The code to resolve the dependencies:
var DepWalker = ;// use main.js as entry point,// 2 source directories,// and 'depends' as the dependency statement.var walker =main: 'main.js'directories: 'src' 'lib'statement: 'depends';// return the sorted dependencies of main.js:// lib/B.js, lib/A.js, src/main.jsconsole;
Dependency with an entry point
lib/C.js is not in the list. It is because from the entry point
main.js, the dependency graph of
B.js, does not contains
This is useful when you building a final application, non-related files are removed to save space.
Dependency without an entry point
If NO entry point is supplied,
lib/C.js will be included in the sorted list. Since it will retrieve and sort all the files in
lib. The isolated files will be also included.
This is typically useful when building a library. So every files in the library could be used by other application.
The directories to be searched for.
A pattern matching string, using glob. Default to:
The entry point for calculating dependency graph. Differences between with and without supplying entry point is listed above.
The dependency statement. By default is
require. Dependency walker will extract this statement and its parameters in order to find out the file's dependencies.
