Change route dynamically in express by extracting route path from json file-CodePudding

I'm trying to change my route dynamically in express for which the exact link is stored in a json file. My json is stored in articles.js looking something like this:

  title: 'title1',
  link: 'title2',
  creator: 'user1',
  createdAt: '17/10/2021',
  description: 'Test description',
  publish: 'True',
  text: 'This is a sample text'
},
{
  title: 'title2',
  link: 'title2',
  creator: 'user3',
  createdAt: '17/10/2021',
  description: 'Test description',
  publish: 'True'
},
{
  title: 'title3',
  link: 'title3',
  creator: 'user2',
  createdAt: '17/10/2021',
  description: 'Test description',
  publish: 'True'
}]

exports.articles = articles;

During my get-route I dynamically wnat to render to blog_articles page changing the hyperlink to route \theme\title1, \theme\title2 etc. dynamically. My express routes are defined like this:

const router = express.Router()

const Articles = require('../articles/articles');

router.get("/", async (req, res) => {
    const articles = await Object.values(Articles.articles).filter(all => all.publish ==='True');
    res.render("theme", {articles: articles});
});


router.get("/:link", async (req, res) => {
    var link = req.params.articles.link
    const articles = await Object.values(Articles.articles).filter(all => all.publish ==='True');
    res.render("blog_articles", {articles: articles.link});


    res.send(articles.link);
    res.send(req.params.id);
    //const articles = await Object.values(Articles.articles).filter(all => all.publish 
});

Edit: Here is the theme.ejs:

<!DOCTYPE html>

CodePudding user response：

Use find to get the article you need:

router.get("/:link", async (req, res) => {
    var link = req.params.link
    const article = Object.values(Articles.articles)
      .filter(all => all.publish ==='True')
      .find(article => article.link === link)
    res.render("blog_articles", {articles: article.link});

    // You have already sent a response, following code is useless
    // res.send(articles.link);
    // res.send(req.params.id);
});
