Deploy your own

Step 1: Clone the repository

1. Clone the repository:

   git clone https://github.com/upstash/purple-squirrel.git
   cd purple-squirrel

Alternatively you can use the Vercel Deploy Button:

Step 2: Connect your mailbox

Note: This tutorial will be based on Gmail, but you can set up an IMAP connection with any other provider. We recommend creating a separate email like ps@company.com and forwarding job mails there. You can also create a folder like JOBS and configure the application to read from that folder in the setup step.

1. Complete the following steps described in this tutorial.
   • Step 1: Turn on Less secure apps
   • Step 2: Create and use App Passwords

   • IMAP_USERNAME: Your mail address
   • IMAP_PASSWORD: App Password you generated

Step 4: Set up Upstash QStash

1. Switch to QStash tab in Upstash Console
2. Fill the following environment variables in your .env file, which can be found and copied in your QStash page:
   • QSTASH_URL
   • QSTASH_TOKEN
     

QStash free plan has a limit of 500 messages per day. This will limit your mail pipeline to approximately 200 applicants per day. We recommend upgrading to the pay as you go plan. See QStash Pricing for more information.

Step 5: Set up uploadthing

Step 6: Set OpenAI API key

Step 7: Set up Basic Auth

1. Decide if you want Basic Auth in your application, and set the following environment variable in your .env file:
   BASIC_AUTH_ENABLED=true
   or
   BASIC_AUTH_ENABLED=false
   
2. If you want Basic Auth, fill the following environment variables in your .env file:
   • BASIC_AUTH_USERNAME
   • BASIC_AUTH_PASSWORD

Step 8: Deploy & Setup

   vercel

2. Go to your project at Vercel Dashboard for the next steps.
3. Learn the Production Domain of your application from the Project tab.
   
4. Go to Settings -> Environment Variables, copy and paste your .env file.
5. Fill the following environment variable with the Production Domain (Not the Deployment URL) of your application:
   • NEXT_PUBLIC_URL: Production Domain of your application (e.g. https://your-app.vercel.app)
6. Go to the Deployments tab and redeploy your application.
   
7. Visit https://your-app.vercel.app/setup to set up your application.
   

→ Your application is ready to use!

Local development

A local tunnel is required in local development since QStash requires a publicly available API to send messages to. This tutorial is based on localtunnel.me but you can use any service of your choice.

Step 1: Create a local tunnel

npx localtunnel --port 3000

Step 2: Fill environment variables

Copy the output URL and fill the following environment variable in .env.local

LOCAL_TUNNEL_URL=<YOUR_URL>

Fill the rest of the environment variables in .env.local as described in the Deploy your own section.

Step 3: Install dependencies & run the project

npm install
npm run dev

Step 4: Setup

1. Visit http://localhost:3000/setup to set up your application.
   

→ Your application is ready to use!

In local development, mail pipeline is triggered only once instead of creating a schedule since local server is not expected to be always available.
