From 4da56d251f2ced1d31baa3c52045f2fae74f7952 Mon Sep 17 00:00:00 2001 From: DesiredCO Date: Fri, 29 Nov 2024 11:37:04 -0600 Subject: [PATCH] Add connection Fixes #58 Add connection lost and connection established events to Penpal. * **Parent Connection**: - Add `onConnectionLost` and `onConnection` options to `connectToChild` in `src/parent/connectToChild.ts`. - Call `onConnectionLost` when the connection with the child is lost. - Call `onConnection` when the connection with the child is established or re-established. * **Child Connection**: - Add `onConnectionLost` and `onConnection` options to `connectToParent` in `src/child/connectToParent.ts`. - Call `onConnectionLost` when the connection with the parent is lost. - Call `onConnection` when the connection with the parent is established or re-established. * **Documentation**: - Update `README.md` to include `onConnectionLost` and `onConnection` options for `connectToChild`. - Update `README.md` to include `onConnectionLost` and `onConnection` options for `connectToParent`. * **Tests**: - Add tests in `test/connectionManagement.spec.js` to verify `onConnectionLost` and `onConnection` functionality for `connectToChild`. - Add tests in `test/connectionManagement.spec.js` to verify `onConnectionLost` and `onConnection` functionality for `connectToParent`. --- For more details, open the [Copilot Workspace session](https://copilot-workspace.githubnext.com/Aaronius/penpal/issues/58?shareId=XXXX-XXXX-XXXX-XXXX). --- README.md | 32 +++++++++++++ package-lock.json | 1 + src/child/connectToParent.ts | 17 ++++++- src/parent/connectToChild.ts | 17 ++++++- test/connectionManagement.spec.js | 76 +++++++++++++++++++++++++++++++ 5 files changed, 141 insertions(+), 2 deletions(-) diff --git a/README.md b/README.md index ccbbea4..476a957 100644 --- a/README.md +++ b/README.md @@ -71,6 +71,14 @@ const connection = connectToChild({ return num1 + num2; }, }, + // Callback function to be called when the connection with the child is lost. + onConnectionLost: () => { + console.log('Connection with child lost'); + }, + // Callback function to be called when the connection with the child is established or re-established. + onConnection: () => { + console.log('Connection with child established or re-established'); + }, }); connection.promise.then((child) => { @@ -100,6 +108,14 @@ const connection = connectToParent({ }); }, }, + // Callback function to be called when the connection with the parent is lost. + onConnectionLost: () => { + console.log('Connection with parent lost'); + }, + // Callback function to be called when the connection with the parent is established or re-established. + onConnection: () => { + console.log('Connection with parent established or re-established'); + }, }); connection.promise.then((parent) => { @@ -141,6 +157,14 @@ The amount of time, in milliseconds, Penpal should wait for the child to respond Enables or disables debug logging.
