About Modular JavaScript and Fi-Plan.in

In their own words, as submitted to SaaSHub.

Modular JavaScript
Fi-Plan.in

No description of Modular JavaScript yet.

Markdown allowed. Ye paste karo: Fi-Plan is a month-by-month financial simulator for Indian salaries — not another expense tracker. Most tools tell you what already happened. Fi-Plan shows you what's possible: it models your income, spending, EMIs, SIPs, salary jumps and taxes for up to 50 years...

Features and specs

What each product offers, as listed by its team.

Modular JavaScript 5 features
Fi-Plan.in 9 features
  • Improved Code Organization
    Modular JavaScript allows developers to break down code into smaller, manageable modules. This enhances code readability and maintainability by organizing related functionality together.
  • Code Reusability
    Modules encourage reusability by allowing the same piece of code to be used across different projects or multiple areas of the same application, reducing redundancy.
  • Scalability
    As the application grows, managing code becomes easier with modular JavaScript. Each module can be developed, tested, and maintained independently, making the codebase more scalable.
  • Encapsulation
    Modules provide encapsulation, preventing variables and functions from polluting the global namespace. This reduces the risk of naming conflicts and bugs.
  • Improved Testing
    With code organized into discrete modules, writing unit tests becomes more straightforward. Each module can be tested individually, leading to more reliable and maintainable tests.

Possible disadvantages

  • Increased Complexity
    Introducing modularity can add complexity to the build process, as it often requires module loaders or bundlers (like Webpack or Browserify) to manage dependencies.
  • Overhead
    For smaller projects, using a modular approach might be overkill, introducing unnecessary overhead in terms of setup, configuration, and code management.
  • Learning Curve
    Developers unfamiliar with modular JavaScript may face a learning curve, especially when dealing with module patterns, loaders, and bundlers.
  • Dependency Management
    Relying on multiple modules can lead to complex dependency chains, making it challenging to track and resolve dependencies across different modules.
  • Performance Overhead
    Modular JavaScript can introduce performance overhead if not managed properly, such as loading many small modules individually, leading to increased HTTP requests.
  • 50-year month-by-month simulation
    Projects income, expenses, loans, SIPs and inflation monthly for up to 50 years.
  • Indian tax engine
    Models old and new income-tax regimes, HRA, deductions, 87A and surcharge.
  • Loans & prepayments
    Real EMI amortization; prepayments shorten the loan; refinance analysis.
  • Investments & assets
    FDs, bonds, PPF, gold, equity, mutual funds, real estate with SIP step-ups.
  • FIRE number & FI date
    4% rule corpus, savings rate and time-to-FI from your own numbers.
  • What-if scenarios
    Test prepay-vs-invest, salary jumps, big purchases; compare two plans side by side.
  • Templates & sharing
    Start from ready templates; share plans and an annual review card.
  • AI assistant + MCP
    Ask in plain language; run the same engine from Claude, ChatGPT or Cursor.
  • Encrypted at rest
    Financial data encrypted; no broker passwords or linked credentials.

Analysis

Overall verdict

  • Modular JavaScript (mjavascript.com) is a solid resource for developers looking to learn best practices around modular design patterns in JavaScript, though its value depends on your current skill level and how current the content remains given the fast pace of JS ecosystem changes.

Why this product is good

  • Focuses specifically on modularity, a critical but often overlooked aspect of scalable JavaScript development
  • Covers practical patterns for organizing code, managing dependencies, and structuring larger applications
  • Can help bridge the gap between basic JavaScript knowledge and professional-grade architecture skills
  • Often includes real-world examples rather than purely theoretical concepts
  • Useful for understanding module systems like CommonJS, ES Modules, and build tool configurations

Recommended for

  • Intermediate JavaScript developers wanting to level up their code organization skills
  • Developers transitioning from simple scripts to larger, maintainable applications
  • Teams looking to establish consistent modular coding standards
  • Self-taught programmers seeking structured guidance on architecture
  • Backend or frontend developers working with Node.js or modern JS frameworks who need better module management practices

Questions & Answers

As answered by people managing Modular JavaScript and Fi-Plan.in.

What makes your product unique?

Fi-Plan.in's answer:

Most tools tell you what already happened. Fi-Plan is a month-by-month financial simulator for Indian salaries — it projects income, taxes, EMIs, SIPs and net worth up to 50 years, so you can see when money gets tight and when financial independence arrives. The same engine powers a free API and MCP server, so AI assistants (Claude, ChatGPT, Cursor) run the exact same numbers.

Why should a person choose your product over its competitors?

Fi-Plan.in's answer:

India-specific by design: income-tax regimes, HRA and deductions, real EMI amortization with prepayments, step-up SIPs and rupee-first reporting — modelled month by month, not year-end estimates. It answers forward-looking questions ("prepay or invest?", "when can I retire?", "what if my salary jumps 20%?") from one consistent engine. Free to start, encrypted at rest, no broker passwords.

How would you describe the primary audience of your product?

Fi-Plan.in's answer:

Indian salaried professionals (28–40, metro, roughly ₹12L–₹60L income) who plan seriously for FIRE/retirement, plus NRIs planning a return. Tech-comfortable users who like running real scenarios either in the app or through an AI assistant.

Which are the primary technologies used for building your product?

Fi-Plan.in's answer:

Next.js (App Router) and TypeScript, React on the front end, MongoDB for storage, and a pure TypeScript calculation engine shared by the web app, the public REST API and the MCP server. Deployed on Vercel, encrypted at rest, with OAuth and MCP for AI-assistant access.

Who are some of the biggest customers of your product?

Fi-Plan.in's answer:

  • No public customers yet -Fi-Plan is an early, free product open to individual users (personal FIRE/retirement planning).

What's the story behind your product?

Fi-Plan.in's answer:

Fi-Plan started from personal experience, not a market study. After my family's business nearly collapsed, I rebuilt my finances around a layered foundation - save first (10% emergency, 40% savings, 50% investment), funding each layer before the next, then invest. It worked, but tracking it lived in spreadsheets. So my co-founder Utkarsh Pandey and I turned that system into a product: a way to quantify exactly how much money you'll have at any point and simulate income, expenses, loans, inflation and returns month by month. That became Fi-Plan.
