CouchDB still uses an append-only architecture; document update handlers still create a new doc revision, etc. Still, update handlers are quite convenient and worth learning. Suppose you have a document with an accumulator. You want to accumulate an integer in a … Read more
This simple regular expression works: text.replace(/<[^>]*>/g, ”); It removes all anchors. Entities, like < does not contains <, so there is no issue with this regex.

Here’s the gist straight from the wiki: An anonymous user can only create a new document. An authenticated … Read more
Thank you! This is a great example to show off CouchDB 0.11’s new features! You must use the fetch-related-data feature to reference documents in the view. Optionally, for more convenient JSON, use a _list function to clean up the results. See Couchio’s writeup on “JOIN”s for details. Here is the plan: Firstly, you have a … Read more
For emitting more than one piece of data in a key, you’ll want to read up on Complex Keys. You’ll most likely end up emit()‘ing a key that is an array made up of the category and tag. For example… function(doc) { for(var i = 0; i < doc.tags.length; i++) emit([doc.category, doc.tags[i]], doc); } Now … Read more
The best method seem to be using ES6 and Set. Single line and faster* than above according to fiddle const myList = [1,4,5,1,2,4,5,6,7]; const unique = […new Set(myList)]; console.log(unique); *tested in safari
