Read files with Node.js

There are a couple of ways to read files with node. The easiest way is to readFileSync(). This is a blocking script meaning that everything stops until the file is loaded.

const fs = require('fs');
 function getFileContents = (filePath)=> {
    let fileContents =  fs.readFileSync(filePath) 
    fileContents = JSON.parse(fileContents)
}

function writeFileContents = (filePath, data )=> {
    let fileContents = JSON.parse(fs.readFileSync(filePath))
    // assuming data is an object being passed
     fileContents.push(data)
     // convert the object to json
     fileContents = JSON.stringify(fileContents)
     // write file and data
     fs.writeFileSync(fs.readFileSync(filePath), fileContents)
}

EJS Templates

If the user email validates then we will grant access to the dashboard. Grab a new copy of the data folder from the teams folder. There is a file called users.json. That is the file mimics a database. We will read this file and see if the provided email matches the one in the users.json file.

  npm install ejs

Now lets configure ejs as the templating engine we are going to use with our project.

const ejs = require('ejs')
app.set('view engine', 'ejs');
app.set('views', path.join(__dirname, './views'));
