List all possible paths using lodash

Question

I would like to list all paths of object that lead to leafs

Example:

var obj = {
 a:\"1\",
 b:{
  foo:\"2\",
  bar:3
 },
 c:[0,1]
}

Answer 1

Here is my function. It generates all possible paths with dot notation, assuming there are no property names containing spaces

function getAllPathes(dataObj) {
    const reducer = (aggregator, val, key) => {
        let paths = [key];
        if(_.isObject(val)) {
            paths = _.reduce(val, reducer, []);
            paths = _.map(paths, path => key + '.' + path);
        }
        aggregator.push(...paths);
        return aggregator;
    };
    const arrayIndexRegEx = /\.(\d+)/gi;
    let paths = _.reduce(dataObj, reducer, []);
    paths = _.map(paths, path => path.replace(arrayIndexRegEx, '[$1]'));

    return paths;
}
