How do I render an EJS template file in Node.js?

Question

I\'m using Node.js and trying to render an EJS template file. I figured out how to render strings:

    var http = requ         


        

Answer 1

There's a synchronous version of this pattern that tightens it up a little more.

var server = http.createServer(function(req, res) {
    var filePath = __dirname + '/sample.html';
    var template = fs.readFileSync(filePath, 'utf8');
    res.end(ejs.render(template,{}));
});

Note the use of readFileSync(). If you specify the encoding (utf8 here), the function returns a string containing your template.

Use ejs.renderFile(filename, data) function with async-await.

To render HTML files.

const renderHtmlFile = async () => {
    try {
        //Parameters inside the HTML file
        let params = {firstName : 'John', lastName: 'Doe'};
        let html = await ejs.renderFile(__dirname + '/template.html', params);
        console.log(html);
    } catch (error) {
        console.log("Error occured: ", error);
    }
}

To render EJS files.

const renderEjsFile = async () => {
    try {
        //Parameters inside the HTML file
        let params = {firstName : 'John', lastName: 'Doe'};
        let ejs = await ejs.renderFile(__dirname + '/template.ejs', params);
        console.log(ejs);
    } catch (error) {
        console.log("Error occured: ", error);
    }
}
