What is the starting point in Angular 2 before calling AppComponent.ts?
I want to to do something at the starting point of angular 2 app but I am unable to get that point. Kindly help me if any one know about this.
Thanks in advance.
Index.html is the start and it continuous main.ts and then its goes with <my-app> and goes on and on
After Index.html, systemjs.config.js is loaded. Which tells which file to run. And in systemjs.config.js , it tells to load main.ts to get started.
packages tells the System loader how to load when no filename and/or no extension
After some research, look at the below systemjs.config.js file. The comments tell what it does and when.
/**
* System configuration for Angular samples
* Adjust as necessary for your application needs.
*/
(function (global) {
System.config({
paths: {
// paths serve as alias
'npm:': 'node_modules/'
},
// map tells the System loader where to look for things
map: {
// our app is within the app folder
app: 'app',
// angular bundles
'@angular/core': 'npm:@angular/core/bundles/core.umd.js',
'@angular/common': 'npm:@angular/common/bundles/common.umd.js',
'@angular/compiler': 'npm:@angular/compiler/bundles/compiler.umd.js',
'@angular/platform-browser': 'npm:@angular/platform-browser/bundles/platform-browser.umd.js',
'@angular/platform-browser-dynamic': 'npm:@angular/platform-browser-dynamic/bundles/platform-browser-dynamic.umd.js',

'@angular/forms': 'npm:@angular/forms/bundles/forms.umd.js',

// other libraries

//For android Internet
'moment': 'npm:moment',
'jquery':'npm:jquery/dist/jquery.js',
'fullcalendar':'npm:fullcalendar/dist/fullcalendar.js'
},
// packages tells the System loader how to load when no filename and/or no extension
packages: {
app: {
main: './main.js',
defaultExtension: 'js'
},
rxjs: {
defaultExtension: 'js'
},
moment: { main: './moment.js', defaultExtension: 'js' }
}
});
})(this);
