Slack Developer Kit for Node.js slack typescript websocket websockets websocket-client slackapi socket-mode TypeScript MIT 616 2,887 65 (10 issues need help) 11 Updated Apr 19, 2021. A Slack account and active Slack instance to deploy your bot on Installing Node and NPM To install the necessary software for this project, we will first need Node.js, a JavaScript runtime. Visit the official Node.js website to get the installer.

The @slack/webhook package contains a helper for making requests to Slack’s IncomingWebhooks. Use it in your app to send a notification to a channel.

Installation

Initialize the webhook

The package exports a IncomingWebhook class. You’ll need to initialize it with the URL you received from Slack.

The URL can come from installation in your development workspace, which is shown right in the app configuration pages.Or, the URL could be in the response from oauth.v2.access when the app isdistributed and installed into another workspace.

The webhook can be initialized with default arguments that are reused each time a notification is sent. Use the secondparameter to the constructor to set the default arguments.

Send a notification

Something interesting just happened in your app, so its time to send the notification! Just call the.send(options) method on the webhook. The options parameter is an object that should describe the contents ofthe message. The method returns a Promise that resolves once the notification is sent.

Proxy requests with a custom agent

The webhook allows you to customize the HTTPAgent used to create the connection to Slack.Using this option is the best way to make all requests from your app through a proxy, which is a common requirement inmany corporate settings.

Slack Node Js

In order to create an Agent from some proxy information (such as a host, port, username, and password), you can useone of many npm packages. We recommend https-proxy-agent. Startby installing this package and saving it to your package.json.

Slack Sdk

Import the HttpsProxyAgent class, and create an instance that can be used as the agent option of theIncomingWebhook.
