node-slack
A node module for sending and receiving messages with Slack via webhooks that works with browserify.
Slack is a messaging platform that is easy to integrate with. This module should be useful for creating various integrations with Slack, such as chat bots!
Install Slack
node-slack is available via npm:
npm i -S node-slack
Get your custom hook url from Slack by setting up an integration.
var Slack = require('browser-node-slack');
var slack = new Slack('https://hooks.slack.com/services/EXAMPLEHOOK');
If your system requires that requests be made through an HTTP or HTTPS proxy, you can either set an environment variables https_proxy and http_proxy, or pass in the optional second option:
var slack = new Slack(hook_url, {proxy: http_proxy});
To send a message, call slack.send:
slack.send({
text: 'Howdy!',
channel: '#foo',
username: 'Bot'
});
You can also specify an emoji icon, a url to a custom icon, attachments, and any of the other options listed here.
slack.send({
text: 'Howdy!',
channel: '#foo',
username: 'Bot',
icon_emoji: 'taco',
attachments: attachment_array,
unfurl_links: true,
link_names: 1
});
To respond to an outgoing webhook from slack, pass the information from the webhook into slack.respond, along with a callback function responsible for returnign a response.
From inside an Express.js route, this is as easy as passing in req.body:
app.post('/yesman',function(req,res) {
var reply = slack.respond(req.body,function(hook) {
return {
text: 'Good point, ' + hook.user_name,
username: 'Bot'
};
});
res.json(reply);
});
