Emoji based semantic debuging
- Debug the state and execution flow of your program using familiar idioms
- Scoped debuging: activate emo locally
- Hooks: callback to execute after logging
npm install emosd
or
yarn add emosd
import Emo from "./emosd";
const emo = new Emo();
const zone2 = new Emo({ zone: "zone2" });
const zone3 = new Emo({ zone: "zone3", hook: (v) => { console.log("Zone 3 hook for", v) } });
async function run() {
emo.section("Run");
emo.state("A state operation");
emo.save("Saving something", { foo: "bar" });
emo.delete("Deleting something");
emo.update("Updating something");
emo.ok("Everything is ok");
zone2.start("Start");
zone2.transmit({ foo: "bar" });
zone2.notFound("Something not found");
zone3.warning("a warning");
Console output:
The recommended way is to use local Emo
instances to be able to enable and disable debug messages for a defined portion of code. Use the zone
attribute to prefix the messages:
const emo = new Emo({ zone: "api" });
// the messages will be prefixed by [api] :
emo.notFound(`page not found: ${path}`);
// output:
// 🚫 [api] Page not found: /some_page.html
It is possible to deactivate the printing of the messages for an instance:
const emo = new Emo({ deactivatePrint: true });
Callbacks to execute after logging. Ex:
const emo = new Emo({
hook: (msg) => { console.log(`Hook with message ${msg}`); }
});
const data = { foo: "bar" };
emo.json(data);
// or
Emo.json(data);
