Install

npm:

npm install cache-pug-templates

yarn:

yarn add cache-pug-templates

Usage

Basic

const path = require('path');
const CachePugTemplates = require('cache-pug-templates');

const views = path.join(__dirname, 'views');

const cache = new CachePugTemplates({ views });
cache.start();

Koa

const path = require('path');
const Koa = require('koa');
const CachePugTemplates = require('cache-pug-templates');

const app = new Koa();

// optional (e.g. if you want to cache in non-production)
// app.cache = true;

// note that koa requires us to specify a
// path name for the views directory
const views = path.join(__dirname, 'views');

app.listen(3000, () => {
  const cache = new CachePugTemplates({ app, views });
  cache.start();
});

Express

const path = require('path');
const express = require('express');
const CachePugTemplates = require('cache-pug-templates');

const app = express();

// optional (by default express defaults to `./views`)
// app.set('views', path.join(__dirname, 'views'));

app.set('view engine', 'pug');

app.listen(3000, () => {
  const cache = new CachePugTemplates({ app, views });
  cache.start();
});

Options

• app (Object) - an instance of Koa, Express, or Connect
• views (String or Array) - a file directory path (or an Array of file directory paths) (if you pass an Express app instance as the app option, this will be automatically populated to your applications views configuration option via app.get('views'))
• logger (Object) - a logger, defaults to console (we recommend using Cabin for your logger)
• callback (Function) - defaults to false (no operation), but if a function is provided then it will be invoked with two arguments, file (String) and template (Function)
• cache (Boolean) - defaults to true, whether or not to cache templates automatically if cache.start() is called (useful if you are writing tests or have a custom approach using callback function)
• concurrency (Number) - number of concurrent files that can be cached per interval in parallel (defaults to 1)
• interval (Number) - duration of time in (milliseconds) to limit concurrency for (e.g. 1 cached file every 1000ms is the default), this value's default is 1000

Debugging

If you want to check what the cache state is at anytime:

const pug = require('pug');

// ...

// get everything:
console.log('pug.cache', pug.cache);

// just get the file names:
console.log('pug cached files', Object.keys(pug.cache));
