The ng g component plainsight/some-name makes a new directory when we use it.

The final output will be:
***
plainsight/some-name/some-name.component.ts
***
To avoid that, make use of the flat option ng g component plainsight/some-name --flat and it will generate the files without making a new folder
***
plainsight/some-name.component.ts
***

First install Bootstrap from npm:
***
npm install bootstrap@next
***
Then add the needed script files to to apps[0].scripts in angular-cli.json file:
***
"scripts": [
"../node_modules/bootstrap/dist/js/bootstrap.js"
],
***
Finally add the Bootstrap CSS to the apps[0].styles array:
***
"styles": [
"styles.css",
"../node_modules/bootstrap/dist/css/bootstrap.css"
],
***
Restart ng serve if you're running it, and Bootstrap 4 should be working on your app.

This is best solution. But if you don't restart ng serve it never works. It is strongly recommended to do this last action.

destroy or something similar may come to the CLI, but it is not a primary focus at this time. So you will need to do this manually.

Delete the component directory (assuming you didn't use --flat) and then remove it from the NgModule in which it is declared.

If you are unsure of what to do, I suggest you have a "clean" app meaning no current git changes. Then generate a component and see what is changed in the repo so you can backtrack from there what you will need to do to delete a component.

When used with async pipe:
***

***

Encode
***
public static string Base64Encode(string plainText) {
var plainTextBytes = System.Text.Encoding.UTF8.GetBytes(plainText);
return System.Convert.ToBase64String(plainTextBytes);
}
***
Decode
***
public static string Base64Decode(string base64EncodedData) {
var base64EncodedBytes = System.Convert.FromBase64String(base64EncodedData);
return System.Text.Encoding.UTF8.GetString(base64EncodedBytes);
}

.NET 4.0 has a built-in library to do this:
***
using System.Web.Script.Serialization;
JavaScriptSerializer jss = new JavaScriptSerializer();
var d = jss.Deserialize(str);
***

async Main is now part of C# 7.2 and can be enabled in the projects advanced build settings.

For C# < 7.2, the correct way is:
***
static void Main(string[] args)
{
MainAsync().GetAwaiter().GetResult();
}


static async Task MainAsync()
{
/*await stuff here*/
}

The curly braces inside backgroundImage property are wrong.

Probably you are using webpack along with image files loader, so Background should be already a String: backgroundImage: "url(" + Background + ")"

You can also use ES6 string templates as below to achieve the same effect:
***
backgroundImage: `url(${Background})`
***

You can avoid the need for .bind(this) with an ES6 arrow function.
***
VK.api('users.get',{fields: 'photo_50'},(data) => {
if(data.response){
this.setState({ //the error happens here
FirstName: data.response[0].first_name
});
console.info(this.state.FirstName);
}

});

You can post axios data by using FormData() like:
***
var bodyFormData = new FormData();
***
And then add the fields to the form you want to send:
***
bodyFormData.append('userName', 'Fred');
***
If you are uploading images, you may want to use .append
***
bodyFormData.append('image', imageFile);
***
And then you can use axios post method (You can amend it accordingly)
***
axios({
method: "post",
url: "myurl",
data: bodyFormData,
headers: { "Content-Type": "multipart/form-data" },
})
.then(function (response) {
//handle success
console.log(response);
})
.catch(function (response) {
//handle error
console.log(response);
});
***

Parent:
***

***
Child:
***
handleLangChange = () => {
var lang = this.dropdown.value;
this.props.onSelectLanguage(lang);
}
***

***
const scrollTo = (ref) => {
if (ref /* + other conditions */) {
ref.scrollIntoView({ behavior: 'smooth', block: 'start' })
}
}
