pocket-console

Santa Claus came early this year and gifted this sleak little logging lib written in TypeScript.

It is a drop-in replacement of console.

It got colors, log levels, automatic grouping, and yes also some of those unicode chars if you like.

0, zero, nada, zip, none, no dependencies.

Also, controllable via env variables.

Colors are automatically turned off when not outputting to a terminal.

// options are optional.
const options = {module: "ModuleName", level: "error" | "warn" | "info" | "debug", format: "%c%M%t %m %l"};

let console = PocketConsole(options);

// aced has same loglevel threshold as info.
console.aced("Oh yeah!");

console.error("Oh, snap!");

console.warn("Hey, hold on!");

console.info("Heads up!");

console.debug("FYI");

console.getConsole().error("Use the original console object to output directly to stderr");

console.log("stdout logging is not formatted in any way");

// Grouped output (secondary lines are indented).
console.aced("BTW: here is the result", {name: "Bobby", callSign: "0xdeadbeef"});

// Console's other functionality is still available.
console.table([{col1: "table", col2: "still works"}], ["col1", "col2"]);

An important feature is that options can ge globally set using env variables. So if multiple dependencies of your project is using pocket-console then you can steer the loglevel and logformat for all those loggers, like:

node -r ts-node/register ./example/example-one.ts

LOG_FORMAT="%c%L" node -r ts-node/register ./example/example-one.ts

LOG_LEVEL=none node -r ts-node/register ./example/example-one.ts

It does automatic grouping for you, if you have more than one argument or the single argument is non-string.
