* Move to webpack build * Use webpack for building openmct. Move SCSS to one folder and load all core css up front. Remove bower, begin removing gulp in favor of npm run. * Uses eslint instead of jshint and jscs. Merge style checking rules into .eshintrc.js, carrying over core parts of crockford style and our adaptations. Current code base fails to pass the linter, want to separate linter changes from fixes to linting rules. * Support for Vue SFC with example * Remove outdated examples * Use HTML loader for html (supports relative imports of resources e.g. images) and raw-loader for when javascript must be loaded as text.

# Open MCT [](http://www.apache.org/licenses/LICENSE-2.0)
|
|
|
|
Open MCT (Open Mission Control Technologies) is a next-generation mission control framework for visualization of data on desktop and mobile devices. It is developed at NASA's Ames Research Center, and is being used by NASA for data analysis of spacecraft missions, as well as planning and operation of experimental rover systems. As a generalizable and open source framework, Open MCT could be used as the basis for building applications for planning, operation, and analysis of any systems producing telemetry data.

## New API
|
|
|
|
A simpler, [easier-to-use API](https://nasa.github.io/openmct/docs/api/)
|
|
has been added to Open MCT. Changes in this
|
|
API include a move away from a declarative system of JSON configuration files
|
|
towards an imperative system based on function calls. Developers will be able
|
|
to extend and build on Open MCT by making direct function calls to a public
|
|
API. Open MCT is also being refactored to minimize the dependencies that using
|
|
Open MCT imposes on developers, such as the current requirement to use
|
|
AngularJS.
|
|
|
|
This new API has not yet been heavily used and is likely to contain defects.
|
|
You can help by trying it out, and reporting any issues you encounter
|
|
using our GitHub issue tracker. Such issues may include bugs, suggestions,
|
|
missing documentation, or even just requests for help if you're having
|
|
trouble.
|
|
|
|
We want Open MCT to be as easy to use, install, run, and develop for as
|
|
possible, and your feedback will help us get there!
|
|
|
|
## Building and Running Open MCT Locally
|
|
|
|
Building and running Open MCT in your local dev environment is very easy. Be sure you have [Git](https://git-scm.com/downloads) and [Node.js](https://nodejs.org/) installed, then follow the directions below. Need additional information? Check out the [Getting Started](https://nasa.github.io/openmct/getting-started/) page on our website.
|
|
(These instructions assume you are installing as a non-root user; developers have [reported issues](https://github.com/nasa/openmct/issues/1151) running these steps with root privileges.)
|
|
|
|
1. Clone the source code
|
|
|
|
`git clone https://github.com/nasa/openmct.git`
|
|
|
|
2. Install development dependencies
|
|
|
|
`npm install`
|
|
|
|
3. Run a local development server
|
|
|
|
`npm start`
|
|
|
|
Open MCT is now running, and can be accessed by pointing a web browser at [http://localhost:8080/](http://localhost:8080/)
|
|
|
|
## Documentation
|
|
|
|
Documentation is available on the [Open MCT website](https://nasa.github.io/openmct/documentation/). The documentation can also be built locally.
|
|
|
|
### Examples
|
|
|
|
The clearest examples for developing Open MCT plugins are in the
|
|
[tutorials](https://github.com/nasa/openmct-tutorial) provided in
|
|
our documentation.
|
|
|
|
For a practical example of a telemetry adapter, see David Hudson's
|
|
[Kerbal Space Program plugin](https://github.com/hudsonfoo/kerbal-openmct),
|
|
which allows [Kerbal Space Program](https://kerbalspaceprogram.com) players
|
|
to build and use displays for their own missions in Open MCT.
|
|
|
|
Additional examples are available in the `examples` hierarchy of this
|
|
repository; however, be aware that these examples are
|
|
[not fully-documented](https://github.com/nasa/openmct/issues/846), so
|
|
the tutorials will likely serve as a better starting point.
|
|
|
|
### Building the Open MCT Documentation Locally
|
|
Open MCT's documentation is generated by an
|
|
[npm](https://www.npmjs.com/)-based build. It has additional dependencies that
|
|
may not be available on every platform and thus is not covered in the standard
|
|
npm install. Ensure your system has [libcairo](http://cairographics.org/)
|
|
installed and then run the following commands:
|
|
|
|
* `npm install`
|
|
* `npm install canvas nomnoml`
|
|
* `npm run docs`
|
|
|
|
Documentation will be generated in `target/docs`.
|
|
|
|
## Deploying Open MCT
|
|
|
|
Open MCT is built using [`npm`](http://npmjs.com/)
|
|
|
|
To build Open MCT for deployment:
|
|
|
|
`npm run prepare`
|
|
|
|
This will compile and minify JavaScript sources, as well as copy over assets.
|
|
The contents of the `dist` folder will contain a runnable Open MCT
|
|
instance (e.g. by starting an HTTP server in that directory), including:
|
|
|
|
* `openmct.js` - Open MCT source code.
|
|
* `openmct.css` - Basic styles to load to prevent a FOUC.
|
|
* `index.html`, an example to run Open MCT in the basic configuration.
|
|
|
|
## Tests
|
|
|
|
Tests are written for [Jasmine 3](http://jasmine.github.io/)
|
|
and run by [Karma](http://karma-runner.github.io). To run:
|
|
|
|
`npm test`
|
|
|
|
The test suite is configured to load any scripts ending with `Spec.js` found
|
|
in the `src` hierarchy. Full configuration details are found in
|
|
`karma.conf.js`. By convention, unit test scripts should be located
|
|
alongside the units that they test; for example, `src/foo/Bar.js` would be
|
|
tested by `src/foo/BarSpec.js`. (For legacy reasons, some existing tests may
|
|
be located in separate `test` folders near the units they test, but the
|
|
naming convention is otherwise the same.)
|
|
|
|
### Test Reporting
|
|
|
|
When `npm test` is run, test results will be written as HTML to
|
|
`target/tests`. Code coverage information is written to `target/coverage`.
|
|
|
|
# Glossary
|
|
|
|
Certain terms are used throughout Open MCT with consistent meanings
|
|
or conventions. Any deviations from the below are issues and should be
|
|
addressed (either by updating this glossary or changing code to reflect
|
|
correct usage.) Other developer documentation, particularly in-line
|
|
documentation, may presume an understanding of these terms.
|
|
|
|
* _bundle_: A bundle is a removable, reusable grouping of software elements.
|
|
The application is composed of bundles. Plug-ins are bundles. For more
|
|
information, refer to framework documentation (under `platform/framework`.)
|
|
* _capability_: An object which exposes dynamic behavior or non-persistent
|
|
state associated with a domain object.
|
|
* _composition_: In the context of a domain object, this refers to the set of
|
|
other domain objects that compose or are contained by that object. A domain
|
|
object's composition is the set of domain objects that should appear
|
|
immediately beneath it in a tree hierarchy. A domain object's composition is
|
|
described in its model as an array of id's; its composition capability
|
|
provides a means to retrieve the actual domain object instances associated
|
|
with these identifiers asynchronously.
|
|
* _description_: When used as an object property, this refers to the human-readable
|
|
description of a thing; usually a single sentence or short paragraph.
|
|
(Most often used in the context of extensions, domain
|
|
object models, or other similar application-specific objects.)
|
|
* _domain object_: A meaningful object to the user; a distinct thing in
|
|
the work support by Open MCT. Anything that appears in the left-hand
|
|
tree is a domain object.
|
|
* _extension_: An extension is a unit of functionality exposed to the
|
|
platform in a declarative fashion by a bundle. For more
|
|
information, refer to framework documentation (under `platform/framework`.)
|
|
* _id_: A string which uniquely identifies a domain object.
|
|
* _key_: When used as an object property, this refers to the machine-readable
|
|
identifier for a specific thing in a set of things. (Most often used in the
|
|
context of extensions or other similar application-specific object sets.)
|
|
* _model_: The persistent state associated with a domain object. A domain
|
|
object's model is a JavaScript object which can be converted to JSON
|
|
without losing information (that is, it contains no methods.)
|
|
* _name_: When used as an object property, this refers to the human-readable
|
|
name for a thing. (Most often used in the context of extensions, domain
|
|
object models, or other similar application-specific objects.)
|
|
* _navigation_: Refers to the current state of the application with respect
|
|
to the user's expressed interest in a specific domain object; e.g. when
|
|
a user clicks on a domain object in the tree, they are _navigating_ to
|
|
it, and it is thereafter considered the _navigated_ object (until the
|
|
user makes another such choice.)
|
|
* _space_: A name used to identify a persistence store. Interactions with
|
|
persistence will generally involve a `space` parameter in some form, to
|
|
distinguish multiple persistence stores from one another (for cases
|
|
where there are multiple valid persistence locations available.)
