Run with Docker

See docker image by Xqua

Development Setup

You need a recent Node JS version (4+) installed and JSPM 0.17 Beta (npm install jspm@beta -g).

  1. git clone and cd teamchatviz.
  2. npm install - install server npm dependencies.
  3. cd client && npm install && jspm install - install client dependencies.
  4. cd ...
  5. Create .env file with the following content:
SLACK_CLIENT_ID="<client id of your slack app>"
SLACK_CLIENT_SECRET="<slack app secret>"
DATABASE_URL="<postgresql database URL e.g. postgres://teamchatviz:teamchatviz@localhost/teamchatviz>"

If PUBLIC === true the data loaded into the system will be public and will not require authentication via Slack. If ANONYMIZE === true the data loaded into the system will be replaced with the fake data using Faker.js. Anonymization will happen only on the initial data loading and before the data reaches the database.

If PUBLIC === true, Add to Slack button on the Main page is hidden and login is disabled. If you change the PUBLIC setting for an existing instance, the changes will apply only after a restart of the server.

  1. Create database as described in the next section and apply database migration by running npm run up.
  2. npm start - start the server.
  3. Open http://localhost:$PORT in your browser.

Create a PostgreSQL database

In order to create a database in PostgreSQL you need to start psql client. On Linux systems you can run sudo -u postgres psql for this. On OS X you can start it via the UI of

Then you may run the following commands to create a user called teamchatviz with the password teamchatviz and a database called teamchatviz:

CREATE DATABASE teamchatviz;
ALTER USER teamchatviz VALID UNTIL 'infinity';
ALTER DATABASE teamchatviz OWNER TO teamchatviz;
GRANT ALL ON DATABASE teamchatviz TO teamchatviz;
\c teamchatviz
ALTER SCHEMA public OWNER TO teamchatviz;


npm test
