How do I use environment variables?

You might want to set environment variables and secrets in Proxyflare. Wrapping Proxyflare in a PagesFunction provides access to a Context with environment variables on ctx.env.

Environment variables can be managed from your Cloudflare Pages dashboard.

functions/_middleware.ts

import proxyflare from "@flaregun-net/proxyflare-for-pages"

const routes: Route[] = []

// Set API_SERVICE_TOKEN in your Pages dashboard.
type Env = { API_SERVICE_TOKEN: string }

export const onRequest: PagesFunction<Env>[] = [
  (ctx) =>
    proxyflare({
      config: {
        routes: [
          {
            from: { pattern: "proxyflare.works/api/*" },
            to: { url: "my-api.com" },
            headers: {
              request: `Bearer ${ctx.env.API_SERVICE_TOKEN}`,
            },
          },
        ],
      },
    })(ctx),
]
