console-craft

(english/简体中文)

Simplify console program development, standardize program parameters and log output, and provide support for user interaction or command-line parameters to start the main program and subcommands.。

Use Cases

• Support multiple subcommands.

• Global parameters and subcommand parameters.

• Program parameters can be obtained from environment variables and the command line.

• Built-in dotenv handling, program parameters can also be obtained from dotenv.

• Parameter source priority: interactive input > command-line parameters > environment variables > dotenv.

• You can select subcommands and parameters through user interaction.

• You can directly launch subcommands through command-line parameters.

• It includes the log4js library, and you can set the log format through parameters.

• It includes Commander, Inquirer, and Chalk for enriching program interaction and appearance.

Example

• project example，GitHub - topabomb/console-craft-example

  The program includes two subcommands: 'serve' which starts an HTTP server, and 'test' which directly invokes local testing with Mocha.

import { execa } from "execa";
import { cli } from "console-craft";
import { service } from "./serve";
const commands = [
  { name: "serve", args: [{ flags: "-p, --port <port>", default: 3000 }] },
  { name: "test", args: ["-r, --round <round>"] },
];
cli.initialize(commands, {
  globalArgs: [
    { flags: "-c, --config <config>", description: "config file" },
    "-log,  --log-level",
  ],
  author: "topabomb([email protected])",
  description: "node console app.",
});
cli.command("serve", async ({ name, args, logger }) => {
  const port = Number(args["port"]);
  await service.start(port);
  logger.level = args["log-level"] ? args["log-level"] : "debug";
  logger.info(`${name} listening : http://localhost:${args["port"]}`);
});
cli.command("test", async ({ name, args, logger }) => {
  await service.start(3000);
  const round = args["round"] ? Number(args["round"]) : 1;
  for (let i = 0; i < round; i++)
    await execa("npm", ["run", "test"]).pipeStdout(process.stdout);
  await service.close();
  logger.log("test complete.");
});
void cli.run();
