Sample using VSCode extensions that communicate via events

This repo contains the source for 2 VS Code extensions that demonstrate the ability to distinct extensions communicate with each other. In this instance, this is via an event. The extension in the producer folder, vscode-event-emitter, will setup an event and expose a function that will allow others to subscribe to this event. In this example the payload of the event is a simple string value. The extension in the consumer folder, vscode-event-consumer, will subscribe to the event from the producer. Upon receiving the event, it will raise a notification with the event payload (string value).

Build

cd producer
npm install
npm run package

cd ../consumer
npm install
npm run package

This will compile and package the extensions into vsix format, which can be sideloaded into VS Code.

Install

Run the command Extensions: Install from VSIX..., choose the vsix files generated via the build instructions above.

Run

To demonstrate the event subscription, trigger and result:

1. First setup the consumer to listen to the event that the producer will emit. This can be done by calling the following command Sample Event Consumer

2. Next emit the event from the producer. This can be done by calling the following command Sample Event Producer

3. You should then be prompted for a text (string) value to include with the event. After submitting this, a notification prompt will be shown from the consumer with this event data.
