Problem: Slack only allows teams to invite people via manually sent emails (assuming you don't all have the same email domain). If your team is large and disparate, there's no easy way to point everyone to a URL and have them signup. Until Slack provides a way for users to request team entry, there needs to be a way to tell slack admins that someone is ringing the doorbell.
This web app will allow someone to fill out a form which posts their signup request to a Slack channel.
demo -> http://slacksignup.meteor.com/ (errors on posting to empty Slack team, but still works more or less)
Inspired by https://www.npmjs.org/package/hubot-slack-invite-request
Follow the Meteor Tutorial to install meteor: https://www.meteor.com/install
This simple app uses Meteor's built-in account system to log someone in and let the submit a form requesting Slack team access. Note: The demo doesn't actually post anywhere.
- Makes Webhook calls from server
- Makes DOM style updates the Meteor way rather then jQuery
- Use of fantastic
accounts
packages for OAuth - Form submit to server method
- Encrypts OAuth keys, and auto-deletes accounts after 1 day
- Only 70 lines of js and 81 html
All needed settings should be set in a settings.json
file (or similar). example-settings.json
is included. For security, .gitignore
will ignore files named settings.json
and config.json
so you don't put your secrets in github public.
Use meteor add accounts-*
and meteor remove accounts-*
to control which signin options are available. More info: http://docs.meteor.com/#/basic/accounts
Note that when adding 3rd party OAuth options, you need to configure each one. Easiest way is to configure via web gui, which will store the OAuth config/secrets in MongoDB under db.meteor_accounts_loginServiceConfiguration
. Optionally, you can configure in-app using the Meteor package service-configuration
, more info http://docs.meteor.com/#/full/meteor_loginwithexternalservice.
If storing OAuth keys, you might want to encrypt them. There are settings to enable this, and info of how to setup is at server/server.js
. Disabled by default.
Extra layer of security, since this is something people only do once, is to have MongoDB TTL delete user accounts from the database after 1 day. You'll need to give a command to Mongo directly, more info in server/server.js
.
To signin without bothering to configure any of the OAuth's for 3rd party services you can always use username/password by adding meteor add accounts-password
.
By default, slack-signup will send a request to a channel called 'organizers', overriding whatever you've configured in the Slack webhook. If it doesn't exist in your Slack account, you'll get an error like 'Warning! Error: failed [500] Invalid channel specified'. If you'd like to change the channel override, you'll need to open up 'server/methods.js' and change it there.
- Create your
settings.json

. - Minimum requirement In your settings file is your Slack Incoming Webhook URL.
meteor run --settings yoursettingsfile.json
.
- Add/remove the accounts packages you want to use (find in
.meteor/packages
). - Get OAuth keys for services you want and add them to
settings.json
. - Change out your
public/favicon.ico
if you want. - Deploy to free meteor hosting
