The 'app' package is a minimalistic JavaScript web application development framework designed for Node.js, building upon the Connect middleware. Originating around 2011 (as indicated by the copyright and early version `0.1.0`), it aimed to provide a simple, routes-based approach to handling HTTP requests. Its design is reminiscent of early Node.js frameworks, focusing on direct request/response handling and middleware chaining via Connect. Due to its age, it is no longer actively maintained and should be considered for historical reference or extremely niche legacy projects rather than new development. It predates modern Node.js features, async/await, and popular frameworks like Express.js or Fastify, which offer more robust features and active communities.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

App
✓ const App = require('app');
✗ import { App } from 'app'; import App from 'app';
This package predates ES Modules and exclusively uses CommonJS `require()` syntax. The primary export is the `App` constructor.
App Instance
✓ const app = new (require('app'))();
A common pattern is to immediately instantiate the 'App' constructor after requiring it. This is not a distinct import but a usage pattern of the main export.
Require for side effects (less common)
✓ require('app');
✗ import 'app';
While less common for frameworks, some CommonJS modules might be imported purely for side effects or to register globals. Using `import 'app'` for this purpose is incorrect for this CJS-only package.

Demonstrates the basic setup, defines a simple route for the root path, and starts the HTTP server to respond with 'Hello World'.

const App = require('app'); const app = new App(); // Define a route for the root path app.routes({ '': function (req, res, next){ res.send('Hello World'); } }); // Start the server on port 3000 const PORT = process.env.PORT ?? 3000; app.listen(PORT, () => { console.log(`App listening on http://localhost:${PORT}`); console.log('Open your browser to see "Hello World"'); });
Debug
Known issues
breakingThis package is explicitly abandoned and has not been updated since circa 2011 (version 0.1.0). It is not compatible with modern Node.js versions or contemporary JavaScript features (e.g., async/await, ES Modules).
fix
Migrate to an actively maintained and modern Node.js web framework like Express, Fastify, or Koa. Do not use for new development.
affects: >=0.1.0
gotchaThe framework exclusively uses CommonJS (`require()`) for module imports and exports. It does not support ES Modules (`import`/`export` syntax), which became standard much later.
fix
Ensure your project uses CommonJS syntax throughout or use a build tool like Webpack or Rollup configured for CJS output if integrating into a legacy system.
affects: >=0.1.0
breakingGiven its age and abandonment, 'app' likely depends on extremely outdated versions of 'Connect' and other libraries, which may contain known security vulnerabilities and are not patched. Using it in production is a significant security risk.
fix
Do not use in production environments. Audit all transitive dependencies for vulnerabilities if used for legacy maintenance, or migrate to a secure, modern framework with active community support.
affects: >=0.1.0
gotchaThe API is callback-based and does not natively support Promises or async/await, aligning with Node.js patterns from the early 2010s. Integrating it with modern asynchronous JavaScript can be challenging.
fix
Wrap callback-based functions in Promises manually using `util.promisify` or custom wrappers if integrating with modern async code, or consider rewriting routes using a contemporary framework.
affects: >=0.1.0
Errors
Common errors & fixes
TypeError: App is not a constructor
Attempting to instantiate 'App' after importing it incorrectly using ES module syntax (e.g., `import App from 'app';`) or named destructuring from a CJS module that exports a single constructor.
fix
Use CommonJS require syntax for `App`: `const App = require('app');`
SyntaxError: Cannot use import statement outside a module
Attempting to use ES module `import` syntax in a file that Node.js interprets as a CommonJS module (e.g., a `.js` file without `"type": "module"` in `package.json`, or an older Node.js environment).
fix
Replace `import` statements with CommonJS `require()` syntax: `const App = require('app');`
Error: Cannot find module 'connect'
The 'connect' package, a direct dependency of 'app', is not installed or not resolvable in the project's `node_modules`.
fix
Install 'connect' explicitly: `npm install connect` to ensure it is available for 'app'.
