Graph API Token Manager

Graph API Token Manager is a Node.js package that provides functionality to manage Facebook Graph API tokens. It can be used to exchange a code for an access token and to exchange a short-lived access token for a long-lived access token.

Installation

You can install the package using npm:

npm install graph-api-token-manager

Usage

First, create a new instance of the TokenManager class:

const TokenManager = require('graph-api-token-manager');
const tokenManager = new TokenManager();

Exchanging a code for an access token To exchange a code for an access token, use the exchangeCodeForAccessToken method:

const code = 'your_obtained_code';
const longLivedAccessToken = await tokenManager.exchangeCodeForAccessToken(code);
console.log(`Long-lived access token: ${longLivedAccessToken}`);

Exchanging a short-lived access token for a long-lived access token To exchange a short-lived access token for a long-lived access token, use the exchangeShortLivedForLongLivedAccessToken method:

const shortLivedAccessToken = 'your_short_lived_access_token';
const longLivedAccessToken = await tokenManager.exchangeShortLivedForLongLivedAccessToken(shortLivedAccessToken);
console.log(`Long-lived access token: ${longLivedAccessToken}`);

Example

Here is an example of how to use the package:

const TokenManager = require('graph-api-token-manager');

(async () => {
  try {
    const tokenManager = new TokenManager();

    // Exchange a code for an access token
    const code = 'your_obtained_code';
    const longLivedAccessToken = await tokenManager.exchangeCodeForAccessToken(code);
    console.log(`Long-lived access token: ${longLivedAccessToken}`);

    // Exchange a short-lived access token for a long-lived access token
    const shortLivedAccessToken = 'your_short_lived_access_token';
    const longLivedAccessToken2 = await tokenManager.exchangeShortLivedForLongLivedAccessToken(shortLivedAccessToken);
    console.log(`Long-lived access token: ${longLivedAccessToken2}`);
  } catch (error) {
    console.error(`Error: ${error.message}`);
  }
})();
