We will discuss two ways of working with forms - template driven form and model driven forms. With a template driven form, most of the work is done in the template; and with the model driven form, most of the work is done in the component class. Let us now consider working on the Template driven form. We will create a simple login form and add the email id, password and submit the button in the form. So in app. We have created a simple form with input tags having email id, password and the submit button.
We have assigned type, name, and placeholder to it. In template driven forms, we need to create the model form controls by adding the ngModel directive and the name attribute. Thus, wherever we want Angular to access our data from forms, add ngModel to that tag as shown above.
Now, if we have to read the emailid and passwd, we need to add the ngModel across it. If you see, we have also added the ngForm to the userlogin.
The ngForm directive needs to be added to the form template that we have created. We have also added function onClickSubmit and assigned userlogin. Let us now create the function in the app. In the above app. When you click on the form submit button, the control will come to the above function.
The form looks like as shown below. Let us enter the data in it and in the submit function, the email id is already entered.

Running under Angular 2 release and when adding JsonApiModule to the imports in app. It seems that after I add JsonApiModule to the app imports it invalidates other imports, not sure if this is an issue with this module or the other but I don't have the issue unless I add JsonApiModule to the app imports. Mmm, if it's saying NgaModule maybe you just have a typo in your code, can be?
It should be NgModule. The last commits on master are very little and are not relevant. The version on NPM is the one tagged with v3. If I remove that it does not err. I worked around this by importing the angular2-jsonapi package before all angular packages with import "angular2-jsonapi" in main.
Maybe the problem is that the NgaModule uses the same name for exporting providers. I can try to rename it. I still had some type of issue going on after the change same error with the import of other modules Loading the source higher in the load order worked for now, not sure what the long term fix is. Hi, I have upgraded my project with the final version of Angular2 and install the latest version of Json-api. I am using Angular CLI, Angular 2, and angular2-jsonapi and have encountered a similar error to this on installing: "Error: Unexpected value '[Object object]' imported by the module 'AppModule'".
I updated my Angular version number to match what you commented above as well. Should have the same set up as you. I'll try downgrading Angular 2 tomorrow and see if that changes anything. Somehow the angular2-jsonapi package was removed from my package. Seems to be working great now, thank you! Skip to content.

My directory structure is:. I have also tried to import the module from src directory - same error. Any idea what can be the reason of this error? I have seen similar topics here but no answer or hint helped. Hard to say for sure but it looks like metadata from decorators are lost during transpilation.
Not sure why you are trying to use both TS and Babel. In any case this is a support question so doesn't belong here. Similar issue here. What other suggestion would you expect given that we've got no way of reproducing similar issues locally. I would love to help but there are just so many possible setups and its variants that it is next to impossible to suggest anything without debugging your local setup I'm not sure yet what is an exact problem but this issue does not belong here.
According to it it's clear that this problem appeared only after update to RC6 while using Webpack 2. I use Webpack 1 and I don't have that problem - works good.
That's why I think that it has something to do with proper Webpack 2 configuration when using RC6. You wrote that you succeeded with angular2-seed - it uses Webpack 1, not 2nd version. I know that my post is not helping, but unfortunately I haven't found the solution for that so far. I'm also having the same issue right now Not just for a 'customModule' but also for another service imported from a shared project which uses http and throws http provider error although I am importing the HttpModule properly.
Validating Confirmation Fields in Angular Reactive Forms with Angular Material
Avien I haven't found solution for that so I just use Webpack 1 for now. Avien I don't see Gulp in angular2-seedbut I see Webpack 1. The problem now is that the workflow is harder without npm link. I'm getting the error also.
ERROR Error: "mat-form-field must contain a MatFormFieldControl."
Cannot import a custom module into the imports section of NgModule without getting Unexpected value 'ButtonsModule' imported by the module 'AppModule' at. It seems that it only works if it's a full path. Madd0g it has to be with projectRoot :. I have same problem, but it is appeared with AotPlugin only.
Angular 4 - Forms
When I built debug version via awesome-typescript-loader I've got success. But I want AotPlugin. So many closed issues and I not found solution. It is very bad. Angular is bearded dinosaurIn Angular, there are two ways to work with web forms: template driven forms and reactive forms. In template driven formwe use angular directives to build the internal representation of form in the html template file.
Most of the code is written in html template file, making it sometimes difficult to understand and test. In reactive form, we build our form design in the component class instead of component template file. This provides us more flexibility, keep your logic in component class file, instead of component template file.
This makes our component template clean and simple. We can use the FormControl constructor to set the initial value of the control. Here, we are setting the empty string in the constructor. Using the template binding syntax, we bind our form control to the firstName input box in the template.
In order to display our component in the browser window, we are going to place it in the app. In reactive forms, you can access any form control state and value at any point of time. You can then manipulate the form control values from the component class or component template. As you can see in above screenshot, as we type zeptobook in our form control firstName, it is immediately displayed below.
Like you access form control value in component template file, you can access it in component class programmatically. You can manipulate value here in component class file. A form control instance has a setValue method, that you can use to update the form control value from the component class file. Now, we have to write code to call this method from button click event.
Now, when user click on this button, it will set the form control value to ZeptoBook and update this in input box and label. We can also set some initial value while creating the form control. Remember, we put empty string while creating our firstName form control. Here, we have created an age form control and initialized its value to 18 in its constructor. Accessing the age form control in the component template file.
Here you can see, Age input box and label is showing the initialized value of 18, which you can change anytime. FormGroup is used to track the value and validation state of form control. A FormGroup combines the values of each child control FormControl into single object, with each control name as the key. In the Form Group instance constructor, we have created these form control instances.
We have add a submit button, and add ngSubmit event. On pressing submit event, we are firing onSubmit function of the component class. Also, in order to display this component in browser, I have commented our previous component app-general-infoand placed our app-form-group component. See the commented line 7. When we have multiple forms, then it become very tedious and repetitive to create form controls. FormBuilder service is a easy way for generating form controls.
Here we are going to create a simple login form, having username and password form controls in component class. Now, notice the syntax, the declaration of FormGroup and FormControl are now implicit. This saves a lot of our code. We only need to have fields name with the default values. If you see, we have a submit button, and attached login function to this submit button.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

I am importing an Angular module Shared2Module which is generated from a separated library project as an Angular package. Please add a NgModule annotation. Both, the client project and the library project have the exactly the same dependency versions. Yet, the compilation error happens.
Below is the package. The only difference with the client project package. Not sure whether is an issue because package. As commented by IevhenIkonnykov in issue this: "Please add a NgModule annotation" error can be due to multiple reasons. Thank you. BUT i want to say my experiment with this error. I added this line to my package. So i was thinking to make a file index. Again thank you for inspiration.

I build the app with webpack, no errors, and when I run it I get the following error in the browser. Expected behavior I'd expect this to work the same with Angular4 or Angular2. My question is, do I need to also upgrade the common module to Angular4 for this to work?
I thought that this would already be transpiled to js when I import it in my main app module, maybe I'm wrong. Please tell us about your environment: I tested this with webpack-dev-server. I could try to create another 2 simple repos to reproduce this same scenario, but I'd need to confirm first that I can import a repo generated with Angular 2 from another project in Angular 4.
That should not be an issue, right? It's my own module. It contains some common components used by different projects.
I wanted to upgrade one of those projects to Angular 4 but without touching the commons one. What are your dependencies on your MyCommonModule? How did you specify dependency on angular?
It is among dependencies or peerDependecies?
