Overview

A light weight set of handy tools for real world program.

Reduce the gap between different systems. Such as watch directory changes on a network file system, operate spawn on Windows and Linux, handle async IO api with promise, etc.

Rather than help you decide what to do, it is designed to create possibilities. Even this document is generated by nokit itself.

NPM version Build Status Build status Deps Up to Date

Features

  • All async functions will return promise.
  • All functions are highly lazy designed, minimum boot time.
  • Light weight and self-reference.

Installation

As a lib dependency, install it locally: npm i nokit.

  • Overview

    Nokit extends all the functions of nofs and yaku/lib/utils. You can use it as same as nofs. For more info, see the doc:

    Offline Documentation

    • example:

      kit.readFile('test.txt', 'utf8').then((str) =>
          console.log(str)
      );
      
      kit.outputFile('a.txt', 'test')
      .then(() => kit.log('done'));
      
      kit.writeJSON('b.json', { a: 10 })
      .then(() => kit.log('done'))
      
      kit.mkdirs('b.json', { a: 10 })
      .then(() => kit.log('done'));
  • _

    The lodash lib.

    • type: { Object }

    • example:

      kit._.map([1, 2, 3]);
  • browserHelper(opts)

    The browser helper. It helps you to live reload the page and log remotely.

    • static:

    • param: opts { Object }

      The options of the client, defaults:

      {
       host: '', // The host of the event source.
       useJs: false // By default the function will return html string
      }
    • return: { String }

      The code of client helper.

    • example:

      When the client code is loaded on the browser, you can use the nb.log to log anything to server's terminal. The server will auto-format and log the information to the terminal. It's convinient for mobile development when remote debug is not possible.

      // The nb is assigned to the "window" object.
      nb.log({ a: 10 });
      nb.log(10);
      nb.es.addEventListener('fileModified', () =>
       console.log('file changed')
      );
  • brush

    • example:

      let br = kit.require('brush');
      kit.log(br.red('error info'));
      
      // Disable color globally.

    The semantic versioner for npm, known as semver. You must kit.require 'semver' before using it.

    • type: { Object }
  • spawn(cmd, args, opts)

    A safer version of child_process.spawn to cross-platform run a process. In some conditions, it may be more convenient to use the kit.exec. It will automatically add node_modules/.bin to the PATH environment variable.

    • param: cmd { String }

      Path or name of an executable program.

    • param: args { Array }

      CLI arguments. If any of the item is an object, it will be converted to string by JSON.stringify.

       isSequential: false
      }
    • param: fn { Function }

      (val) -> Promise | Any The task function. If it is a async task, it should return a promise. It will get its dependency tasks' resolved values.

    • property: run { Function }

      Use it to start tasks. Each task will only run once. (names = 'default', opts) ->. The names can be a string or array. The default opts:

       // Will be passed as the first task's argument.
       init: undefined,
      
       // To stop the run currently in process. Set the `$stop`
       // reference to true. It will reject a "runStopped" error.
       warp: { $stop: false }
      }
    • property: list { Object }

      The defined task functions.

    • return: { Promise }

       baseDir: String
      }
    • return: { Object }

      {
       // The drive can also be a promise that will resolve a drive.
       load: (drive) => fileInfo | null,
      
       run: (path) => Promise
      }

      Each piped drive will recieve a object that extends nofs's fileInfo object:

      {
       // Set the contents and return self.
       set: (String | Buffer) => fileInfo,
      
       // The src file path.
       path: String,
      
       // The dest root path.
       to: String,
      
       baseDir: String,
      
       // The destination path.
       // Alter it if you want to change the output file's location.
       // You can set it to string, warp will auto-convert it to object.
       // It's "valueOf" will return "kit.path.join dir, name + ext".
       dest: { root, dir, base, ext, name },
      
       // The file content.
       contents: String | Buffer,
      
       isDir: Boolean,
      
       stats: fs.Stats,
      
       // Alter it to control the left drives dynamically.
       drives: [Function],
      
       // All the globbed files.
       list: Array,
      
       driveList: Array,
      
       // The opts you passed to "kit.warp", it will be extended.
       opts: Object
      }

      Each drive can have a onEnd: (fileInfo) -> Any | Promise function, which will be called after a file's whole warp is ended.

      The drive can have a isReader property, which will make the drive override the default file reader.

      The drive can have a isWriter property, which will make the drive override the default file writer.

      If a drive overrides another, it can call fileInfo.super() to use it again.

    • example:

      // Define a simple workflow.
      kit.warp('src/**/*.js')
      .load((fileInfo) =>
          fileInfo.set('/* Lisence Info */' + fileInfo.contents)
      )
      .load(jslint())
      .load(minify())
      .run('build/minified');
      
      // Override warp's file reader with a custom one.
      let myReader = kit._.extend((f) =>
          kit.readFile(f.path, 'hex').then(f.path)
      ), {
       // This will tell warp you want use your own reader.
       isReader: true
      });
      
      // Override writer.
      let myWriter = kit._.extend((f) => {
       if (f.dest === 'a.js') return;
      
       // Call the overrided writer.
       f.super();
      }, { isWriter: true, onEnd: () => {
         super();
         kit.log(this.list);
      });
      
      kit.warp('src/**/*.js')
      .load(myWriter)
      .run('dist');
      
      // Use nokit's built-in warp drives.
      let drives = kit.require('drives');
      kit.warp('src/**/*.coffee')
      .load(drives.coffee());
      .run('dist');

drives

Quick Start

Here it will automatically lint, compile, compress and cache files by their extensions. You can goto Drives section to see what extensions are supported, or write your own.

let kit = require('nokit');
let drives = kit.require('drives');

kit.warp('src/**/*.@(jade|less|coffee|ls)')
    // // To disable cache.
    // .load drives.reader isCache: false
    .load(drives.auto('lint'))
    .load(drives.auto('compile', { '.coffee': { bare: false } }))
    .load(drives.auto('compress'))
    .load(concat('main.js'))
.run('dist/path');

Write your own drives

Nokit has already provided some handy example drives, you can check them in the Drives section. It's fairly easy to write your own.

let kit = require('nokit');
let coffee = require('coffee-script');

// A drive for coffee, a simple curried function.
let compiler = (opts) => function () {
    // Change extension from '.coffee' to '.js'.
    this.dest.ext = '.js';
    this.set(coffee.compile(this.contents, opts));
};

// A drive to prepend lisence to each file.
// Here "fileInfo.set" is the same with the "@set".
let lisencer = (lisence) => function (fileInfo) {
    this.set(lisence + '\n' + this.contents)
}

// A drive to concat all files. It will override the default writer.
let concat = (outputFile) => {
    let all = '';

    // Object.assign
    return kit._.assign(function () {
        all += this.contents;
    }, { isWriter: true, onEnd: function () {
        // This will enable the auto-cache.
        this.deps = kit._.pluck(this.list, 'path');

        this.dest = this.to + '/' + outputFile;
        this.set(all);

        // Call the overrided writer.
        // Call two times and create two output files.
        this.super().then(() => {
            this.dest = this.dest + '.info';
            this.set = '/* info */\n' + all;
            this.super();
        });
    } });
};

kit.warp('src/**/*.coffee')
    .load(compiler(bare: true))
    .load(lisencer('/* MIT lisence */'))
    .load(concat('bundle.js'))
.run('dist')
.then(() => {

});

      It will use stylus.set to iterate opts and set the key-value, is the value is not a function.

      }
    • return: { Function }

    • example:

      kit.drives.stylus({
