Snyk Apps Demo

This is a demo app that can be used as a guide on how to create Snyk Apps. This repository contains a simple implementation of a Snyk App written in Typescript, NodeJS and EJS.

Important Note

As mentioned above this demo Snyk App has been written in Typescript, NodeJS and EJS, but developers can use any preferred language or framework of their choice to create a Snyk App.

Also important to mention that we are using passportjs for the authentication process with our very own passport strategy @snyk/passport-snyk-oauth2. Developers can use any available oauth2 client of their choice or write the authentication code from scratch following our Snyk Apps Docs.

Requirements:

  • node version 10 or greater
  • npm version 6 or greater

Getting started:

  • Clone the repo $ git clone https://github.com/snyk/snyk-apps-demo
  • Install all the required dependencies: $ npm ci or npm install

Create a new Snyk App:

The first thing you need to do is create an app. If you haven't already created a Snyk App, you can do so via our create script:

$ npm run create-app -- --authToken=$token --orgId=$id --scopes=$scopes --name="$name"

Ex:

$ npm run create-app -- --authToken=some-token --orgId=some-snyk-org-id --scopes=org.read org.project.read org.project.snapshot.read --name=test-snyk-app

or with redirectUris

$ npm run create-app -- --authToken=some-token --orgId=some-snyk-org-id --redirect-uris=https://your-domain/callback --scopes=org.read org.project.read org.project.snapshot.read --name=test-snyk-app

(note the extra -- between create-app and the parameters)

  • authToken(Required/String): your personal Snyk auth token, obtained from your account settings page
  • orgId (Required/String): the organization id that you want to own the Snyk App (obtained by clicking the cog in the upper right corner of the Snyk console)
  • redirectUris (Optional/String Array): a space separated list of redirect uris for your app, defaults to http://localhost:3000/callback when no input provided
  • scopes (Required/String Array): a space separated list of scopes you want your App to be able to request at install time (see Snyk Apps: Requesting scopes for allowed values)
  • name (Required/String): the friendly name of your Snyk App

This will register your new app with Snyk and create the .env file (see below) with your new CLIENT_ID, CLIENT_SECRET, REDIRECT_URI, SCOPES and ENCRYPTION_SECRET. Keep these values secure!

  • CLIENT_ID: the client id associated with your Snyk App
  • CLIENT_SECRET: super secret client secret associated with your Snyk App
  • REDIRECT_URI: the redirect uri used by your Snyk App
  • SCOPES: the space-separated list of scopes for your Snyk App
  • ENCRYPTION_SECRET: secret encryption key used by the demo app to encrypt sensitive data

Running the Demo Snyk App:

  1. Run the following command to compile TypeScript into JavaScript

    $ npm run build

  2. Once the TypeScript has been compiled to JavaScript(into ./dist directory) run

    $ npm run dev

  3. Go to localhost:3000 to confirm that the app is running successfully

The .env File:

The .env file is used to store environmental variables. Ensure this remains secret! If you've already created a Snyk App, you can copy .env.example and set the values.
