This project contains [Angular](https://angular.io/) based Modules, Components, Injectables to build a sensor observation service based client.

## Description

### Tools for Building Web Applications
**Providing Reusable Components for Building (Sensor Web) Client Applications**

52°North created the Helgoland Toolbox to facilitate the reuse of developments for Sensor Web client applications. It provides a range of modules that offer functionalities for building Web applications dealing with dynamic spatio-temporal data. The Helgoland Toolbox modules are used to build the 52°North Helgoland Sensor Web Viewer. Additional applications (e.g. the BelAir app, smle, or the developments resulting from the TaMIS project) are also built upon this library.

**Features:**

The most important functional modules comprise:

Core
- Communication with the APIs (Helgoland API and OGC SensorThings API)
- Important common services (local storage, time)
- Central interfaces and abstract classes

Caching
- Request Caching with Angular Interceptors

d3
- Trajectory Graph component
- Time Series Graph component

Depiction
- Legend entries
- Table view of data

Map
- Controls (Geo-Search, Locate, Zoom, Extent)
- Map Selector component

Selectors
- List Selector for observation data
- Service Selector for data sources.

The work on the Helgoland Toolbox focused on improving Helgoland Toolbox’s support of the OGC SensorThings API standard. A dedicated layer to improve the abstraction of underlying data sources enables the Helgoland Sensor Web Viewer to consume data directly from OGC compliant SensorThings API instances as well as connect to the 52°North Helgoland API.
Research covered experimenting on how to achieve the integration of access-controlled data sources and incorporation of near-real time data streams via MQTT. For this purpose, we developed a dedicated dashboard for visualizing research vessel tracking data based on our toolbox. This development was part of the EMODnet Ingestion 2 project.

**Key Technologies:**

- [JavaScript](https://www.javascript.com/)
- [TypeScript](https://www.typescriptlang.org/)
- [Angular](https://angular.io/)
- [Leaflet](https://leafletjs.com/)
- [d3](https://d3js.org/)

 - Mapping modules
 - Different components for data selection
 
## Quick Start

### Dependencies

#### Node/NPM

Install latest Node and NPM following the [instructions](https://nodejs.org/en/download/). Make sure you have Node version ≥ 10 and NPM ≥ 6. `brew install node` for Mac.

### Installing

- `fork` this repository.
- `clone` your fork to your local environment.
- `npm install` to install required dependencies.

### Build the libraries

- `npm run lib:build` for building the library once

### Other commands

#### Lint the complete code

- `npm start` will start the test application, which provide views for the main modules and components
- the app, and their corrensponding files can be found in the `src` folder

### See Documentation

- a module based documentation can be found here: <https://52north.github.io/helgoland-toolbox/>
- there is also a how to page with different use cases: <https://52north.github.io/helgoland-toolbox/additional-documentation/how-tos.html>

<!-- TODO: check how toos, if their are still valid -->

## Development

- different moduls are in the projects folder
<!-- TODO: short description to every module -->

### use customized toolbox in an other app development

#### build Toolbox

- `npm run lib:build` builds the complete toolbox in the `dist`-folder
- after build `npm run lib:pack` packs every module to a file in the following structure `helgoland-MODULENAME-CURRENT_VERSION.tgz` in the `root`-folder
- every packed module can be used by installing it in app development with it's relative path, for example `npm install ../helgoland-toolbox/helgoland-MODULENAME-CURRENT_VERSION.tgz`

### Other commands

#### Run tests

- all implemented tests for the modules can be run by `npm test`

#### Lint the complete code

- `ng lint` for performing static code analysis.

#### Generate documentation

- `npm run compodoc` for generating documentation locally
- `npm run gh-pages` for generating documentation and uploading it to GitHub Pages

##### Bump library version

- `npm version ***` to increase library version. [More on bumping](https://docs.npmjs.com/cli/version).

<!-- `preversion` script in this case will automatically run project testing and linting in prior in order to check that the library is ready for publishing. -->

<!-- ## Supported series API versions mapping

| helgoland-toolbox version | [series rest API](https://github.com/52North/series-rest-api) version |
| :-----------------------: | :-------------------------------------------------------------------: |
|      v0.0.1-alpha.53      |                                v1.10.2                                | -->

## Troubleshooting while using this library

- add `allowSyntheticDefaultImports: true` to your tsconfig.json to avoid error messages like `... has no default export`
- don't forget to add styles of nested dependencies
