🔎 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 }] }
Supported features
Take a look at the tests see what is supported.
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.
Options:
space
(default:2
)threshold
(default:80
)
