blank , for which I am unable to enable the CORS. Then I tried to provide the config.json file enabling the CORS but still CORS was not activated. I tried to download the pouchdb-fauxton and did the npm link and also linked to the express-pouch but no luck.

config.json

 {
    "httpd": {
    "enable_cors": true
 },
 "cors": {
    "credentials": true,
    "methods": "GET, PUT, POST, HEAD, DELETE, OPTIONS",
    "origins": "*",
   "headers": "accept, authorization, content-type, origin, referer, x-csrf-token"
  },
"httpd":{"Bind_address":"0.0.0.0"}
 }

Tried to use CORS package and tried to activate in express

main.js

var argv = require('minimist')(process.argv.slice(2));
var logLocation=argv.pouchlog; 
var express = require('express');
var app = express(); 
var PouchDB = require('pouchdb');
var cors = require('cors');

   let InMemPouchDB = PouchDB.defaults({db: require("memdown"), migrate: true})
   let pouchHandle = require('express-pouchdb')(InMemPouchDB, 
   {mode:'minimumForPouchDB',configPath:'./config.json',logPath:logLocation });
   app.use("/",cors(corsConfig),pouchdbHandle);
   app.listen(3000);
   let db = new InMemPouchDB('test');
   db.changes({live:true}).on('change',console.log);

Please can anyone help me with activating the CORS on the express-pouch server ? Any help will be greatly appreciated.

Even though I enable the cors via couchConfig.set but still it doesn't sync with the couches on another domain. It only works for local network syncing . Please guys need some help in this context ,I am new to all these.

Were you able to figure this out? Having issues with getting the config.json issues figured out

@BillMeyerRSA if you are talking about cors then I wasn't able to make it work with the cors library that I used above. So I had to make my own and it worked fine. But as of config.json I guess not switched to other libs due to lack of support here

To get CORS working with the express app, I had to use pouchdb-server's cors library:

const PouchDB = require('pouchdb');
const express = require('express');
const expressPouch = require('express-pouchdb')
const cors = require('pouchdb-server/lib/cors')

const app = express();

const pouchDBApp = expressPouch(PouchDB, {
    mode: 'fullCouchDB',
    configPath: './config.json'  <-- defaults to this
})

app.use(cors(pouchDBApp.couchConfig)) // <-- needed
app.use(pouchDBApp);
app.listen(8000, () => {
    console.log('listening on ==> http://localhost:8000')
});

With the following set in config.json:

{
  "cors": {
    "methods": "GET, PUT, POST, HEAD, DELETE",
    "origins": "*",
    "headers": "accept, authorization, content-type, origin, referer"
  },
  "httpd": {
    "enable_cors": true
  }
}
