automatically detect the protocol, use the new inspector when the targeted runtime >=7.0.0 .

if running without VSCode or WebStorm, we will use inspector-proxy to proxy worker debug, so you don't need to worry about reload.

$ egg-bin debug --debug-port=9229 --proxy=9999

options

• files is optional, default to test/**/*.test.js
• test/fixtures, test/node_modules is always exclude.

auto require test/.setup.js

If test/.setup.js file exists, it will be auto require as the first test file.

test
  ├── .setup.js
  └── foo.test.js

options

You can pass any mocha argv.

• --require require the given module
• --grep only run tests matching
• --timeout milliseconds, default to 60000
• --full-trace display the full stack trace, default to false.
• --typescript / --ts enable typescript support, default to false.
• --changed / -c only test changed test files(test files means files that match ${pwd}/test/**/*.test.(js|ts))

• see more at https://mochajs.org/#usage

environment

Environment is also support, will use it if options not provide.

You can set TESTS env to set the tests directory, it support glob grammar.

TESTS=test/a.test.js egg-bin test

And the reporter can set by the TEST_REPORTER env, default is spec.

TEST_REPORTER=doc egg-bin test

The test timeout can set by TEST_TIMEOUT env, default is 60000 ms.

TEST_TIMEOUT=2000 egg-bin test

cov

Using [nyc] to run code coverage, it support all test params above.

Coverage reporter will output text-summary, json and lcov.

options

You can pass any mocha argv.

• -x add dir ignore coverage, support multiple argv

• --prerequire prerequire files for coverage instrument, you can use this options if load files slowly when call mm.app or mm.cluster

• --typescript / --ts enable typescript support, default to false, if true, will auto add .ts extension and ignore typings and d.ts.

• --nyc nyc instruments passthrough. you can use this to overwrite egg-bin's default nyc instruments and add additional ones.

  if you want to add addtional nyc reporters, you need to use this rather than add reporter key in .nycrc because:

  • when same key exists in .nycrc and cmd instruments, nyc prefers instrument.
  • egg-bin have some default instruments passed to nyc like -r and --temp-directory
  • egg-bin cov --nyc="-r teamcity -r text"

• also support all test params above.

environment

You can set COV_EXCLUDES env to add dir ignore coverage.

$ COV_EXCLUDES="app/plugins/c*,app/autocreate/**" egg-bin cov

pkgfiles

Generate pkg.files automatically before npm publish, see ypkgfiles for detail

$ egg-bin pkgfiles

autod

Generate pkg.dependencies and pkg.devDependencies automatically, see autod for detail

$ egg-bin autod

Custom egg-bin for your team

You maybe need a custom egg-bin to implement more custom features if your team has develop a framework base on egg.

Now you can implement a Command sub class to do that. Or you can just override the exists command.

See more at common-bin.

Example: Add nsp for security scan

nsp has provide a useful security scan feature.

This example will show you how to add a new NspCommand to create a new egg-bin tool.

• Full demo: my-egg-bin

my-egg-bin

const EggBinCommand = require('egg-bin');

class MyEggBinCommand extends EggBinCommand {
  constructor(rawArgv) {
    super(rawArgv);
    this.usage = 'Usage: egg-bin [command] [options]';

    // load directory
    this.load(path.join(__dirname, 'lib/cmd'));
  }
}

module.exports = MyEggBinCommand;

NspCommand

const Command = require('egg-bin').Command;

class NspCommand extends Command {
  * run({ cwd, argv }) {
    console.log('run nsp check at %s with %j', cwd, argv);
  }

  description() {
    return 'nsp check';
  }
}

module.exports = NspCommand;

my-egg-bin.js

#!/usr/bin/env node

'use strict';
const Command = require('..');
new Command().start();

Run result

$ my-egg-bin nsp

run nsp check at /foo/bar with {}
