Learn Angular Tutorial Part 2. Contents. Lab 6 Components and Modules Running your first Angular ApplicationIn the previous labs we looked in to basics of Angular, Node, Type. Script, Loaders ad Bundlers. In this lab we will configure Angular environment and we will try to create the basic Customer screen and make it up and running. So lets start with the first step downloading angular framework and configuring typescript compiler. So lets create a folder called as Angular and open the same using VS code. Please refer Lab 3 on how to use VS code. In case you want to Angular using visual studio you can see this video https www. Mgvi AV e. Y. If you are eclipse guy please mail me at questpondquestpond. So as we discussed in Lab 1 that Node has npm which helps us to get Java. Script open sources. So create a package. VS code. name angular quickstart. ISC. dependencies. Dependencies. If all the npm install runs successfully you should see a nodemodules folder in your VS code project directory with the following folder structure. Lodash Min Js File' title='Lodash Min Js File' />If you go inside the Angular folder you will see lot of folders like common, http, forms core and so on. Putting in simple words Angular is MODULAR. They have developed isolated components for Forms, Http, Core and so on. In Angular. JS 1. X we just had one JS file which had the whole framework. So you drag and drop that single Angular 1.

What are your most useful, most practical methods that extends builtin JavaScript objects like String, Array, Date, Boolean, Math, etc. String format trim padding. Build an atom out of protons, neutrons, and electrons, and see how the element, charge, and mass change. Then play a game to test your ideasX JS file on HTML page and you are ready with the Angular 1. X environment. But the problem with having whole framework in one JS files was that you have to include all features even if you need it or not. For instance if you are not using HTTP still that feature will be loaded. In case of Angular we have separate discrete components which makes Angular awesome. This is the most crucial part of Angular. You can see that in package.

So below are couple of things you need to take care. First keep NPM updated to the latest version or else you can end up with a warning as shown at the side. AND EVEN IF YOU DO NOT GET THIS WARNING STILL KEEP THE LATEST NPM VERSION. To get the latest NPM version you need to use npm install g npm. This command will update NPM itself. Also you can get the below error which shows incompatibility between modules. For example in the below figure it says For Angular 4. Zone. js which is greater than 0. Logic Express 9 Serial Number Manger. So go to your project. DELETE nodemodules folder and do a NPM again. Errors of version mismatch can be huge as shown in the below figure. Sometimes fixing package. When you do these iterations please ensure you delete nodemodules folder so that you are not referring old versions. You can also get error as shown below ERR nottarget. This error says that the particular version number is not found. Use npm view packagename version command to get the latest version and update your package accordingly. Also in the same folder we need to create tsconfig. Do not worry on what settings are there in it we will explain as we go ahead. Remember do not OVER LEARN. For now just note that the below file defines how TSC will compile. Options. target es. Resolution node. Map true. Decorator. Metadata true,experimental. Decorators true,remove. Comments false.

Extension js. this As we said in the previous section that the whole goal of Angular is binding the model and the view. In Angular the binding code is officially termed as Component. So hence forth we will use the word Component for the binding code. In enterprise projects you can have lot of components. With many components it can become very difficult to handle the project. So you can group components logically in to modules. So hence forth I will be using two terms Components This will have the binding logic to bind the UI and the model. Modules This will logically group components. Before we start coding lets visualize the steps of coding. As we have said Angular is a binding framework. It follows MVW architecture. It binds HTML UI with the Java. Script code model. So if we visualize it will look something as shown in the image below. So lets move from right to left. So lets do the coding in the following sequence Create the model. Create the Component. Create the module. Create the HTML UI. So lets first create four folders in our project View folder This folder will contain the HTML UI. Model folder This folder will have the main business typescript classes. Component folder This folder will have the binding code which binds the HTML UI and Model. Module This folder will have code which will logically group the components. In order to create a folder in VS code you can use the New folder icon or you can right click and also create a folder. A model is nothing but a class with properties and behavior. So let us first create the customer model with three properties Customer. Name, Customer. Code and Customer. Amount. So right click on the Model folder and add a new file Customer. Keep the extension of this file as. While compiling the typescript command identifies only files with the extension. In the Customer. Customer class with three properties. In this book we will not be going through the basics of typescript, please do go through this 1 hour training video of typescript which explains typescript in more detail. Customer. Customer. Name string. Customer. Code string. Customer. Amount number 0. The next thing we need to code is the binding code. Binding code in Angular is represented by something termed as COMPONENTS. Angular components has the logic which helps to bind the UI with the model. So right click on the component folder and add Customer. Component. ts file as shown in the figure at the left. In the component we need to import two things the Angular core and our Customer model. Please note import is a typescript syntax and not Java. Script. So in case you are not following the code, please see this Learn Typescript in 1 hour video before moving ahead. Customer from. ModelCustomer. Component fromangularcoreThe first line imports the Customer class in to the Customer. Component. ts. This import is only possible because we have written export in Customer. The import and export generate code which follows Common. Js, AMD or UMD specifications. In case you are new to these specifications please see this Common. Js video which explains the protocol in more detail. Customer from. ModelCustomerLets try to understand how Customer component is located. If you see its using a relative path. In the import it says. ModelCustomer. The. So we are currently in the Component folder, so with. Model folder. The next import command imports angular core components. In this we have not given any relative path using.
