Template Rendering with res.render()¶

This page covers how res.render() passes data into rendered commands and templates.

For the complete method reference and practical examples, see the res.render() Guide.

Automatic Content Type Detection¶

res.render() sets the correct Content-Type from the file extension:

res.render("page.html")   // text/html
res.render("data.json")   // application/json
res.render("script.js")   // application/javascript
res.render("style.css")   // text/css
res.render("api.xml")     // application/xml
res.render("plain-text")  // text/plain

Data Passing and Template Context¶

Pass data using the second argument:

// Webapp URL: /webapp/showProfile?section=settings&view=compact

res.render("profile-template.html", {
  data: {
    user: user,
    profile: userProfile,
    preferences: userPrefs
  }
})

Inside the rendered template you can access:

• Custom fields from data (e.g. profile, preferences)
• params — URL query parameters ({ section: "settings", view: "compact" })
• Global TBL variables (Api, Bot, msg, request, etc.)
• user — only in user-based webhooks, not in public Webapp URLs
