This differs from the other plugins: + +- `eslint-plugin-json` uses a processor to parse the JSON, meaning it doesn't create an AST and you can't write custom rules for it. +- `eslint-plugin-jsonc` uses a parser that still goes through the JavaScript linting functionality and requires several rules to disallow valid JavaScript syntax that is invalid in JSON. + +As such, this plugin is more robust and faster than the others. You can write your own custom rules when using the languages in this plugin, too. + +### What about missing rules that are available in `eslint-plugin-json` and `eslint-plugin-jsonc`? + +Most of the rules in `eslint-plugin-json` are actually syntax errors that are caught automatically by the parser used in this plugin. + +Similarly, many of the rules in `eslint-plugin-jsonc` specifically disallow valid JavaScript syntax that is invalid in the context of JSON. These are also automatically caught by the parser in this plugin. + +Any other rules that catch potential problems in JSON are welcome to be implemented. You can [open an issue](https://github.com/eslint/json/issues/new/choose) to propose a new rule. + ## License Apache 2.0 + +## Sponsors + + + + + + +
