JSON, JSONC and JSON5 parser for use with ESLint plugins
npm install jsonc-eslint-parser





[JSON], [JSONC] and [JSON5] parser for use with [ESLint] plugins.
This parser allows us to lint [JSON], [JSONC] and [JSON5] files.
This parser and the rules of [eslint-plugin-jsonc] would catch some of the mistakes and code style violations.
See [eslint-plugin-jsonc] for details.
``bash`
npm i --save-dev jsonc-eslint-parser
In your ESLint configuration file, set the parser property:
`js
import * as jsoncParser from "jsonc-eslint-parser";
export default [
{
// ...
// Add the following settings.
files: ["/.json", "/.json5"], // Specify the extension or pattern you want to parse as JSON.
languageOptions: {
parser: jsoncParser, // Set this parser.
}
},
];
`
In your ESLint configuration file, set the overrides > parser property:
`json5`
{
// ...
// Add the following settings.
"overrides": [
{
"files": [".json", ".json5"], // Specify the extension or pattern you want to parse as JSON.
"parser": "jsonc-eslint-parser", // Set this parser.
},
],
}
The following additional configuration options are available by specifying them in parserOptions in your ESLint configuration file.
`json5`
{
// Additional configuration options
"parserOptions": {
"jsonSyntax": "JSON5"
}
}
Set to "JSON", "JSONC" or "JSON5"`. Select the JSON syntax you are using.
If not specified, all syntaxes that express static values are accepted. For example, template literals without interpolation.
Note : Recommended to loosen the syntax checking by the parser and use check rules of [eslint-plugin-jsonc] to automatically fix it.
- AST.md is AST specification.
- Plugins.md describes using this in an ESLint plugin.
- no-template-literals.ts is an example.
- You can see the AST on the Online DEMO.
