Easily read/write JSON files in Deno
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");Writes an object to a JSON file.
- 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 });
