Refacto service integrations

Databases

By default, Refacto will use an in-memory database. This means it cannot be load-balanced, and all data will be erased if the server is restarted or an update is deployed. To persist data and allow load-balancing, configure a real database:

MongoDB

You can specify the database connection string as:

DB_URL="mongodb://localhost:27017/refacto" ./index.js

The URL can also contain options, such as:

DB_URL="mongodb://localhost:27017/refacto?ssl=true" ./index.js

Installation

On macOS, MongoDB can be installed with:

brew install mongodb
brew services start mongodb

On Ubuntu, it can be installed with:

apt install mongodb

The configuration file will be created at /usr/local/etc/mongod.conf on macOS and /etc/mongod.conf on Ubuntu.

Note: MongoDB's default security model is enough for local development, but you should lock it down further in deployments. See the security documentation for details.

Redis

Redis is also supported for persisting data, but is experimental and not recommended for production deployments.

DB_URL="redis://localhost:6379/0" ./index.js

PostgreSQL

PostgreSQL is also supported for persisting data, but is not optimised for this type of data. For small deployments, it may be easier to securely configure PostgreSQL than MongoDB.

You must create a database for Refacto to use. The schema will be auto-generated when the app starts.

DB_URL="postgresql://localhost:5432/refacto" ./index.js

Authentication providers

Google sign in

You will need a Google client ID:

  1. Go to https://console.developers.google.com/apis
  2. Create a new project (if necessary)
  3. In the "Credentials" screen, find the auto-generated OAuth client entry (if it was not created automatically, create one manually with "Create credentials" → "OAuth client ID")
  4. Record the client ID (you will not need the client secret)
  5. Update the authorised JavaScript origins to match your deployment. e.g. for local testing, add http://localhost:5000
  6. Update the authorised redirect URIs to the same value, with /sso/google appended to the end.
  7. You may want to change the "Support email" listed under "OAuth consent screen", as this will be visible to users of your deployed app.

You can now invoke the application with the SSO_GOOGLE_CLIENT_ID environment variable set. This applies to both local testing and deployments. For example:

SSO_GOOGLE_CLIENT_ID="something.apps.googleusercontent.com" ./index.js

GitHub sign in

You will need a GitHub client ID:

  1. Go to https://github.com/settings/applications/new
  2. Set the "Homepage URL" to match your deployment. e.g. for local testing, use http://localhost:5000
  3. Set the "Authorization callback URL" to the same value, with /sso/github appended to the end.
  4. Record the client ID and client secret.

You can now invoke the application with the SSO_GITHUB_CLIENT_ID and SSO_GITHUB_CLIENT_SECRET environment variables set. This applies to both local testing and deployments. For example:

SSO_GITHUB_CLIENT_ID="idhere" SSO_GITHUB_CLIENT_SECRET="secrethere" ./index.js

GitLab sign in

You will need a GitLab client ID:

  1. Go to https://gitlab.com/profile/applications
  2. Set the "Redirect URI" to match your deployment with /sso/gitlab appended to the end. e.g. for local testing, this could be http://localhost:5000/sso/gitlab
  3. Untick the "confidential" option. You do not need to enable any scopes.
  4. Record the application ID (you will not need the secret).

You can now invoke the application with the SSO_GITLAB_CLIENT_ID environment variable set. This applies to both local testing and deployments. For example:

SSO_GITLAB_CLIENT_ID="idhere" ./index.js

To use a self-hosted GitLab deployment, you will also need to set the auth and token info URLs:

SSO_GITLAB_AUTH_URL="https://gitlab.example.com/oauth/authorize" \
SSO_GITLAB_TOKEN_INFO_URL="https://gitlab.example.com/oauth/token/info" \
SSO_GITLAB_CLIENT_ID="idhere" \
./index.js

Other Integrations

Giphy

You will need a Giphy API key:

  1. Go to https://developers.giphy.com/dashboard/?create=true
  2. Log in and provide an application name and description
  3. Record the API key.

You can now invoke the application with the GIPHY_API_KEY environment variable set. This applies to both local testing and deployments. For example:

GIPHY_API_KEY="keyhere" ./index.js

haveibeenpwned Password Database

The haveibeenpwned password database is automatically used for checking user-provided passwords (k-Anonymity ensures no passwords are leaked to the external service).

No configuration is required.

If you wish to disable this integration, you can specify a blank URL:

PASSWORD_CHECK_BASE_URL="" ./index.js
