@reinjs/rein-loader v1.0.4

rein-loader

The framework loader of rein.

Install

npm i @reinjs/rein-loader

Usage

We can use addCompiler to expose compilers.

const Loader = require('@reinjs/rein-loader');
const loader = new Loader();
loader.addCompiler(name, callback);
loader.addProgram(dir);
loader.compile();

• addCompiler it has two args.
  • name the compiler name
  • callback how to build data with args of dir
• addProgram it has one arg of dir which tell compiler how to build under the dir.
• compile build the data method.

System Compilers

We can got some compilers easily by system.

Controller Compiler

Arguments:

• options
  • pathname how to build dir by arg of dir.
  • ...args

e.g.

loader.addControllerCompiler(Object.assign(
  config.controller || {},
  {
    inject: this.app,
    target: this.app.controller = {},
    pathname: this.makePathname(scope, 'controller')
  }
));

Middleware Compiler

Arguments:

• options
  • pathname how to build dir by arg of dir.
  • ...args

e.g.

loader.addMiddlewareCompiler(Object.assign(
  config.middleware || {},
  {
    inject: this.app,
    target: this.app.middleware = {},
    pathname: this.makePathname(scope, 'middleware')
  }
));

Service Compiler

Arguments:

• options
  • pathname how to build dir by arg of dir.
  • ...args

e.g.

loader.addServiceCompiler(Object.assign(
  config.service || {},
  {
    inject: this.app,
    target: this.app.service = {},
    pathname: this.makePathname(scope, 'service')
  }
));

Extend Compiler

loader.addExtendCompiler(property, file, options)

Arguments:

• property the name of extending
• filecallback how to get dir by arg of dir?
• options

• target which object can been built on?
• inject inject object
• override can override properties?
• originalPrototypes original prototypes from koa or other framework

It also has four custom methods by alias name:

In KOA:

• addContextCompiler extend context.js
• addRequestCompiler extend request.js
• addResponseCompiler extend response.js
• addApplicationCompiler extend application.js

this.loader
  .addContextCompiler(this.extendCondition(this.app.context, scope, 'extend/context.js'))
  .addRequestCompiler(this.extendCondition(this.app.request, scope, 'extend/request.js'))
  .addResponseCompiler(this.extendCondition(this.app.response, scope, 'extend/response.js'))
  .addApplicationCompiler(this.extendCondition(this.app, scope, 'extend/application.js'));

Message Compiler

On agent you should add this compiler for ipc sender.

this.loader.addMessageCompiler(inject, fileCallback);

Arguments:

• inject inject object
• fileCallback hwo to get dir by arg of dir?

this.loader.addMessageCompiler(this.app, ({ type, pathname }) => {
  if (type === 'project') return path.resolve(pathname, `app/${this.app.name}.js`);
  return path.resolve(pathname, 'app/message.js');
});
