On Demand Pre-Render

[Debdut]

Do you want to request a feature or report a bug?

Feature
On Demand Pre-Render

What is the current behaviour?
I can pre-render only while building using

preact build --prerenderUrls ./prerender.js

After the build is created, I am not able to pre-render without deleting previous build.

I am building an E-commerce site, when new products are added, I want to pre-render them and only those product pages, keeping rest of my previous build. Is it possible to create a system, when new pages are pre-rendered on demand?

I don't want SSR for sure!

This is a very interesting idea. @developit we should probably do this

@Debdut curious about your use case, where and when would you like to trigger this additional prerendering?

• Where? Would this be on the CI server or on the actual web server?
• When? Would you trigger this when you add an item via some webhook or when the request comes?

[Debdut]

I trigger this when a request comes in

[Debdut]

If you create partial builds which can attach to previous build without deleting it, it works too

[ForsakenHarmony]

I trigger this when a request comes in

So basically cached SSR?

[Debdut]

Yeah, thanks for the terminology

[prateekbh]

I wonder what would the setup look like?

• A request comes in, you check if the URL is already pre-rendered
• You call a function in preact-cli
• It generates the file for this and future requests
• Future requests serve from previously prerendered file?

or

• Introduce a server which does SSR for you and serve stale responses upto a given time

First one sounds better
