Stack

Overview

Quickstart

The simplest way to try out this stack is to test it out locally and traverse through code files to understand how each component work. Here are the steps to get started.

1. Fork and Clone repo

Fork the repo to your Github account, then run the following command to clone the repo:

git clone [email protected]:[YOUR_GITHUB_ACCOUNT_NAME]/ai-getting-started.git

2. Install dependencies

cd ai-getting-started
npm install

3. Fill out secrets

cp .env.local.example .env.local

a. Clerk Secrets

Go to https://dashboard.clerk.com/ -> "Add Application" -> Fill in Application name/select how your users should sign in -> Create Application Now you should see both NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY and CLERK_SECRET_KEY on the screen clerk

b. OpenAI API key

Visit https://platform.openai.com/account/api-keys to get your OpenAI API key

c. Replicate API key

Visit https://replicate.com/account/api-tokens to get your Replicate API key

NOTE: By default, this template uses Pinecone as vector store, but you can turn on Supabase pgvector easily. This means you only need to fill out either Pinecone API key or Supabase API key.

d. Pinecone API key

  • Create a Pinecone index by visiting https://app.pinecone.io/ and click on "Create Index"
  • Give it an index name (this will be the environment variable PINECONE_INDEX)
  • Fill in Dimension as 1536
  • Once the index is successfully created, click on "API Keys" on the left side nav and create an API key: copy it to PINECONE_API_KEY

e. Supabase API key

  • Create a Supabase instance here; then go to Project Settings -> API
  • SUPABASE_URL is the URL value under "Project URL"
  • SUPABASE_PRIVATE_KEY is the key starts with ey under Project API Keys
  • Now, you should enable pgvector on Supabase and create a schema. You can do this easily by clicking on "SQL editor" on the left hand side on supabase UI and then clicking on "+New Query". Copy paste this code snippet in the SQL editor and click "Run".

f. Arcjet key

Visit https://app.arcjet.com to sign up for free and get your Arcjet key.

4. Generate embeddings

There are a few markdown files under /blogs directory as examples so you can do Q&A on them. To generate embeddings and store them in the vector database for future queries, you can run the following command:

If using Pinecone

Run the following command to generate embeddings and store them in Pinecone:

npm run generate-embeddings-pinecone

If using Supabase pgvector

In QAModel.tsx, replace /api/qa-pinecone with /api/qa-pg-vector. Then run the following command to generate embeddings and store them in Supabase pgvector:

npm run generate-embeddings-supabase

5. Run app locally

Now you are ready to test out the app locally! To do this, simply run npm run dev under the project root.

6. Deploy the app

Deploy to fly.io

  • Register an account on fly.io and then install flyctl
  • Run fly launch under project root -- this will generate a fly.toml that includes all the configurations you will need
  • Run fly deploy --ha=false to deploy the app -- the --ha flag makes sure fly only spins up one instance, which is included in the free plan. You also want to run fly scale memory 512 to scale up the fly vm memory for this app.
  • For any other non-localhost environment, the existing Clerk development instance should continue to work. You can upload the secrets to Fly by running cat .env.local | fly secrets import
  • If you are ready to deploy to production, you should create a prod environment under the current Clerk instance. For more details on deploying a production app with Clerk, check out their documentation here. Note that you will likely need to manage your own domain and do domain verification as part of the process.
  • Create a new file .env.prod locally and fill in all the production-environment secrets. Remember to update NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY and CLERK_SECRET_KEY by copying secrets from Clerk's production instance -cat .env.prod | fly secrets import to upload secrets
