how to make a login with facebook page with node js code example

Example 1: facebook integration in node.js

const request = require('request-promise');

module.exports = (app) => {

  // you'll need to have requested 'user_about_me' permissions
  // in order to get 'quotes' and 'about' fields from search
  const userFieldSet = 'name, link, is_verified, picture';
  const pageFieldSet = 'name, category, link, picture, is_verified';


  app.post('/facebook-search', (req, res) => {
    const  { queryTerm, searchType } = req.body;

    const options = {
      method: 'GET',
      uri: 'https://graph.facebook.com/search',
      qs: {
        access_token: config.user_access_token,
        q: queryTerm,
        type: searchType,
        fields: searchType === 'page' ? pageFieldSet : userFieldSet
      }
    };

    request(options)
      .then(fbRes => {
// Search results are in the data property of the response.
// There is another property that allows for pagination of results.
// Pagination will not be covered in this post,
// so we only need the data property of the parsed response.
        const parsedRes = JSON.parse(fbRes).data; 
        res.json(parsedRes);
      })
  });
}

Example 2: facebook integration in node.js

app.get('/facebook-search/:id', (req, res) => {
    
  // you need permission for most of these fields
  const userFieldSet = 'id, name, about, email, accounts, link, is_verified, significant_other, relationship_status, website, picture, photos, feed';
    
  const options = {
    method: 'GET',
    uri: `https://graph.facebook.com/v2.8/${req.params.id}`,
    qs: {
      access_token: user_access_token,
      fields: userFieldSet
    }
  };
  request(options)
    .then(fbRes => {
      res.json(fbRes);
    })
})
