-# Discover Context App Implementation Notes
-
-The implementation of this app is intended to exhibit certain desirable
-properties by adhering to a set of *principles*. This document aims to explain
-those and the *concepts* employed to achieve that.
-
-
-## Principles
-
-**Single Source of Truth**: A good user experience depends on the UI displaying
-consistent information across the whole page. To achieve this, there should
-always be a single source of truth for the application's state. In this
-application this is the `ContextAppController::state` object.
-
-**Unidirectional Data Flow**: While a single state promotes rendering
-consistency, it does little to make the state changes easier to reason about.
-To avoid having state mutations scattered all over the code, this app
-implements a unidirectional data flow architecture. That means that the state
-is treated as immutable throughout the application except for actions, which
-may modify it to cause angular to re-render and watches to trigger.
-
-**Unit-Testability**: Creating unit tests for large parts of the UI code is
-made easy by expressing the as much of the logic as possible as
-side-effect-free functions. The only place where side-effects are allowed are
-actions. Due to the nature of AngularJS a certain amount of impure code must be
-employed in some cases, e.g. when dealing with the isolate scope bindings in
-`ContextAppController`.
-
-**Loose Coupling**: An attempt was made to couple the parts that make up this
-app as loosely as possible. This means using pure functions whenever possible
-and isolating the angular directives diligently. To that end, the app has been
-implemented as the independent `ContextApp` directive in [app.js](app.js). It
-does not access the OpenSearch Dashboards `AppState` directly but communicates only via its
-directive properties. The binding of these attributes to the state and thereby
-to the route is performed by the `CreateAppRouteController`in
-[index.js](index.js). Similarly, the `SizePicker` directive only communicates
-with its parent via the passed properties.
-
-
-## Concepts
-
-To adhere to the principles mentioned above, this app borrows some concepts
-from the redux architecture that forms a ciruclar unidirectional data flow:
-
-```
-
-     |* create initial state
-     v
-  +->+
-  |  v
-  |  |* state
-  |  v
-  |  |* angular templates render state
-  |  v
-  |  |* angular calls actions in response to user action/system events
-  |  v
-  |  |* actions modify state
-  |  v
-  +--+
-
-```
-
-**State**: The state is the single source of truth at
-`ContextAppController::state` and may only be modified by actions.
-
-**Action**: Actions are functions that are called in response to user or system
-actions and may modified the state the are bound to via their closure.
-
-
-## Directory Structure
-
-**index.js**: Defines the route and renders the `<context-app>` directive,
-binding it to the `AppState`.
-
-**app.js**: Defines the `<context-app>` directive, that is at the root of the
-application. Creates the store, reducer and bound actions/selectors.
-
-**query**: Exports the actions, reducers and selectors related to the
-query status and results.
-
-**query_parameters**: Exports the actions, reducers and selectors related to
-the parameters used to construct the query.
-
-**components/action_bar**: Defines the `<context-action-bar>`
-directive including its respective styles.
-
-
-**api/anchor.js**: Exports `fetchAnchor()` that creates and executes the
-query for the anchor document.
-
-**api/context.js**: Exports `fetchPredecessors()`, `fetchSuccessors()`, `fetchSurroundingDocs()` that
-create and execute the queries for the preceeding and succeeding documents.
-
-**api/utils**: Exports various functions used to create and transform
-queries.

-/**
- *  WHAT NEEDS THIS WORKAROUND?
- *  ===========================
- *  Any directive that meets all of the following criteria:
- *   - uses isolate scope bindings
- *   - sets `bindToController: true`
- *   - synchronously accesses the bound values in the controller constructor
- *
- *
- *
- *  HOW DO I GET RID OF IT?
- *  =======================
- *  The quick band-aid solution:
- *    Wrap your constructor logic so it doesn't access bound values
- *    synchronously. This can have subtle bugs which is why I didn't
- *    just wrap all of the offenders in $timeout() and made this
- *    workaround instead.
- *
- *  The more complete solution:
- *    Use the new component lifecycle methods, like `$onInit()`, to access
- *    bindings immediately after the constructor is called, which shouldn't
- *    have any observable effect outside of the constructor.
- *
- *    NOTE: `$onInit()` is not dependency injected, if you need controller specific
- *      dependencies like `$scope` then you're probably using watchers and should
- *      take a look at the new one-way data flow facilities available to
- *      directives/components:
- *
- *      https://docs.angularjs.org/guide/component#component-based-application-architecture
- *
