Parsing and serializing TOML
TOML is a widely used configuration language designed to be feature-rich and intuitive to write.
import { parse, stringify } from "jsr:@std/toml";
To parse a TOML string, you can use the the standard library's TOML parse function. The value is returned as a JavaScript object.
const text = `
int = 1_000_000
bool = true
[[bin]]
name = "deno"
path = "cli/main.rs"
[[bin]]
name = "deno_core"
path = "src/foo.rs"
`;
const data = parse(text);
console.log(data.int);
console.log(data.bin.length);
To turn a JavaScript object into a TOML string, you can use the standard library's TOML stringify function.
const obj = {
ping: "pong",
complex: [
{ name: "bob", age: 10 },
{ name: "alice", age: 12 },
],
};
const toml = stringify(obj);
console.log(toml);
// ping = "pong"
//
// [[complex]]
// name = "bob"
// age = 10
//
// [[complex]]
// name = "alice"
// age = 12
