doowb/stringify-keys: Build an array of key paths from an object.

Build an array of key paths from an object.

Please consider following this project's author, Brian Woodward, and consider starring the project to show your ❤️ and support.

Install with npm:

$ npm install --save stringify-keys

See the Release History for changes.

const stringify = require('stringify-keys');

let obj = { a: 'a', b: { c: { d: { e: 'f' } } } };
console.log(stringify(obj));
//=> [ 'a', 'b.c.d.e' ]

Include values in the result:

console.log(stringify(obj, { values: true }));
//=> { a: 'a', 'b.c.d.e': 'f' }

Keys with dots are automatically escaped with backslashes (this can be customized):

let obj = { 'a.b.c': { d: 'e' } };
console.log(stringify(obj));
//=> [ 'a\\.b\\.c.d' ]

console.log(stringify(obj, { values: true }));
//=> { 'a\\.b\\.c.d': 'e' }

Objects with arrays return the array indices as part of the paths:

let obj = { a: 'a', b: [{ c: { d: 'e' } }, { f: { g: 'h' } }] };

console.log(stringify(obj));
//=> [ 'a', 'b.0.c.d', 'b.1.f.g' ]

console.log(stringify(obj, { values: true }));
//=> { a: 'a', 'b.0.c.d': 'e', 'b.1.f.g': 'h' }

Type: string

Default: .

Custom separator to use for creating object paths (a.b.c):

Example

let obj = { 'a.b.c': { d: 'e' } };
console.log(stringify(obj, { separator: '/' }));
//=>  [ 'a.b.c/d' ]

console.log(stringify(obj, { separator: '/', values: true }));
//=>  { 'a.b.c/d': 'e' }

Type: function

Default: adds \\ before dots

Custom function to use for escaping keys.

Example

let obj = { 'a.b.c': { d: 'e' } };
let escape = str => str.split('.').join('/');

console.log(stringify(obj, { escape }));
//=>  [ 'a/b/c.d' ]

console.log(stringify(obj, { escape, values: true }));
//=>  { 'a/b/c.d': 'e' }

Redundant (parent) keys are no longer included in the output. Thus { a: { b: 'c' } } now returns ['a.b'] instead of ['a', 'a.b'].

Added support for traversing into arrays.
