A tiny web application to invite a user into your Slack team.
Inspired by How I hacked Slack into a community platform with Typeform and Socket.io's Slack page.
This project supports Heroku, Azure, Cloud Foundry, and Amazon Web Services (AWS).
You can set variables for your own purpose in config.js
or environment variables.
Fill out config.js

You can set environment variables directly or in .env

with the following key/value pairs.
(.env
files are added to the .gitignore
.)

Sample
COMMUNITY_NAME=socketio
SLACK_URL=socketio.slack.com
SLACK_TOKEN=ffsdf-5411524512154-16875416847864648976-45641654654654654-444334f43b34566f

You can test your token via curl:
curl -X POST 'https://YOUR-SLACK-TEAM.slack.com/api/users.admin.invite' \
--data 'email=EMAIL&token=TOKEN&set_active=true' \
--compressed
Add the application settings that are defined in the environment variables above.
If you have an AWS account and have already installed and configured the AWS CLI tool, you can easily deploy this application to API Gateway and Lambda via CloudFormation in a few minutes.
Instead of editing config.js
, take these steps:
- Copy
aws/config.example.sh
toaws/config.sh
- Edit the values in
aws/config.sh
, which correspond to the variables described above, plus these:StackName
: the name of the CloudFormation stack to createS3BucketArtifacts
: the name of an existing S3 bucket you have write access to, for storing deployment artifactsS3PrefixArtifacts
: the prefix to use within that S3 bucket for all deployment artifacts written
- Run
aws/deploy.sh
to create the CloudFormation stack and deploy your application, outputting the URL - (Optional) For a friendlier URL, log into the AWS web console and establish a custom domain pointing to the API Gateway stage deployed in step 3.
Node.js is required.
$ git clone https://github.com/outsideris/slack-invite-automation.git

Or, You can build a Docker image yourself.
$ git clone https://github.com/outsideris/slack-invite-automation.git
$ cd slack-invite-automation
$ docker build -t outsideris/slack-invite-automation .
$ docker run -it --rm -e COMMUNITY_NAME="YOUR-TEAM-NAME" -e SLACK_URL="YOUR-TEAM.slack.com" -e SLACK_TOKEN="YOUR-ACCESS-TOKEN" -p 3000:3000 outsideris/slack-invite-automation
