MyDB client component


MyDB client component.

$ npm install mydb-client

Compile with browserify.

var mydb = require('mydb')('');

Connects to the mydb server listening on url. If a parameter is not supplied it will connect to window.location Alternatively, an client options object can be supplied.

Creates a Document by subscribing to the supplied url. Supplying a url is optional, if a vanilla document is desired. See Document#load below.

Each document represents a subscription to a given resource URL.

Returns the associated manager.

Returns the sebscription id.

  • unloaded: no subscription (default when no url was provided)
  • loading: loading a resource
  • loaded: resource is loaded
  • unloading: subscription is being destroyed

Returns the url this document is loaded from / loading.

Loads a document from the given URL. If fn is supplied, it's passed to ready.

Reloads from the URL that was previously given to Document#load. Useful if a given endpoint can return different documents depending on the circumstances. Example: a /me route that returns the currently signed-in user.

Calls the supplied fn when the resource is loaded. If the resource is already loaded, the function is fired on the next tick.

Returns the value of the given key, which can use dot notation. It throws if the document is not loaded. If fn is supplied, ready is called first, and the value is passed to the callback.

Subscribes to changes for the given key.

  • If no operator is supplied, fn gets called upon any operation.
  • Operations that don't change the document are ignored by mongo-query.
  • If an operation is supplied as the second parameter, the first parameter of the event callback will be the value property of the log object. For example, if the operation is a $push, the value that's pushed is the first parameter.
  • Otherwise, the first parameter is always the new value of the given key (after). For example, if the operation is acting on an array, like pushing, pulling or popping, you will still get the reference to the entire array.
  • The second parameter of the event callback is always the log object returned by mongo-query.

Calls ready, then calls fn with the initial value of the given key, and subscribes to subsequent change events for key.

Calls ready, then calls fn for each value of the array found under key.

Destroys this subscription. fn gets called when the unsubscription for the current id is confirmed.
