Serialize objects to JSON with handling for circular references
JSON.stringify() throws an error if the object contains circular references. This package replaces circular references with "[Circular]".
npm install safe-stringify
import safeStringify from 'safe-stringify';
const foo = {a: true};
foo.b = foo;
console.log(safeStringify(foo));
//=> '{"a":true,"b":"[Circular]"}'
console.log(JSON.stringify(foo));
//=> TypeError: Converting circular structure to JSON
Returns a string.
Note: There is no replacer option as I didn't need that, but “pull request welcome” if you need it.
Type: unknown
The value to convert to a JSON string.
Type: object
Type: 'string' | 'number'
The indentation of the JSON.
By default, the JSON is not indented. Set it to '\t' for tab indentation or the number of spaces you want.
The existing ones either did too much, did it incorrectly, or used inefficient code (not using WeakSet). For example, many packages incorrectly replaced all duplicate objects, not just circular references, and did not handle circular arrays.
