海外TECH	DEV Community	Everything you need to know about Execution Context in JavaScript	https://dev.to/nayyyhaa/everything-you-need-to-know-about-execution-context-in-javascript-2jha	Everything you need to know about Execution Context in JavaScriptOkay You might be writing your code in JavaScript for ages you know what logic to use when but have you ever wondered how variable or function created holds information about its environment Well there s something called Execution Context which gets created by our JS Engine which does all the magic in the background Let s demystify it in this article What is Execution Context By the name we can decode it as Execution to execute out code Context specific environmentHence Execution Context provides information about our environment where our specific code is stored and executed Whenever a script is executed by the JS engine a new execution context is created By default Global Execution Context is created Global Default Execution ContextIt is the first thing that is created when we write JavaScript code Hence referred to as Default Context Since JS is a single threaded language only one Global Execution Context GEC is created for executing the code It has two phases Creation phase Execution phaseLet s dive deep into it Creation PhaseIn this phase the compilation of JS code is done but doesn t involve the execution of code Let s consider the following program let x function printHello console log Hello Kitty printHello When we debug this program with our developer s tool of our browser we could notice that the value of x variable is coming as undefined in our scripts and Hello Kitty has not been printed in our console Also there s something called window present in our global scope This means in Creation Phase following this happens variables initialized with undefined valuefunctions declared and initialized but are NOT executed yetwindow global object gets created holds information about function arguments variables as well as inner functions declaration this created which points to the global object created aboveTo sum it up Image src Execution Context Finally Our code gets executed in this phase JS engine executes the code line by line where all the variables are finally initialized with their value and functions get invoked For each function invocation Functional Execution Context gets created Let s learn about this Functional Local Execution ContextWhenever a new function gets called a new execution context is created with basic two phases The creation phase and the execution phase This new execution context is known as Local Functional Execution Context FEC Hence in the above code while parsing the function invocation we could notice our function being present in the local scope This FEC is similar to GEC the difference is that it creates the arguments object instead of creating the global object where this points to the current object Hence In Execution Phase Image src Visual RepresentationSince for each function invocation gt new execution context is created Let s visualize this whole concept Image src and this feels trippy ‍For ease of storing Global Execution Context and all Local Execution Context we have a data structure called Call Stack Whenever a new execution context is created it gets stacked above the previous execution context and so on The JS engine takes care of keeping track of this stack s execution so that one execution context gets executed at a time to maintain the Single threaded nature of JS Wrap upGreat Now we know what execution context it and why is it so useful for our beloved JS engine ️We got a good grasp of the differences between Global Execution Context amp Local Execution Context along with the phases required in their creation Thanks for reading	2021-09-17 19:38:43
海外TECH	DEV Community	Couchbase CRUD with .Net Core	https://dev.to/parasmm/couchbase-crud-with-netcore-5217	Couchbase CRUD with Net CoreRecently I got an opportunity to work on Net Core with Couchbase I wanted to share steps to create a new Net Core Web API and implement CRUD operations with Couchbase as backend Pre requisites Install Couchbase Community Edition Install sample bucket “travel sample DotNet Core SDK Visual Studio Code What is Couchbase Couchbase Server is an open source distributed JSON document database It exposes a scale out key value store with managed cache for sub millisecond data operations purpose built indexers for efficient queries and a powerful query engine for executing SQL like queries More details can be found at their site here Create new WebAPI project Execute below command to create a new Net project of type webapidotnet new webapi name CouchbaseWebAPI Add Package reference Package References and versions added for this example Couchbase Extensions DependencyInjection Version CouchbaseNetClient Version Run below command in the project folder dotnet add package Couchbase Extensions DependencyInjection version dotnet add package CouchbaseNetClient version dotnet restore Update appsettings json Update appsettings json to include required configuration for Couchbase In default generated appsettings json file you can add below configuration after the setting for AllowedHosts Couchbase ConnectionString couchbase UseSsl false UserName lt Couchbase userid gt Password lt Couchbase password gt Update ConfigureSevices to add Couchbasepublic void ConfigureServices IServiceCollection services services AddControllers services AddCouchbase Configuration GetSection Couchbase services AddCouchbaseBucket lt INamedBucketProvider gt travel sample AddCouchbase is an extension method from “Couchbase Extensions DependencyInjection which allows us to add couchbase configurations to your application This is reading all the settings from appsettings json which we updated in last step AddCouchbaseBucket is an extension method which allows us to add a particular bucket to the system While accessing documents application will be looking at travel sample bucket to work with documents This has wired up dependency injection for the application Now based on this in our controller class where we want to work with travel sample bucket we update the class As we are about to interact with Airport documents from the travel sample bucket lets create a Controller class as AirportController private readonly IBucket bucket public AirportController INamedBucketProvider bucketProvider bucket bucketProvider GetBucketAsync GetAwaiter GetResult Here in AirportController s constructor dependency injection is requesting for INamedBucketProvider part of “Couchbase Extensions DependencyInjection object which based on ConfigureServices above gets couchbase bucket “travel sample assigned to bucket which is of type IBucket part of “Couchbase Now the controller is wired up to work with buckets We can dive into individual endpoints for CRUD operations Let s start with Read CRUD Read Create model classes named Airport and Geo public class Airport public string airportname get set public string city get set public string country get set public string faa get set public Geo geo get set public string icao get set public int id get set public string type get set public string tz get set public class Geo public double alt get set public double lat get set public double lon get set Add below function in AirportController for HttpGet verb HttpGet Route Id public async Task lt Airport gt Get string Id Get default collection object var collection await bucket DefaultCollectionAsync Get single document using KV search var getResult await collection GetAsync Id return getResult ContentAs lt Airport gt Access below link to get response from above functionality https localhost Airport airport airport is a key in the travel sample bucket we installed The key format in this sample bucket is type Id where type is the document type here airport And the Id is the unique identifier of the document here The same format has been used in Create update and delete below Next let us look at Create CRUD Create Add an HttpPut endpoint as below HttpPut public async Task put FromBody Airport airport if airport id throw new Exception Error in input data Id should not be set get default collection of the bucket var collection await bucket DefaultCollectionAsync defaulting the id value to insert New Id generation has different approaches which is not discussed here airport id using the collection object insert the new airport object await collection InsertAsync lt Airport gt airport airport id airport Here we ve hard coded airport Id as and the same value is being passed for the key name in InsertAsync call This will throw an error Couchbase Core Exceptions KeyValue DocumentExistsException for subsequent calls as soon as one record is entered in the couchbase DB with Id as Note generating a new Id has couple of different approaches which is outside scope of this article Next up is update CRUD Update Add an HttpPost endpoint as below HttpPost public async Task post FromBody Airport airport if airport id throw new Exception Error in input data Id is required get default collection of the bucket var collection await bucket DefaultCollectionAsync call ReplaceAsync function to save the modified version of the document await collection ReplaceAsync lt Airport gt airport airport id airport ReplaceAsync function of collection object can be used to modify update replace the document The first parameter is the KV search Key for the given document Same as read the key is in format type id Additionally Couchbase SDK provides us with UpsertAsync function as well which as names suggest is for update or insert Lastly let us look at Delete CRUD Delete Add HttpDelete endpoint to our controller HttpDelete Route Id public async Task delete string Id if string IsNullOrEmpty Id throw new Exception Error in input data Id is required var collection await bucket DefaultCollectionAsync Id contains key in required k v search e g airport await collection RemoveAsync Id RemoveAsync function of collection object removes the document associated with key provided in input “Id Bonus Custom Bucket Provider Additionally if we want to access multiple buckets from the system we can use below method If we want to access multiple buckets we need to create interfaces which extend from INamedBucketProvider and use that provider while adding it to controllers e g public interface ICustomBucketProvider Couchbase Extensions DependencyInjection INamedBucketProvider public interface ICustomBucketProvider Couchbase Extensions DependencyInjection INamedBucketProvider And change the Configure services function as below services AddCouchbaseBucket lt ICustomBucketProvider gt travel sample services AddCouchbaseBucket lt ICustomBucketProvider gt gamesim sample Now in controller we can add reference to both these buckets asprivate readonly IBucket bucket private readonly IBucket bucket public AirportController ICustomBucketProvider bucketProvider ICustomBucketProvider bucketProvider bucket bucketProvider GetBucketAsync GetAwaiter GetResult bucket bucketProvider GetBucketAsync GetAwaiter GetResult The above code will wireup bucket with travel sample bucket and bucket with gamesim sample Please refer below link for complete code sample Conclusion So we went through wiring up Net Core web api with Couchbase SDK and Couchbase dependency injection Created endpoint to work with Airport documents from travel sample bucket provided by Couchbase Created all the usual endpoints for CRUD operations Additionally we saw how to connect to more than one bucket in the application References	2021-09-17 19:26:34
