Open MCT for MCWS

Open Mission Control Technologies for Mission Control Web Services (Open MCT for MCWS) is a next-generation web-based mission control framework for visualization of data on desktop and mobile devices. Open MCT for MCWS is built on the Open MCT Framework, and includes adapter code for using MCWS as a telemetry and persistence provider. Open MCT is developed at NASA Ames Research Center in Silicon Valley, in collaboration with NASA AMMOS and the Jet Propulsion Laboratory, California Institute of Technology (under its contract with NASA, 80NM0018D0004).

Configuration

Various configurations and customizations are available by editing config.js. Descriptions of each configuration reside with the configuration in the file.

AMMOS configurations

1. camUrl: The url to the CAM server, if CAM is to be used for authentication.
2. mcwsUrl: The url to the MCWS server.
3. In the namespaces configuration, url, the path to the MCWS persistence spaces, are required.

Development

1. Install Open MCT for MCWS

In a terminal, run this command to install Open MCT for MCWS and its dependencies. This may take a few minutes.

npm install

If you've installed Open MCT for MCWS locally before, first run this command.

npm run clean

2. Modify config.js

Uncomment the proxyUrl setting in config.js. It is located under Developer Settings near the end of the file.

3. Run Open MCT for MCWS locally

npm start

With that running, browse to http://localhost:8080/ to access Open MCT for MCWS.

4. Rebuilding SASS stylesheets

npm run build:prod

With the stylesheets rebuilt, you can reload your browser (assuming the server is running) to see the rebuilt CSS.

Development MCWS server

To connect Open MCT for MCWS to MCWS, either run a local mock server, run MCWS locally, or connect to a remote instance of MCWS.

Running a mock MCWS server

An example mock mcws server - https://github.com/davetsay/mcws-test-server *requires request access

Running MCWS locally

Refer to MCWS documentation.

Running a development server

Running a development server requires that you are on the JPL network so that you can access a development MCWS server. You'll need to retrieve an authentication cookie and make a small modification to your Open MCT for MCWS configuration; here's how.

1. Get your CAM cookie

To get past CAM, you will need to export an environment variable, COOKIE, that contains your CAM authentication cookie. Instructions for retrieving this cookie are at the bottom of the README. If you've copied your CAM cookie into the clipboard, use this command to set the variable:

export COOKIE=`pbpaste`

Tests

Tests are written for Jasmine 4.4 and run by Karma.

Test files end with Spec.js, and will be automatically executed when running the following command:

npm test

Running the tests creates a code coverage report in target/coverage.

Building for production

npm install
mvn clean install

This will create a deployable artifact, openmct_client.war in the target directory.

Notes

Getting your CAM cookie

Go to the MCWS server location and log in to CAM. Then retrieve the cookie from your browser.

Unsure how to get cookies from the browser? Here's a shortcut: create a bookmarklet with the following code:

javascript:(function () {prompt('Your cookies for ' + location.host, document.cookie);})();

Pressing this bookmarklet will show you your cookies for the current host, which you can then copy into your clipboard to use to set the cookie environment variable. Note that logging out of CAM or getting a new session will require you to get the cookie again.
