An simple way to boot express.
- nodejs 8.0 +
- npm 5.0 +
const $consign = require('consign');
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*/
$consign({logger:$lf.$logger})
.include("src/bin/repository")
.then("src/bin/service")
.then("src/bin/controller")
.into(app);
//forward all requests to external service you configed at $lf.$config.config.service
//option = {beforeForward(apiPath, configName, option, req),afterForward(apiPath, configName, option, req)}
$lf.$forward.forwardAll("/api",option);
//boot application
$lf_boot.boot();
//for Mocha unit test only
module.exports = app; "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'])\"",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, 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 = []
}),(req,res,next)=>{
res.send("Hello world");
})- config file can either JS or JSON format
- must under resource root folder. default resource root folder is under //src/resource/
- it will always read and merge two config files. config.json and config..json.
