I am getting a reference error in my node application

I'm new to express.js and node and am currently getting a reference error in my code, please do advise on how I should solve this? apparently the code cant find my reference to the "articles" constatn all though its defined.

Here is my author.ejs file

const router = express.Router()

router.get('/home', (req, res) => {
    const articles = [{
        title: 'test article',
        subtitle: 'test subtitle',
        createdAt: new Date(),
        lastModified: new Date()
    }]
    res.render('author', {author:articles})
})

router.get('/draft', (req, res) => {
   
    res.render('draft', {author:articles})
})
app.set('view engine', 'ejs');

module.exports=router

here is my author.js file

    <a href="/author/draft" class="btn btn-success">New Draft</a>

    <% articles.forEach(article => { %>
      <div class="card mt-4">
        <div class="card-body">
          <h4 class="card-title"><%= article.title %></h4>
          <div class="card-subtitle text-muted mb-2">
            <%= article.createdAt.toLocaleDateString() %>
          </div>
          <div class="card-text mb-2"><%= article.description %></div>
          <!--<a href="author/<%= article.slug %>" class="btn btn-primary">Read More</a>

articles is not defined
Solution

  • You use res.render('author', {author:articles}) to send the data.

    So, you need to use

    <% author.forEach(article => { %>

    instead of

    <% articles.forEach(article => { %>

    Or to be able to use articles you have to change

    res.render('author', {author:articles})

    to

    res.render('author', {articles:articles})

    Either one should make it work properly.
