Client side and Server side rendering of ejs template

Question

I always wanted to learn NodeJS to be able to run the same code on server and client side. I am using NodeJS with Express and EJS. So. I have a .ejs page with lot\'s of HTM

Answer 1

As per ejs templates documentation

var template = new EJS({
  text: `
    <ul>
      <% for(i = 0; i < the_list.length; i++) { %>
        <li>the_list[i]</li>
      <% } %>
    </ul>
  `
});
var html = template.render({ the_list: data });
document.getElementById('list-wrapper').innerHTML = html;

<div id="output"></div>
<script src="/assets/js/ejs.js"></script>
<script>
  let blogPosts = [
    {
        title: 'Perk is for real!',
        body: '...',
        author: 'Aaron Larner',
        publishedAt: new Date('2016-03-19'),
        createdAt: new Date('2016-03-19')
    },
    {
        title: 'Development continues...',
        body: '...',
        author: 'Aaron Larner',
        publishedAt: new Date('2016-03-18'),
        createdAt: new Date('2016-03-18')
    },
    {
        title: 'Welcome to Perk!',
        body: '...',
        author: 'Aaron Larner',
        publishedAt: new Date('2016-03-17'),
        createdAt: new Date('2016-03-17')
    }
];
      var html = ejs.render(`<% for(let i = 0; i < posts.length; i++) { %>
    <article>
        <h2><%= posts[i].title %></h1>
        <p><%= posts[i].body %></p>
    </article>
<% } %>`, {posts: blogPosts});
  // Vanilla JS:
  document.getElementById('output').innerHTML = html;
</script>

download ejs.js or ejs.min.js from latest version

This should work, looks like your problem was the relational operator '>' because it will never output something.

<ul>
    <% for(var i=0; i<the_list.length; i++) { %>
        <li>
            <a>
                <%= the_list[i]%>
            </a>
        </li>
    <% } %>
</ul>
