NodeBoost: JIT Compilation Middleware for Node.js

NodeBoost is a Just-In-Time (JIT) Compilation Middleware for Node.js that aims to improve the performance of critical sections of your Node.js applications.

Features

• Selective JIT compilation of critical functions.
• Runtime profiling and tracking of function execution times.
• Debug mode for detailed logging during function execution.
• Customizable compilation options to fit your application's needs.

Installation

To install NodeBoost in your Node.js project, use NPM:

npm install nodeboost

Usage

Marking a Function for JIT Compilation

const express = require('express');
const { markForJIT, jitMiddleware, profileFunctionExecution, getProfileData, setDebugMode, isDebugMode, preWarmCompiledFunctions } = require('nodeboost');

const app = express();

function expensiveCalculation(input) {
  let result = 0;
  for (let i = 1; i <= input; i++) {
    result += i;
  }
  return result;
}

markForJIT(expensiveCalculation, { strategy: 'aggressive', sampleArgs: [1000000] });

app.use(jitMiddleware);

app.get('/', (req, res) => {
  const startTime = Date.now();
  const result = expensiveCalculation(1000000);
  const executionTime = Date.now() - startTime;
  profileFunctionExecution(expensiveCalculation, [1000000], result, executionTime);
  if (isDebugMode()) {
    console.log(`Debug Mode: Executed function ${expensiveCalculation.name} in ${executionTime}ms`);
  }
  res.send(`Result: ${result} (Execution Time: ${executionTime}ms)`);
});

app.get('/profile', (req, res) => {
  const profileData = getProfileData();
  res.json(profileData);
});

app.get('/toggle-debug', (req, res) => {
  const debug = req.query.debug === 'true';
  setDebugMode(debug);
  res.send(`Debug Mode: ${debug}`);
});

app.get('/pre-warm', (req, res) => {
  preWarmCompiledFunctions();
  res.send(`Pre-warmed JIT-compiled functions.`);
});

const PORT = process.env.PORT || 3000;
app.listen(PORT, () => {
  console.log(`Server is running on port ${PORT}`);
});
