I have a javascript plain object like this one: {a: {b: 1} }
and I want to convert it to a dot-notation string like this a.b = 1
use case:
sending the object to a plain-text environment such as cli or as a url parameter.
It's rather hard to tell whether this is what you want, but something like this would flatten a tree of objects into a list of dotted paths...
var data = {
a: {
b: 1,
c: {
d: 8
}
},
e: {
f: {
g: 9
},
h: 10,
i: [1, 2, 3]
}
};
function toDotList(obj) {
function walk(into, obj, prefix = []) {
Object.entries(obj).forEach(([key, val]) => {
if (typeof val === "object" && !Array.isArray(val)) walk(into, val, [...prefix, key]);
else into[[...prefix, key].join(".")] = val;
});
}
const out = {};
walk(out, obj);
return out;
}
console.log(toDotList(data));
