Save Express responses to a static directory for disk caching
Use save-static as a callback on Express Application.render() or Response.render() and it will:
- Write the rendered response body (HTML) to a file on disk
- after sending the response to the client (to avoid slow responses)
Then subsequent requests can be served from disk using:
Use in conjunction with serve-static-x for caching and re-caching files to disk.
$ npm install --save save-static// be sure to require it
var SaveStatic = require('save-static');
// initialize with the root path for saving to disk
var staticPath = __dirname + '/static'; // <= for example
var saveStatic = new SaveStatic(staticPath);
// ...
// here's a sample Express route
app.get('/nfl/afc/east/teams', function(req, res, next) {
res.render('division', {
teams: ['Patriots', 'Jets', 'Bills', 'Dolphins']
}, saveStatic(res)); // <= easy as that
// the render HTML will be saved to a file on disk at:
// staticPath + /nfl/afc/east/teams.html
// NOTE: you can pass a callback too, e.g. saveStatic(res, next)
// however, if there is no error, the response will have already
// been sent to the client.
// NOTE: a route for "/" will be saved on disk as 'index.html'
// NOTE: a route for "/something.xhtml" will be saved
// on disk as 'something.xhtml'
