import { Deno } from "https://deno.land/x/adka_server@0.1.5/deno.d.ts";
const { inspect } = Deno;
Converts the input into a string that has the same format as printed by
console.log()
.
const obj = {};
obj.propA = 10;
obj.propB = "hello";
const objAsString = Deno.inspect(obj); // { propA: 10, propB: "hello" }
console.log(obj); // prints same value as objAsString, e.g. { propA: 10, propB: "hello" }
You can also register custom inspect functions, via the customInspect
Deno
symbol on objects, to control and customize the output.
class A {
x = 10;
y = "hello";
[Deno.customInspect](): string {
return "x=" + this.x + ", y=" + this.y;
}
}
const inStringFormat = Deno.inspect(new A()); // "x=10, y=hello"
console.log(inStringFormat); // prints "x=10, y=hello"
Finally, a number of output options are also available.
const out = Deno.inspect(obj, {showHidden: true, depth: 4, colors: true, indentLevel: 2});
