level-list

level-list

Map lists of data stored in a LevelDB to DOM elements.

Example

var List = require('level-list');
var MemDB = require('memdb');

// a levelup style database
var db = MemDB();

// create a list with your db and a function that generates dom elements
var list = List(db, function (row) {
  var el = document.createElement('p');
  el.appendChild(document.createTextNode(row.value));
  return el;
});

// insert the list into the dom
document.body.appendChild(list.el);

// insert some data into the db
(function insert () {
  db.put(Date.now(), (new Date).toString());
  setTimeout(insert, 1000);
})();

API

List(db, fn)

fn is called with row, which has key, value and emits remove events, so you can clean up if necessary.

List#limit(count)

Limit the display to count entries.

List#sort(fn)

Sort the list by the given comparator function, that gets both rows as arguments.

TODO

• sorting with limit
• more convenient sorting abstraction
• pass fn to method instead of constructor?
• infinite scrolling and/or load more
• testling tests
