Linktree Local Dev Loop

Overview

Local development workflow for Linktree link-in-bio API integration. Provides a fast feedback loop with mock link profiles, analytics, and appearance data so you can build social management tools without hitting the live Linktree API. Toggle between mock mode for rapid UI iteration and live mode for validating profile updates against the real Linktree platform.

Environment Setup

cp .env.example .env
# Set your credentials:
# LINKTREE_API_KEY=lt_xxxxxxxxxxxx
# LINKTREE_BASE_URL=https://api.linktr.ee/v1
# MOCK_MODE=true
npm install express axios dotenv tsx typescript @types/node
npm install -D vitest supertest @types/express

Dev Server

// src/dev/server.ts
import express from "express";
import { createProxyMiddleware } from "http-proxy-middleware";
const app = express();
app.use(express.json());
const MOCK = process.env.MOCK_MODE === "true";
if (!MOCK) {
  app.use("/v1", createProxyMiddleware({
    target: process.env.LINKTREE_BASE_URL,
    changeOrigin: true,
    headers: { Authorization: `Bearer ${process.env.LINKTREE_API_KEY}` },
  }));
} else {
  const { mountMockRoutes } = require("./mocks");
  mountMockRoutes(app);
}
app.listen(3005, () => console.log(`Linktree dev server on :3005 [mock=${MOCK}]`));

Mock Mode

// src/dev/mocks.ts — realistic link-in-bio profile and analytics responses
export function mountMockRoutes(app: any) {
  app.get("/v1/profile", (_req: any, res: any) => res.json({
    id: "usr_1", username: "janedoe", displayName: "Jane Doe", bio: "Designer & creator",
    links: [
      { id: "lnk_1", title: "Portfolio", url: "https://jane.design", position: 0, enabled: true },
      { id: "lnk_2", title: "Shop", url: "https://shop.jane.design", position: 1, enabled: true },
      { id: "lnk_3", title: "Newsletter", url: "https://jane.substack.com", position: 2, enabled: false },
    ],
  }));
  app.get("/v1/analytics", (_req: any, res: any) => res.json({
    totalViews: 12450, totalClicks: 3280, clickRate: 0.263,
    topLinks: [{ id: "lnk_1", title: "Portfolio", clicks: 1890 }],
  }));
  app.put("/v1/links/:id", (req: any, res: any) => res.json({ id: req.params.id, ...req.body, updatedAt: new Date().toISOString() }));
}

Testing Workflow

npm run dev:mock &                    # Start mock server in background
npm run test                          # Unit tests with vitest
npm run test -- --watch               # Watch mode for rapid iteration
MOCK_MODE=false npm run test:integration  # Integration test against real API

Debug Tips

• Linktree link ordering is zero-indexed — verify position field when reordering
• Analytics endpoints may return null for new links with no click data yet
• Use enabled: false to test hidden links without deleting them
• Check that url values include protocol (https://) or the API will reject them
• Rate limits are per-user — test with a dedicated dev account
