The format adds familiar ECMAScript 5.1 syntax such as comments, trailing commas, single-quoted strings, unquoted object keys, and additional number forms. ### Project history 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. ### Adoption history 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. ### How it is used 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. ### Why package nerds care 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. ### Timeline - 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. ### Sources - - - - - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** json5 - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Related links - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Text processing packages](https://www.automicvault.com/pkg/text-processing-tools/) - Matched text, document, or structured-data processing metadata. - [Developer build packages](https://www.automicvault.com/pkg/developer-build-tools/) - Matched build, compiler, generator, or developer workflow metadata. - [Networking and protocol packages](https://www.automicvault.com/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [node](https://www.automicvault.com/pkg/brew/node/) - Runtime dependency declared by Homebrew. - [hjson](https://www.automicvault.com/pkg/brew/hjson/) - Shares av.db curated category or tags: cli, configuration, data-format, developer-tools, json. - [xmq](https://www.automicvault.com/pkg/brew/xmq/) - Shares av.db curated category or tags: cli, data-format, developer-tools, json. - [yajl](https://www.automicvault.com/pkg/brew/yajl/) - Shares av.db curated category or tags: cli, data-format, developer-tools, json. - [config-file-validator](https://www.automicvault.com/pkg/brew/config-file-validator/) - Shares av.db curated category or tags: cli, configuration, developer-tools, json. - [dhall-json](https://www.automicvault.com/pkg/brew/dhall-json/) - Shares av.db curated category or tags: cli, configuration, developer-tools, json. - [dyff](https://www.automicvault.com/pkg/brew/dyff/) - Shares av.db curated category or tags: cli, configuration, developer-tools, json. - [go-jsonnet](https://www.automicvault.com/pkg/brew/go-jsonnet/) - Shares av.db curated category or tags: cli, configuration, developer-tools, json. - [jrsonnet](https://www.automicvault.com/pkg/brew/jrsonnet/) - Shares av.db curated category or tags: cli, configuration, developer-tools, json. - [json5](https://www.automicvault.com/pkg/npm/json5/) - Same normalized package name appears in another local ecosystem.
