Easily read/write JSON files in Deno

readJson

Reads a JSON file and then parses it into an object

import { readJson, readJsonSync } from "https://deno.land/x/jsonfile/mod.ts";

const f = await readJson("./foo.json");
const foo = readJsonSync("./foo.json");

writeJson

Writes an object to a JSON file.

WriteJsonOptions

• replacer : An array of strings and numbers that acts as a approved list for selecting the object properties that will be stringified.
• space : Adds indentation, white space, and line break characters to the return-value JSON text to make it easier to read.

You can also specify options from Deno.WriteFileOptions to configure how the file is written.

import { writeJson, writeJsonSync } from "https://deno.land/x/jsonfile/mod.ts";

writeJson("./target.json", { foo: "bar" }, { spaces: 2 }); // returns a promise
writeJsonSync("./target.json", { foo: "bar" }, { replacer: ["foo"] }); // void

// appends to the file instead of rewriting
writeJsonSync("./target.json", { foo: "bar" }, { append: true });
