## プロジェクトの歴史と使われ方

JSON5 is both a data-format proposal and a JavaScript reference implementation for a more hand-editable superset of JSON. The format adds familiar ECMAScript 5.1 syntax such as comments, trailing commas, single-quoted strings, unquoted object keys, and additional number forms.

### プロジェクトの歴史

The JSON5 GitHub repository and npm package both date to May 2012. The official site describes JSON5 as `JSON for Humans`, positioning it for configuration and other hand-authored files rather than machine-to-machine interchange.

In March 2018, the JSON5 specification was published as Standard JSON5 1.0.0. The spec frames JSON5 as a superset of JSON that expands syntax with selected ECMAScript 5.1 productions while keeping JSON's data model.

### 採用の歴史

The official site reported in 2022 that JSON5 received more than 65 million npm downloads per week, ranked in the top 0.1 percent of depended-upon npm packages, and had been adopted by projects including Chromium, Next.js, Babel, Retool, WebStorm, and Apple platforms.

Its wide adoption came less from command-line use than from dependency graphs: parsers, build tools, configuration loaders, and editors pulled JSON5 in as a friendlier format for files people edit by hand.

### 使われ方

The JavaScript package exposes an API compatible with the standard JSON API, including `JSON5.parse()` and `JSON5.stringify()`, and the Homebrew formula provides the `json5` CLI. Typical usage is parsing configuration-like input that wants comments and trailing commas while preserving JSON-like data structures.

### パッケージ好きにとっての重要性

JSON5 is package-nerd significant because it became one of the few JSON-adjacent formats that escaped niche status. It is a reminder that tiny syntax conveniences in configuration files can create enormous dependency footprints once build systems and editors standardize around them.

### タイムライン

- 2012-05-27: The GitHub repository was created and npm recorded version 0.0.0.
- 2018-03: Standard JSON5 1.0.0 was published.
- 2021-02-01: GitHub recorded release v2.2.0.
- 2022: The official site reported more than 65 million npm downloads per week and major-project adoption.
- 2022-12-31: GitHub recorded release v2.2.3.

### Related projects

- JSON5 sits beside JSON, YAML, TOML, HJSON, and JSONC as a configuration-oriented data format. Its reference implementation is also related to non-JavaScript ports listed by the JSON5 organization.
