You can query CouchDB using JavaScript by writing required map function. Go to http://127.0.0.1:5984/_utils/YOUR_DATABASE_NAME.html?restaurant/_temp_view and write your function:
function(doc) {
emit(doc.name, doc.content);
}We can create custom views based on our map() function and save them for later use
View can be further sorted using HTTP GET ?key="" param, for example?key="Delivery"
CouchDB can also serve binary files (images for example). You can add files to your documents using **attachments **feature.
Q: Where to find actual files?
A: They are stored in var\lib\couchdb in Windows:
C:\Program Files (x86)\Apache Software Foundation\CouchDB\var\lib\couchdb # windows
Q: How to secure your databases?
A: You should create an admin user and change configuration option require valid user to true. After that you have to supply user an password for query data: http://admin:[email protected]:5984/restaurant/_all_docs
