res.sendfile in Node Express with passing data along

Question

Is there any way to redirect to an HTML file from a Node.JS application with something like: res.sendFile of express and pass a JSON data along to the html file?

Answer 1

Well, it's kinda old, but I didn't see any sufficient answer, except for "why not". You DO have way to pass parameters IN static file. And that's quite easy. Consider following code on your origin (using express):

    let data = fs.readFileSync('yourPage.html', 'utf8');
    if(data)
    res.send(data.replace('param1Place','uniqueData'));
    //else - 404

Now for example, just set a cookie, in yourPage.html, something like:

And you can plainly pull content of uniqueData from yourCookieName wherever you want in your js
