An easy-to-use library to resolve dependencies in a dependency tree
npm install dependency-tree-resolver
npm i dependency-tree-resolver --save-dev
and then
javascript
var DepResolver = require('dependency-tree-resolver');
`$3
Get a local copy of dep-res.js, or consume it via RawGit's CDN,
and add to your HTML:
html
`
and then you'll have DepResolver` on the `window` scope.API
Once you include the script in your project you'll have a function `DepResolver` which accepts two arguments:
`javascript
DepResolver(
tree = {
string: [...string],
...
},
options = {
exclude: [...string]
}
)
`
Arguments
* tree`: each key in the map represents a node in the tree, and each value in the array represents a single dependency of that node.
* `options`:
* `exclude`: allows you to specify which dependencies are special and allowed to not have a node for themselves (usefull when depending on external resources)Examples
`javascript
//valid tree
var tree = {a: [], b: ['c', 'd'], c: ['d'], d: ['a']};
var resolved = DepResolver(tree);
console.log(resolved);//['a','d','c','b' ]//invalid tree w/ excluded external resource
var tree = {a: ['b'], b: ['d']};
var options = {exclude: ['d']};
var resolved = DepResolver(tree, options);
console.log(resolved);//['b','a']
//invalid tree w/o excluded external resource
var tree = {a: ['b'], b: ['d']};
var resolved = DepResolver(tree);//throw error: "b" has an unknown dependency "d"
//invalid tree with cyclic dependency
var tree = {a: ['b'], b: ['c'], c: ['a'], d: ['e'], e: ['d']};
var resolved = DepResolver(tree);//throw error: circular dependency found: a > b > c > a
