Named export available; avoid deep imports

MiddlewareConfig

✓ import type { MiddlewareConfig } from 'tango-app-api-middleware'

Type import for TypeScript users

Demonstrates basic Express integration with the middleware using an API key from environment.

import middleware from 'tango-app-api-middleware'; import express from 'express'; const app = express(); app.use(middleware({ apiKey: process.env.API_KEY ?? '' })); app.get('/api/example', (req, res) => { res.json({ message: 'Hello' }); }); app.listen(3000, () => console.log('Server running on port 3000'));

Debug

Known issues

breakingBreaking change in v3: package is now ESM-only, dropping CommonJS support.

fix

Use ES module imports; update Node.js to >=18.10.0.

affects: >=3.0.0

deprecatedDeprecated: `legacy` option in middleware config removed in v3.5.0.

fix

Remove `legacy` property from options object; use new `mode` property instead.

affects: >=3.5.0

gotchaMiddleware does not include default error handler; uncaught errors will crash the process unless manually caught.

fix

Wrap middleware usage in try-catch or use an Express error-handling middleware.

affects: >=3.0.0

breakingBreaking change in v3.2.0: `headers` option now requires object with `name` and `value` arrays instead of plain object.

fix

Update headers configuration to use `{ name: string, value: string }[]` format.

affects: >=3.2.0

Errors

Common errors & fixes

Error [ERR_REQUIRE_ESM]: require() of ES Module

Package is ESM-only; using CommonJS require() fails.

fix

Use import statement or dynamic import().

TypeError: Cannot read properties of undefined (reading 'apply')

Middleware invoked without required `apiKey` option.

fix

Provide the `apiKey` parameter in middleware configuration: `middleware({ apiKey: 'your-key' })`.

TypeError: middleware is not a function

Importing default export incorrectly; likely used named import for default.

fix

Use `import middleware from 'tango-app-api-middleware'` (default import).
