add cors to couchdb

Summary

CouchDB doesn't come with CORS enabled by default. This is a problem for libraries like PouchDB, which depend on being able to access CouchDB no matter what URL it's being served from.

This script fixes that.

Usage

npm install -g add-cors-to-couchdb
add-cors-to-couchdb

or if it is a remote database:

add-cors-to-couchdb http://me.iriscouch.com -u myusername -p mypassword
Ubuntu - special instructions

On Ubuntu the default Node.js library is called nodejs instead of node due to a naming conflict. To run on Ubuntu, you'll need to do:

sudo apt-get install nodejs-legacy

What it does

This script will simply add some generic CORS configuration to your CouchDB. You could also do it yourself trivially using curl:

HOST=http://adminname:password@localhost:5984 # or whatever you got

curl -X POST $HOST/_config/httpd/enable_cors -d '"true"'
curl -X PUT $HOST/_config/cors/origins -d '"*"'
curl -X PUT $HOST/_config/cors/credentials -d '"true"'
curl -X PUT $HOST/_config/cors/methods -d '"GET, PUT, POST, HEAD, DELETE"'
curl -X PUT $HOST/_config/cors/headers -d '"accept, authorization, content-type, origin, referer"'

You can always change the configuration later by simply going to http://localhost:5984/_utils/config.html and updating the values. However, these default options are good for getting up and running.
