objtree
is a script that generates a text tree representation of an object. The script can be executed in a browser console or imported as an npm
module.
How to Use
var target = {};
var result = objtree(target, {
// Maximum level of recursion
maxlevel: 10,
// Prefixed before every name (ex. window)
grandparent: "",
// String used to indent lines to display the level of nesting
indentstr: " ",
// Array of strings (behaving like regular expressions) matched against names to exclude
// Use / to separate nested objects (ex. {a:{b:{c:true}}} will be a/b/c)
// Note that grandparent is not included in the name matching process
exclude: []
});
result.asObj(); // returns internal representation of the tree
result.asText(); // returns a formatted text representation
result.downloadText(filename); // triggers a browser file download with the formatted text
Example
var target = {
testBool: true,
testInt: 15,
testFloat: -3.6,
testString: "text",
testFunction: function(a, b, c){},
testArray1: [ 1, 2, true, "abc" ],
testArray2: [
{ hi: "there" },
[ 0, 1, [false] ]
],
testObject: {
abc: [ 1, 2 ]
}
};
target.testObject["testSpecial-Name!"] = null;
function MyClass(){}
MyClass.CONSTANT = true;
MyClass.data = 10;
MyClass.prototype.a = function(){};
MyClass.prototype.b = function(){};
target["testClass"] = MyClass;
Calling objtree(target).asText()
with no additional settings yields (ordered by type and then name):
