node-slack

A node module for sending and receiving messages with Slack via webhooks.

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 install node-slack
`


Get your hook_url from the Slack Incoming Webhooks Integration page.

`
var Slack = require('node-slack');
var slack = new Slack(hook_url,options);
`

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 third 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 returning 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);

});
