json

JSON encode/decode.

Naming convention: import the module under its bare name (import "json"), reach members with a backslash, and call methods in camelCase: json\someMethod.

Methods

parse

Decode a JSON string into a value (map, list, string, number, or boolean).

Signature: json\parse(s) → any¹ · source

Returns: any

Example:

import "std";
import "json";

final v = json\parse("\{\"name\": \"api\", \"port\": 8080\}");
std\print(v["name"]);
std\print(v["port"]);
// -> api
// -> 8080

stringify

Encode a value as a JSON string. With no indent (or "") the output is compact; pass an indent string (e.g. " " or "\t") for pretty, multi-line output.

Signature: json\stringify(value, [indent]) → string² · source

Returns: string

Example:

import "std";
import "json";

final config = { "target": "build", "parallel": true };
std\print(json\stringify(config));
// -> {"parallel":true,"target":"build"}

// Pretty-printed with two-space indent:
std\print(json\stringify(config, "  "));
