How to Use

You can choose from one of the following two methods to use this repository:

One-Click Deploy

Deploy the example using Vercel:

Clone and Deploy

Execute create-next-app with pnpm to bootstrap the example:

pnpm create next-app --example https://github.com/vercel/examples/tree/main/edge-middleware/feature-flag-split feature-flag-split

You'll need to have an account with Split. Once that's done, copy the .env.example file in this directory to .env.local (which will be ignored by Git):

cp .env.example .env.local

Then open .env.local and set the environment variables to match the ones in your Split dashboard. Your keys should be available under Workspace settings - API Keys, in the admin settings of your organization.

Set up environment variables

Copy .env.example to .env.local:

cp .env.example .env.local

Then fill it with the following information:

• Log in to the Split console and navigate to Profile -> Admin Settings -> API Keys -> SDK API Keys to retreive your SDK API Key.

• Install the Split Vercel Integration for your project. Then fill in .env.local with the provided Edge Config Item Key.

• You can find the Edge Config Connection String on vercel.com -> Storage -> [Your Edge Config] -> Projects. You can click Connect Project if your Edge Config is not connected to any project yet. This will automatically create a token for you and set it up as an environment variable on your project. Note that you still need to provide it to your .env.local file. Otherwise, click on Tokens in the sidebar and find the token you want to use. Then click on the three dots of and select Copy Connection String.

• You also need to create feature flags called New_Marketing_Page and New_About_Page. You can set the user targeting to Joe and Bobby in whatever configuration you'd like as those users are used by this example.

Next, run Next.js in development mode:

pnpm dev

Deploy it to the cloud with Vercel (Documentation).
