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();
const code = 'your_obtained_code';
const longLivedAccessToken = await tokenManager.exchangeCodeForAccessToken(code);
console.log(`Long-lived access token: ${longLivedAccessToken}`);
const shortLivedAccessToken = 'your_short_lived_access_token';
const longLivedAccessToken2 = await tokenManager.exchangeShortLivedForLongLivedAccessToken(shortLivedAccessToken);
console.log(`Long-lived access token: ${longLivedAccessToken2}`);
} catch (error) {
