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.

## 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. (Optional) Install the correct node version using [nvm](https://github.com/nvm-sh/nvm):



```

nvm install

```



3. Install development dependencies (Note: Check the `package.json` engine for our tested and supported node versions): 



```

npm install

```



4. Run a local development server:



```

npm start

```



> [!IMPORTANT]

> Open MCT is now running, and can be accessed by pointing a web browser at [http://localhost:8080/](http://localhost:8080/)



Open MCT is built using [`npm`](http://npmjs.com/) and [`webpack`](https://webpack.js.org/).



## Documentation



Documentation is available on the [Open MCT website](https://nasa.github.io/openmct/documentation/).

## Developing Applications With Open MCT



For more on developing with Open MCT, see our documentation for a guide on [Developing Applications with Open MCT](./API.md#starting-an-open-mct-application).



## Compatibility



This is a fast moving project and we do our best to test and support the widest possible range of browsers, operating systems, and nodejs APIs. We have a published list of support available in our package.json's `browserslist` key.



The project uses `nvm` to ensure the node and npm version used, is coherent in all projects. Install nvm (non-windows), [here](https://github.com/nvm-sh/nvm) or the windows equivalent [here](https://github.com/coreybutler/nvm-windows)



If you encounter an issue with a particular browser, OS, or nodejs API, please file a [GitHub issue](https://github.com/nasa/openmct/issues/new/choose)



## Plugins



Open MCT can be extended via plugins that make calls to the Open MCT API. A plugin is a group 

of software components (including source code and resources such as images and HTML templates)

that is intended to be added or removed as a single unit.



As well as providing an extension mechanism, most of the core Open MCT codebase is also 

written as plugins.



For information on writing plugins, please see [our API documentation](./API.md#plugins).



## Tests



Our automated test coverage comes in the form of unit, e2e, visual, performance, and security tests. 



### Unit Tests

Unit Tests are written for [Jasmine](https://jasmine.github.io/api/edge/global)

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`.



### e2e, Visual, and Performance tests

The e2e, Visual, and Performance tests are written for playwright and run by playwright's new test runner [@playwright/test](https://playwright.dev/). 



To run the e2e tests which are part of every commit:



`npm run test:e2e:stable`



To run the visual test suite:



`npm run test:e2e:visual`



To run the performance tests:



`npm run test:perf`



The test suite is configured to all tests located in `e2e/tests/` ending in `*.e2e.spec.js`. For more about the e2e test suite, please see the [README](./e2e/README.md)



### Security Tests

Each commit is analyzed for known security vulnerabilities using [CodeQL](https://codeql.github.com/docs/codeql-language-guides/codeql-library-for-javascript/). The list of CWE coverage items is available in the [CodeQL docs](https://codeql.github.com/codeql-query-help/javascript-cwe/). The CodeQL workflow is specified in the [CodeQL analysis file](./.github/workflows/codeql-analysis.yml) and the custom [CodeQL config](./.github/codeql/codeql-config.yml).



### Test Reporting and Code Coverage



Each test suite generates a report in CircleCI. For a complete overview of testing functionality, please see our [Circle CI Test Insights Dashboard](https://app.circleci.com/insights/github/nasa/openmct/workflows/the-nightly/overview?branch=master&reporting-window=last-30-days)



Our code coverage is generated during the runtime of our unit, e2e, and visual tests. The combination of those reports is published to [codecov.io](https://app.codecov.io/gh/nasa/openmct/)



For more on the specifics of our code coverage setup, [see](TESTING.md#code-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.



* _plugin_: A plugin is a removable, reusable grouping of software elements.

  The application is composed of plugins.

* _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.

* _identifier_: A tuple consisting of a namespace and a key, which together uniquely

  identifies a domain object.

* _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.)

* _namespace_: A name used to identify a persistence store. A running open MCT 

application could potentially use multiple persistence stores, with the 



## Open MCT v2.0.0

Support for our legacy bundle-based API, and the libraries that it was built on (like Angular 1.x), have now been removed entirely from this repository.



For now if you have an Open MCT application that makes use of the legacy API, [a plugin](https://github.com/nasa/openmct-legacy-plugin) is provided that bootstraps the legacy bundling mechanism and API. This plugin will not be maintained over the long term however, and the legacy support plugin will not be tested for compatibility with future versions of Open MCT. It is provided for convenience only.



### How do I know if I am using legacy API?

You might still be using legacy API if your source code



* Contains files named bundle.js, or bundle.json,

* Makes calls to `openmct.$injector()`, or `openmct.$angular`,

* Makes calls to `openmct.legacyRegistry`, `openmct.legacyExtension`, or `openmct.legacyBundle`.



### What should I do if I am using legacy API?

Please refer to [the modern Open MCT API](https://nasa.github.io/openmct/documentation/). Post any questions to the [Discussions section](https://github.com/nasa/openmct/discussions) of the Open MCT GitHub repository.
