  • it assigns on exports changeable to export one public interface

Not anymore: dependencies need to be clearly announced, and finding an item of rule only means looking at the document path inside need declaration

Is not that inside the global scope? No, there’s absolutely no worldwide scope here. Each module has its own range. This will be like having each component implicitly wrapped in a anonymous features (which means that variables explained are local toward module).

OK, think about requiring jQuery or other collection? Discover basically two how to need a file: either by specifying a file course (like ./lib/model.js ) or by demanding it by name: var $ = require(‘jquery’); . Items required by file route are situated immediately by their own identity within the file program. Points necessary for name were “packages” and tend to be explored from the need mechanism. In the example of Node, it uses an easy directory look; inside web browser, really, we can establish bindings because you will read after.

Actually this exactly the same thing as only covering everything in a closing, that you might already do? No, not by a long try.

It generally does not unintentionally alter international condition, plus it best exports one thing. Each CommonJS module executes with its own delivery context. Factors tend to be local towards the component, maybe not global. You’ll best export one object per module.

Dependencies are really easy to discover, without being modifiable or accessible in the worldwide range. Actually come confused about where some work is inspired by, or exactly what the dependencies of a certain bit of laws is? There aren’t any implied worldwide factors.

But isn’t proclaiming dependencies redundant and not DRY? Yes, it is not as easy as utilizing worldwide variables implicitly by making reference to variables explained under screen . Continue reading
