mf-tool

Indian MF Tool

A lightweight Node.js and TypeScript utility for fetching Indian Mutual Fund data from mfapi.in, including scheme details, NAVs, and historical data.

Features

• Fetch complete list of Indian Mutual Fund schemes
• Search for specific Mutual Fund schemes by name
• Get latest NAV for any Mutual Fund scheme
• Retrieve historical NAV data
• Automatic local caching for improved performance

Installation

npm install mf-tool

Quick Start

import { MfTool } from 'mf-tool';

// Initialize the tool
const mfTool = new MfTool();

// Example: Search for a mutual fund scheme
async function findScheme() {
  const schemes = await mfTool.findSchemaCodeReference('SBI Blue Chip');
  console.log(schemes);
}

// Example: Get NAV details for a specific scheme
async function getNavDetails() {
  const navDetails = await mfTool.getFundNavDetails('123456');
  console.log(navDetails);
}

API Reference

new MfTool()

Creates a new instance of the MF Tool.

updateSchemaCodes(forcePull?: boolean): Promise<void>

Updates the local cache of mutual fund scheme codes.

Parameter	Type	Default	Description
forcePull	boolean	false	When true, ignores local cache and fetches fresh data from API

findSchemaCodeReference(userInput: string): Promise<SchemaCodeReference[]>

Searches for mutual fund schemes that match the input string.

Parameter	Type	Description
userInput	string	Search term for mutual fund scheme names

Returns: Array of matching SchemaCodeReference objects

getAllSchemaCodeReference(): Promise<SchemaCodeReference[]>

Retrieves all available mutual fund schemes.

Returns: Array of all SchemaCodeReference objects

getFundNavDetails(schemaCode: string, needHistoric?: boolean): Promise<NavDetails>

Fetches NAV details for a specific mutual fund scheme.

Parameter	Type	Default	Description
schemaCode	string		The unique code of the mutual fund scheme
needHistoric	boolean	false	When true, includes historical NAV data

Returns: NavDetails object containing the NAV information

Example Usage

Finding a Mutual Fund Scheme

import { MfTool } from 'indian-mf-tool';

async function searchFund() {
  const mfTool = new MfTool();
  
  // Search for HDFC funds
  const hdcpFunds = await mfTool.findSchemaCodeReference('HDFC');
  
  // Print the first 5 results
  console.log(hdcpFunds.slice(0, 5));
}

searchFund();

Getting NAV Details

import { MfTool } from 'indian-mf-tool';

async function getNavInfo() {
  const mfTool = new MfTool();
  
  // First find the scheme code
  const schemes = await mfTool.findSchemaCodeReference('Axis Bluechip Fund');
  
  if (schemes.length > 0) {
    // Get NAV details for the first matching scheme
    const navDetails = await mfTool.getFundNavDetails(schemes[0].schemaCode);
    console.log(`Latest NAV: ${navDetails.data.nav}`);
    console.log(`Date: ${navDetails.data.date}`);
  }
}

getNavInfo();

Working with Historical Data

import { MfTool } from 'indian-mf-tool';

async function getHistoricalNav() {
  const mfTool = new MfTool();
  
  // Get scheme with historical data
  const schemeCode = '119551'; // Example scheme code
  const navDetails = await mfTool.getFundNavDetails(schemeCode, true);
  
  // Access historical data
  const historicalData = navDetails.data.navHistory;

  console.log(historicalData);
}

getHistoricalNav();

Data Types

SchemaCodeReference

interface SchemaCodeReference {
  schemaCode: string;
  schemeName: string;
}

Error Handling

import { MfTool } from 'indian-mf-tool';

async function handleErrors() {
  const mfTool = new MfTool();
  
  try {
    // Using an invalid scheme code
    const navDetails = await mfTool.getFundNavDetails('invalid-code');
    console.log(navDetails);
  } catch (error) {
    console.error('Error fetching NAV details:', error.message);
  }
}

handleErrors();
