🔎 literal-parser

A small library to parse and serialize JavaScript array/object literal.

This is like a JSON.parse / JSON.serialize but for JavaScript object instead of JSON objects.

Gist

import Parser from '@dldc/literal-parser';

Parser.parse('{ some: ["object", { literal: true }] }');
// return an object { some: ["object", { literal: true }] }

API

`Parser.parse(str)`

Parse the string, expect the string to contain only one expression and throw otherwise.

Return the parsed object.

`Parser.parseOne(str)`

Parse one expression then stop.

Returns a object with { value, length } where value is the parsed expression and length is the number of character parsed.

Parser.parseOne('{ props: true }} something="else" />');
// { value: { props: true }, length: 15 }

`Serializer.serialize(obj, format?)`

Print an object.

format is optional and can be one of the following:

`{ mode: 'line' } | 'line'`

Print on a single line with spaces. This is the default format

`{ mode: 'compact' } | 'compact'`

Print on a single line without any spaces.

`{ mode: 'indent' } | 'indent' | number`

Similar to JSON.stringify(obj, null, indent).

Options:

space (default: 2)

`{ mode: 'pretty' } | 'pretty'`

Inspired by prettier, this mode will try to print objects and arrays on a single line, if the result is bigger than the threshold then it's splitted into multiple lines.
