The Growing Risk of Malicious Browser Extensions
Socket researchers uncover how browser extensions in trusted stores are used to hijack sessions, redirect traffic, and manipulate user behavior.
A node module for creating tree data structure from text input
This module takes a simplified tree structured input string and build a JavaScript tree object in memory.
A simple tree structured input string (input.txt) example:
#root node
##node1
###node11
##node2
It illustrates a tree as below:
root node
|-- node1
| |--node11
|-- node2
Each line represents a node in the tree, it should begins with the leading character (default is #). The count of leading chracters minus 1 is the level of the node. There should be only 1 root node which has only 1 leading character, and it should be at the first line of the input string.
var freetree = require('freetree');
var tree = freetree.parse(str, settings);
settings
has below listed properties
leadingChar
: optional, defines leading character for the tree, defaulted to '#'compact
: optional, output the object in compact mode.Prepare an input.txt
file as above demonstrated.
var fs = require('fs');
var freetree = require('freetree');
var str = fs.readFileSync('input.txt', 'utf8');
var tree = freetree.parse(str);
then, the tree
object is an in-memory JavaScript object. In this example, the object is in structure:
{
"level": 0,
"value": "root",
"nodes": [{
"level": 1,
"value": "node1",
"nodes": [{
"level": 2,
"value": "node11"
}]
}, {
"level": 1,
"value": "node2"
}]
}
If the compact
option is set to true
, the object will be compressed in below structure:
{
"root": [{
"node1": [{
"node11": null
}]
}, {
"node2": null
}]
}

is installed globally
