jsonthrow
A small utility for JSON (parse and stringify) that follows error first approach inspired from rust.
Installation
npm install jsonthrow
usage
Example in a .ts file
// example.ts file
import { jsonthrow } from "jsonthrow";
const data = {
msg: "hello word",
};
function test() {
const [result, error] = jsonthrow.stringify(data);
// at this point result is either null or string
if (error) {
// do something
return;
}
// since we checked for error result is string at this point
console.log(result);
const [result2, error2] = jsonthrow.parse<typeof data>(result);
if (error2) {
// do something
return;
}
console.log(result2); // will be of type data
}Example in a .js file
// example.js file
const { jsonthrow } = require("jsonthrow");
const data = {
msg: "hello word",
};
function test() {
const [result, error] = jsonthrow.stringify(data);
// at this point result is either null or string
if (error) {
// do something
return;
}
// since we checked for error result is string at this point
console.log(result);
const [result2, error2] = jsonthrow.parse(result);
if (error2) {
// do something
return;
}
console.log(result2);
