Node.js / Jade - How to precompile jade files and cache them?

Question

Frame: node.js / express.js / Jade

Question: in the production of env, when the jade file is issued by the jade express cache, so future renderings are faster.

When I run the node.js application, how can I precompile (or) pre-render (e.g. warm up) all the jade files so that it is already in the cache when requests start to come in ...

I can use folder recursion, I just need to know how to precompile (or) pre-render.

Is it possible?

Answer 1

Jade has pre-compilation and template caching.

http://jade-lang.com/api/

Just specify cache: true option jade.compileFile and repeat all the template files.

 var options = {cache: true}; // iterate/recurse over your jade template files and compile them jade.compileFile('./templates/foo.jade', options); // Jade will load the compiled templates from cache (the file path is the key) jade.renderFile('./templates/foo.jade');

If you don’t use any parameters, you can compile jade templates directly in HTML using grunt or gulp and make it monitor file changes

Try it on the command line: jade view/map-beacons.jade -D

If you need to use parameters, I would use something like Andrew Lavers answer.

compileFile returns a function that you can use to pass in parameters ie fn({ myJsVar: 'someValue' })

The command line also has a client option, but I did not find any benefit for this: jade view/map-beacons.jade -cD

I am making this decision, this code is outside of the http.createServer function

 let cache_index=jade.renderFile('index.jade'); 

and in reverse look

 res.statusCode = 200; res.setHeader('Content-Type', 'text/html'); res.end(cache_index); 

when using this server return server return to 1ms but without a solution server return index from 150 ms to 400 ms

result:

Image 2 without cache
