Chat Bridge by Google Cloud Functions
Framework for Google Cloud Functions to bridge communications in chat services, such as
- LINE -> Slack
- Slack -> LINE
Example of your index.js
const { Bridge } = require("cf-chat-bridge");
// Your secret variables, see following for more details.
const secrets = require("./your/secrets");
// Your rules to bridge messages, see following for more details.
const rules = require("./your/rules");
// Initialize your bridge.
const bridge = new Bridge({rules, secrets});
// Export your endpoint as a member of module,
// so that Google CloudFunctions can listen /foobar as an endpoint.
exports.foobar = bridge.endpoint();
// Then you can use following endpoints for Slack & LINE webhooks:
// - Slack: /foobar?source=SLACK
// - LINE: /foobar?source=LINE
Example rules
module.exports = [
/**
* ONE-WAY bridge: LINE group → SLACK channel(s)
*/
{
// From any groups of LINE in which the bot is a member
source: {
service: "LINE",
group: /.*/
},
// To "random" channel of Slack in which the bot is a member
destination: {
service: "Slack",
channels: ["random"]
}
},
/**
* ONE-WAY bridge: Slack channel → LINE group(s)
*/
{
source: {
service: "Slack",
channel: "dev-test"
},
destination: {
service: "LINE",
to: ["C3a08fbcbd1c7c3dc4c68d42fb46bd112"],
