const $path = require('path');
//use lf boot
const $meta = {
    root:[optional,default is application root],
    resourceroot:[optional,default is under /<root>/src/resource/],
    webroot:[optional,default is under /<root>/src/webapp/],
const $lf_boot =require("@linkfuture/boot")($meta)
const $lf_boot_web =require("@linkfuture/boot").web({beforeSetup:beforeSetupFun,afterSetup:afterSetupFun});

//beforeSetupFun, useful for connect-history-api-fallback
const app = $lf_boot_web.app;
//setup view engine 
app.set('views', $path.join(__dirname, './views'));
app.set('view engine', 'ejs');

/*auto scan routers, binding all pages and apis by using consign*/

//forward all requests to external service you configed at $lf.$config.config.service 

//boot application

//for Mocha unit test only
module.exports = app;

How to run build

    "build": "node -e \"require('@linkfuture/boot')().build().build(['js','css'],false)\"",  //default compress is true, you can set false 
    "build SQL": "node -e \"require('@linkfuture/boot')().build().build(['sql'])\"",

Global object

After init linkfuture-boot, you can use below global object directly, no need require("")

//Boot only
$lf._               //call lodash directly, 
$lf.$m              //call moment directly, 
$lf.$config.config  //read config file
$lf.$util           //utility method
$lf.$request        //promise request with retry
$lf.$cache          //store value into redis or static
$lf.$logger.silly   //write log by using winston 
$lf.$repository     //generate async function as repository base on configuration node "service", set serviceToRepository = false to off that feature
                    //example: $lf.$repository.test.h400({qs:{a:1,b:2}})
//Web Boot only
$lf.$auth           //auth model
$lf.$siteInfo       //get basic site information
$lf.$md             //an middleware to specific auth required or is it api response and setup cache time, 

How to use middleware module for auth and cache

app.get("/admin/",$ lf.$md(
            min:0, // cache time in min
            key: function (req) { //optional, cache key, required redis setup,default value is following
                return `${req.method}_${req.getUrl}`;
            api:false, //specific response type, JSON API or page, default is page
            auth:true, //is this page behind the authenciation or not, default is false
            roles:["admin"]  //array type, which role can access this page, required set auth=true,and req.user.roles = []
           res.send("Hello world");
