The Node.js Model Server is a façade in front of the Java Model Server that provides an extensible environment for Javascript-based plug-ins. Plug-in contributions are supported for

• custom command providers
• validation providers
• trigger providers that add side-effects to edit requests

Install nvm. Note that 0.36 may not be the latest version, so check that first and substitute the current version in the URL.

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.36.0/install.sh | bash

Install npm and node.

nvm install 12.18.4
nvm use 12.18.4

Install yarn.

npm install -g yarn

Install dependencies and build the Model Server and related packages.

yarn

To run the Model Server example that demonstrates customization plug-ins:

yarn start

The server will listen for incoming requests on port 8082 and will connect to the Upstream Model Server on port 8081 on the local host. This upstream server must be started separately; see the EMF.Cloud Java Model Server project for details.

For verbose logging output, run it so:

yarn start -v

For information about other options:

yarn start --help
