  1. Clone this repository, then copy the configuration file:
cp config/default.js config/config.development.js
  1. Install the dependencies:
npm install

Create the database

npm run database

Start the server

npm start


Secret key

Each deployment should have a different secret key. You want to set the secret key for generating password hashes and salts.

Set the secret key by using the TOWNSHIP_SECRET environment variable.

Default location of account and sqlite databases

Specify where you want data for the app (databases and also by default the archiver) to be located. By default, all the data will be stored in ./data. If you'd like the data to be stored somewhere else, add a data key:

  data: '/path/to/my/data'

Closed beta

To create a closed beta, add the whitelist key with the path to a newline-delimited list of emails allowed to sign up. Default value false allows anyone to register an account.

{ whitelist: '/path/to/my/list/of/folks.txt'}

folks.txt should have a list of valid emails, each separated by a new line character. For example:

[email protected]
[email protected]

Location of cached and archived dat data

You can set the location where dat data is cached on the filesystem. By default it is stored in the data directory (above), in the archiver subdirectory. You can change this by using the archiver key:

{ archiver: '/mnt1/bigdisk/archiver-data' }

Mixpanel account

The site will report basic information to Mixpanel if you have an account. It will by default use the environment variable MIXPANEL_KEY.

This can also be set in the configuration file by using the mixpanel key:

{ mixpanel: '<my-api-key-here>' }

Advanced password security

If you want to have advanced security for generating passwords, you can use ES512 keys, for example. Generate the keys using this tutorial and set their locations in the configuration file.

  township: {
    db: 'township.db',
    publicKey: path.join('secrets', 'ecdsa-p521-public.pem'),
    privateKey: path.join('secrets', 'ecdsa-p521-private.pem'),
    algorithm: 'ES512'
