A simple JSON parser that supports comments and optional trailing commas.
npm install jsonc-simple-parserA simple JSON parser that supports comments and optional trailing commas.
- Tiny:
- It's ~3.5kb minified and gzipped, if you aren't already using RegHex, otherwise it's just ~2kb.
- Even if you aren't using RegHex already (you should) that's ~32% smaller than VS Code's jsonc-parser and ~62% smaller than JSON5.
- Performant:
- When parsing regular JSON it's ~10x faster than VS Code's jsonc-parser, ~70x faster than JSON5 and just as fast as the native JSON.parse.
- When parsing JSON with comments or trailing commas it's just as fast as VS Code's jsonc-parser and ~6x faster than JSON5.
- Tested:
- It passes all 274 tests regarding JSON from ECMA's test262 test suite.
- The parser is obviously not spec compliant but this means that while adding support for comments and trailing commas probably nothing else got broken.
``sh`
npm install --save jsonc-simple-parser
`ts
import JSONC from 'jsonc-simple-parser';
const source =
{ // This is an example
"foo": 123,
/ TRAILING COMMAS /
"bar": [1, 2, 3,],
};
const result = {
foo: 123,
bar: [1, 2, 3]
};
JSONC.parse ( source ); // => returns an object that's deeply equal to result
JSONC.stringify ( result ); // => same as calling
