AngularJS + Typescript === <3
Me Myself & I Paul Souche Développeur Front-end @ @paulsouche
https://github.com/paulsouche
JavaScript types... NaN === NaN //false 0.1 + 0.2 ===
0.3 //false '' == [] //true '' //false, [] true [] + [] --> '' {} + [] --> '[object Object]' [] + {} --> 0 {} + {} --> NaN ...
JavaScript types... 6 types “undefined” “boolean” “string” “number” “object” “function”
6 falsy type undefined “undefined” false “boolean” ‘’ “string” 0 “number” null “object” NaN “number”
in AngularJS You can use : • isDefined • isUndefined
• isString • isNumber • isObject • isDate • isArray • isElement • isFunction • isPrototypeOf and...
Classes types methods : • contructor • toString.call() • stackOverflow
Conclusion No strong typings in JavaScript and won’t be better
in ES6
OK Typescript
OK Typescript how do you work ? function greeter(person: string)
{ return "Hello, " + person; } var user = "Jane User"; var universalAnswer = 42; document.body.innerHTML = greeter(user); document.body.innerHTML = greeter(universalAnswer); //throw
OK Typescript how do I strong type ? interface Person
{ firstname: string; lastname: string; } function greeter(person : Person) { return "Hello, " + person.firstname + " " + person.lastname; } var user = {firstname: "Jane", lastname: "User"}; document.body.innerHTML = greeter(user);
OK Typescript what about es6 classes ? class Student {
fullname : string; constructor(public firstname, public middleinitial, public lastname) { this.fullname = firstname + " " + middleinitial + " " + lastname; } } interface Person { firstname: string; lastname: string; } function greeter(person : Person) { return "Hello, " + person.firstname + " " + person.lastname; } var user = new Student("Jane", "M.", "User"); document.body.innerHTML = greeter(user);
OK Typescript what about es6 modules ? module Validation {
export interface StringValidator { isAcceptable(s: string): boolean; } var lettersRegexp = /^[A-Za-z]+$/; var numberRegexp = /^[0-9]+$/; export class LettersOnlyValidator implements StringValidator { isAcceptable(s: string) { return lettersRegexp.test(s); } } export class ZipCodeValidator implements StringValidator { isAcceptable(s: string) { return s.length === 5 && numberRegexp.test(s); } } }
OK Typescript how do I get the compiler ? npm
install -g typescript
OK Typescript how do I watch my code ? lint
: https://github.com/palantir/tslint https://github.com/palantir/grunt-tslint https://github.com/panuhorsmalahti/gulp-tslint compile : https://github.com/k-maru/grunt-typescript https://github.com/ivogabe/gulp-typescript
OK Typescript and my dependencies ? DefinitelyTyped Interfaces : •
AngularJS • ng-route • ng-resource • ng-animate • ng-cookies • angular-ui-router & ui-bootstrap • Underscore / Lodash / Jquery ...
Un peu de code ?
OK Typescript what’s wrong with you ?
