Pros and Cons of `npm scripts` vs Gulp

Comparison of npm scripts vs Gulp

npm scripts

Pros

  • npm scripts are low-level and leverage the actual library you want to use (example: "lint": "eslint ./")
  • package.json is a central place to see what scripts are available (also npm run will list all scripts)
  • When things get too complicated you can always defer to another file (example: "complex-script": "babel-node tools/complex-script.js")
  • npm scripts are more powerful than one might first think (pre/post hooks, passing arguments, config variables, chaining, piping, etc...)

Handle CORS Client-side

Handle CORS Client-side

Cross-origin resource sharing (CORS) is a mechanism that allows restricted resources (e.g. fonts) on a web page to be requested from another domain outside the domain from which the first resource was served. This is set on the server-side and there is nothing you can do from the client-side to change that setting, that is up to the server/API. There are some ways to get around it tho.

Sources : MDN - HTTP Access Control | Wiki - CORS

CORS is set server-side by supplying each request with additional headers which allow requests to be requested outside of the own domain, for example to your localhost. This is primarily set by the header:

Access-Control-Allow-Origin
