The JSON5 Data Interchange Format (JSON5) is a superset of \href{https://tools.ietf.org/html/rfc7159}{\texttt{ JSON}} that aims to alleviate some of the limitations of JSON by expanding its syntax to include some productions from \href{https://www.ecma-international.org/ecma-262/5.1/}{\texttt{ ECMAScript 5.\+1}}.

This Java\+Script library is the official reference implementation for JSON5 parsing and serialization libraries.\hypertarget{md_sfcode_node_modules_mini_css_extract_plugin_node_modules_json5_README_autotoc_md17461}{}\doxysection{Summary of Features}\label{md_sfcode_node_modules_mini_css_extract_plugin_node_modules_json5_README_autotoc_md17461}

\begin{DoxyItemize}
\item {\ttfamily value}\+: The value to convert to a JSON5 string.
\item {\ttfamily replacer}\+: A function that alters the behavior of the stringification process, or an array of String and Number objects that serve as a whitelist for selecting/filtering the properties of the value object to be included in the JSON5 string. If this value is null or not provided, all properties of the object are included in the resulting JSON5 string.
\item {\ttfamily space}\+: A String or Number object that\textquotesingle{}s used to insert white space into the output JSON5 string for readability purposes. If this is a Number, it indicates the number of space characters to use as white space; this number is capped at 10 (if it is greater, the value is just 10). Values less than 1 indicate that no space should be used. If this is a String, the string (or the first 10 characters of the string, if it\textquotesingle{}s longer than that) is used as white space. If this parameter is not provided (or is null), no white space is used. If white space is used, trailing commas will be used in objects and arrays.
\item {\ttfamily options}\+: An object with the following properties\+:
\begin{DoxyItemize}
\item {\ttfamily replacer}\+: Same as the {\ttfamily replacer} parameter.
\item {\ttfamily space}\+: Same as the {\ttfamily space} parameter.
\item {\ttfamily quote}\+: A String representing the quote character to use when serializing strings.

Then you can load a JSON5 file with a Node.\+js {\ttfamily require()} statement. For example\+:

\href{https://github.com/aseemk}{\texttt{ Assem Kishore}} founded this project.

\href{http://bolinfest.com/}{\texttt{ Michael Bolin}} independently arrived at and published some of these same ideas with awesome explanations and detail. Recommended reading\+: \href{http://bolinfest.com/essays/json.html}{\texttt{ Suggested Improvements to JSON}}

\href{http://www.crockford.com/}{\texttt{ Douglas Crockford}} of course designed and built JSON, but his state machine diagrams on the \href{http://json.org/}{\texttt{ JSON website}}, as cheesy as it may sound, gave us motivation and confidence that building a new parser to implement these ideas was within reach! The original implementation of JSON5 was also modeled directly off of Doug’s open-\/source \href{https://github.com/douglascrockford/JSON-js/blob/master/json_parse.js}{\texttt{ json\+\_\+parse.\+js}} parser. We’re grateful for that clean and well-\/documented code.

\href{https://github.com/MaxNanasy}{\texttt{ Max Nanasy}} has been an early and prolific supporter, contributing multiple patches and ideas.

\href{https://github.com/aeisenberg}{\texttt{ Andrew Eisenberg}} contributed the original {\ttfamily stringify} method.

\href{https://github.com/jordanbtucker}{\texttt{ Jordan Tucker}} has aligned JSON5 more closely with ES5, wrote the official JSON5 specification, completely rewrote the codebase from the ground up, and is actively maintaining this project.
