@cross - Cross-Runtime JavaScript Libraries

Filling the gaps of @std/ on jsr.io - https://jsr.io/@cross

We develop essential cross-runtime libraries for Deno, Bun, and Node.js, extending the foundation of @std on JSR.io. Our libraries are designed for seamless cross-platform development, offering intuitive APIs and clear documentation.

• @cross/fs: Complete cross-runtime utility library offering functions for file system operations, such as diskusage(), size(), readFile(), stat(), mktempdir().
• @cross/utils: A toolbox of helpful cross-runtime utility functions like exit(), spawn(), args, ArgumentParser and more.
• @cross/env: Simple and consistent environment variable management across runtimes.
• @cross/runtime: Easily detect the current JavaScript runtime (Deno, Bun, Node.js, or browser), along with version, OS and more.
• @cross/test: Write cross-runtime tests utilizing the build in test runners of Deno, Node and Bun. Works great with @std/assert and Sinon.
• @cross/deepmerge: Deeply merge objects with flexibility and customizability across JavaScript environments.
• @cross/base64: Efficient cross-runtime base64/base64url validation.
• @cross/log: Flexible cross-runtime logging with customizable console styling, file output, log levels, and pluggable transports.
• @cross/service: Cross-runtime service installer library for Systemd, Upstart, Sysvinit usable in Node, Deno and Bun.
• @cross/dir: Cross-platform mechanism for retrieving the paths to standard user directories in Deno, Bun and Node.js
• @cross/jwt: A versatile JSON Web Token (JWT) library.
• @cross/kv: A fast, file based Key/Value Database with in-memory index for Node, Deno and Bun.
• @cross/workers: Cross-runtime worker pool with TypeScript support

We have also...

... created a set of common reusable and configurable GitHub workflows to streamline cross-runtime compatibility testing with Deno, Node, and Bun. Find them at github.com/cross-org/workflows.

Quick Examples

@cross/env

import { getEnv } from "@cross/env";

const port = getEnv("PORT") || "3000";
console.log(`Server listening on port ${port}`);

@cross/log

import { Log } from "@cross/log";

const logger = new Log();

log.log("This is a log");
log.warn("This is a warning");
log.debug("This is not shown by default");

@cross/runtime

import { CurrentRuntime } from "@cross/runtime";

if (CurrentRuntime === "deno") {
  console.log("You're running Deno!");
}

@cross/utils

import { args, Colors } from "@cross/utils";

console.log(Colors.bgGreen(Colors.bold("Success!")))

const commandLineArgs = args();
console.log(commandLineArgs);
