什么是merco,Merging, compressing and cache busting for js

merco使用教程帮助文档

Build Status

Merco is Express middleware for merging and minifying JS files in run time. It also support cache busting.

How to use it ?

install merco module:

  • npm install merco

use merco as middleware:

  • app.use(merco.init(params));

set route from which you want to serve files:

  • app.get('/build/*', merco.route);

use it in template (.ejs):

<% getJS('PATH/TO/FILE1') %>
<% getJS('PATH/TO/FILE2') %>

<%- printJS() %>

Params

route - route from which you want to serve files

version - cache buster, good practice is to use package.version

filePath - location of raw js files

buildPath - location where processed files should be stored (need write permissions on that folder)

sKey - secret key that will be used for encryption

cache - default true, in dev environment set cache to false

ignoreSameFile - default true, ignores same file while registering with getJS()

async - default false, includes async attribute to script tag. More about it here

Testing

npm run test

Why run time ?

  • in case of large application and big number of files doing this in run time is much more convinient
  • this is also useful in case of multivariant tests when we want to have different js for different variants
  • it’s easier to use in some case

Notes

For better performance use caching on nginx or akamai.
