👝 @fxjs/handbag

Pre-requisite

• fibjs >= 0.26.0

Usage

npm install @fxjs/handbag

Sample

register one compiler for .pug file

const fxHandbag = require('@fxjs/handbag')

const fpug = require('fib-pug')
function registerPugAsHtml (vbox) {
    const compilerOptions = {
        filters: {
            typescript: require('jstransformer-typescript').render,
            stylus: require('jstransformer-stylus').render,
        }
    }

    fxHandbag.vboxUtils.setCompilerForVbox(vbox, {
        suffix: '.pug',
        compiler: (buf, info) => fxHandbag.vboxUtils.wrapAsString(
            fpug.renderFile(info.filename, compilerOptions)
        )
    })
}

const vm = require('vm')

vbox = new vm.SandBox(moduleHash)
registerPugAsHtml(vbox)

// just require one pug as rendered html string
const renderedHtml = vbox.require('./test.pug', __dirname)

you can also do like this:

const compilerOptions = {
    filters: {
        typescript: require('jstransformer-typescript').render,
        stylus: require('jstransformer-stylus').render,
    }
}

const vbox = new vm.SandBox(moduleHash)
fxHandbag.registers.pug.registerPugAsHtml(vbox, { compilerOptions })

const renderedHtml = vbox.require('./test.pug', __dirname)

APIs

vboxUtils

vboxUtils is some basic operation for one vbox generated by new vm.SandBox(...)

setCompilerForVbox(vbox: Class_SandBox, options: SetCompilerForVBoxOptions)

set one compiler function for vbox, the compiler is used for vbox.setModuleCompiler.

interface SetVboxOptions {
    suffix: string|string[],
    compiler: Function,
    compile_to_iife_script?: boolean
}

registers

Common Option

register functions support options below:

{
    // compilerOptions passed to render of register.
    compilerOptions: {...},
    // timeout that module keep required file id,
	// - if it is 0, keep module always
	// - if it is lower than 0, it would NIRVANA after remove it, that means module required would be updated after burnout_timeout.
    burnout_timeout: {...}
}

common options

registerOptions.compilerOptions

options passed to register's compiler/transpilor/renderer, view details in specified register

registerOptions.hooks

there's one emitter option with EventEmitter type in registerOptions, all key in registerOptions.hooks would be registered as emitter's event_name with handler from registerOptions.hooks[key], e.g:

{
	...
	hooks: {
		before_transpile: (payload) => {
			// print required file's information
			console.log(payload.info)
		},
		generated: (payload) => {
			// change content from every file required by this Sandbox to 'always online'
			payload.result = 'always online'
		}
	}
	...
}

supported hooks

• before_transpile
  • param payload.raw: original content's buffer
  • param payload.info: file information
• generated: payload: {result}
  • param payload.result: transpiled content

registerOptions.rollup

There's register based on rollup, its registerOptions has those options:

• options.rollup.bundleConfig: default {}, config passed to
  • const bundle = rollup.rollup({...})
• options.rollup.writeConfig: default {}, config passed to
  • bundle.write({...})
  • bundle.generate({...})
• options.rollup.onGenerateUmdName: default (buf, info) => 's'. generate name for rollup's umd/iife mode

registerOptions.burnout_timeout

In some cases, we want vbox to remove required module by ID after burnout_timeout.

For example, you are developing one website's user profile page, which rendered from path/user-profile.pug, you serve it with http.Server and mq.Routing, and require the pug file as require('path/user-profile.pug', __dirname) with special vbox generated by registers in @fxjs/handbag or by your own manual registering. You change the pug file, then you wish the next calling to require('path/user-profile.pug', __dirname) would return the latest file resource. So, you need remove the required content every other times(such as 300ms), which is burnout_timeout.

All reigsters's option in @fxjs/handbag supports burnout_timeout option.

NOTICE

nirvana

if burnout_timeout set as Integer lower than 0, after one module(with moduleId mid) removed from Sandbox(that would happend after burnout_timeout), it would be require right away. e.g.

non-nirvana mode:

• : user: burnout_timeout = 200
• : user: sandbox.require(mid)
• : ---> burnout_timeout gone...
• : sandbox.remove(mid)
• : user: sandbox.require(mid)

nirvana mode:

• : user: burnout_timeout = -200
• : user: sandbox.require(mid)
• : ---> burnout_timeout gone...
• : sandbox.remove(mid) and sandbox.require(mid)

20ms

In general, there's time-range about lower than 20ms(it's tested) when you require one file as plain via registered box in @fxjs/handbag, but it would over 20ms in these cases:

• when content of file to require is too big
• transpilation in register would spend too much time.

If you develop app based on this feature(burnout_time), notice the time-range
