Can typescript be used for backend

There are many generic programming languages out there, but they all have one thing in common: they can be used for the front-end and backend. That said, not all of them are built specifically for the web (which is where most developers spend their time). In this article I’ll go over what exactly makes a language good at building web apps, then show how typescript stacks up against other languages when it comes to being used as a backend.

Typescript is very well suited for backend because of its static typing.

Typescript is a superset of Javascript, which means that it has all the features that javascript has. For example, you can use TypeScript to create a web server with Nodejs.

Typescript also offers type safety and strong types. This means you can have less errors when programming in Typescript because it checks for types at compile time instead of at runtime (like in JS).

Typescript also has a build process where it compiles your code into something called “bytecode” which makes it run faster than regular Javascript does by using V8 engine (the same one used by Chrome). Get to know about typescript vs javascript performance.

Typescript supports async/await.

Async/await is a new feature in Typescript 2.8 that makes asynchronous programming easier. This allows you to write functions that return Promises but without having to use the callback pattern. For example:

async function getUser(id) {

return await someServiceThatDoesntExist();

Typescript’s type system is strong and can help avoid many bugs.

One of the most important aspects of Typescript is its strong type system. This means that all variables, parameters and functions must be declared with a specific type or they will not be allowed in your program. For example, if you define a variable as a string value it will force you to use only string literals in that variable’s initialization expression.

This strong typing allows TypeScript to catch many bugs at compile time instead of run-time which helps improve code quality and readability.

There are a lot of great 3rd party libraries that can be used in typescript.

There are a lot of great 3rd party libraries that can be used in typescript. Here are a few examples:

  • Express, a popular Node framework for building web applications.

  • Mongoose, an object mapper for MongoDB written in JavaScript (but works with TypeScript as well).

  • Hapi, another popular framework for building APIs.

  • Redis, client library for the Redis in-memory database.


I don’t think you will find a framework that is more suited to TypeScript than Angular. Angular is built on top of TypeScript, and it has been designed with the best possible support for typed languages like TypeScript in mind. It’s one of the reasons why I decided to use Angular over React: because there’s no need to learn another language if you already know TypeScript!

Finding The Best Among LPG And Natural Gas Heaters

Natural gas heating can convey a warm and agreeable home without an awkward vitality bill. Gas heaters are eco-friendly, conservative, and solid, as well as the ideal method to remain cozy and warm during the virus winter months.

LPG gas heaters and natural gas heating are both vitality proficient and an awesome method to heat your home. LPG gas heaters and natural gas heating is quick and gives genuine warmth.

Maintain a strategic distance from these run of the mill botches when looking for the best LPG gas heaters and you should wind up with a splendid gas heating purchase that flawlessly suits your home.

  1. Choosing an inappropriate fuel

There are two types of gas heaters available to be purchased, natural gas heaters for homes and LPG gas heaters. Gas heaters are made for use with just one gas type and won’t work securely with different gaseous powers.

There are two main differences in the manner that LPG (Propane) gas heaters and natural gas (Methane) heating work. The principal difference is in the vitality content. LPG has a higher calorific worth or vitality content, so less gas is required to deliver a similar measure of heat.

The subsequent difference is in the oxygen to gas proportion required for legitimate ignition. LPG gas heaters expect oxygen to the gas proportion of roughly 25 to 1. Natural gas heating requires a proportion of around 10 to 1. To accomplish this difference, LPG is ordinarily given in a smaller amount yet at a higher weight, drawing more oxygen with it into the burner. 

  1. Selecting an inappropriate type of gas heater

Gas heaters are comprehensively assembled as either Portable gas heaters or Flued LPG gas heaters. Within these gas heater bunches are sub-bunches including convectors, radiant-convectors, power flued, flued radiant, gas divider heaters, and radiant gas heaters.

Radiant gas heaters warm you much like the sun. Radiant heaters permit specific spaces within an indoor zone to be heated, essentially warming just the individuals and articles situated before the unit. Radiant heaters are commonly not reasonable if you need in any event, heating within a bigger space.

Convector heaters, warm your space using convection or air development. Alongside the gas burner, they incorporate a fan to help circulate the heat more equally all through space. Fan driven convection heaters are considerably more appropriate for bigger spaces, doing a greatly improved activity of even heat conveyance than radiant heaters.

In any case, if you just wish to heat a small territory within a bigger space then you ought to likewise consider if you need to purchase a flued or an unflued gas heater. For most individuals, unflued heaters are very protected to purchase when you follow the entirety of the maker’s wellbeing instructions.

  1. Getting an inappropriate size gas heater

When you pick your best natural gas heating or LPG gas heater available to be purchased, you will likewise need to choose what size unit you need, as each type comes in different heat yield models. If you purchase too small a gas heater, it won’t have the option to sufficiently heat the intended zone. If you purchase a gas heater that is too enormous will cost you additional cash and oversizing can be perilous. Keep in mind, the heat yield of the gas heater is measured in kW, not to be mistaken for the gas input.

A Guide To Dual Voltage Hair Straighteners

A dual voltage hair straightener is the one that can acknowledge both 110-120V and 220-240V which implies it can work over the world. Purchasing a dual voltage straightener implies you don’t need to purchase an extra force converter, for example, this all-inclusive fitting adapter when you travel to a different country. 

How to check if a Flat Iron is a dual voltage or not? 

Practically all-electric or electronic items start in their item portrayal of voltage necessity, read the important part on your straightener to see if it is dual voltage or not. 

If the label states as “110V-240V” then it is fine and it should work around the world. This data ought to likewise be printed somewhere on the straightener itself. Now and again you should see the phrase “wide range input”; this likewise expresses the flat iron is dual voltage and will work around the world. 

Do you need a dual voltage straightener?

If you travel different pieces of the world much of the time, then indeed, you ought to get a dual voltage straightener on the grounds that as expressed before different countries have different force officers. It is prescribed to don’t accept a flat iron since it’s a dual voltage, rather check if it has all the standard highlights typically found in the best flat irons first, dual voltage ought to be an optional component. 

The most effective method to Identify Dual Voltage Straightener

  • your nation of origin, 
  • what country you’re going to, and 
  • if you have a dual voltage good appliance or not. 

Here are three situations to choose if your hair appliance will work abroad

  • If your nation of origin and country you are voyaging have the equivalent electrical framework, then your hair appliances will work whether it’s dual voltage. You may require an adapter still. 
  • If your nation of origin and country you are voyaging has a different electrical framework AND your hair appliance is dual voltage, then your hair appliances will work abroad if you have an adapter. 
  • If your nation of origin and country you are voyaging have a different electrical framework AND your hair appliance isn’t dual voltage, then your hair appliances will work abroad if you have a converter and an adapter. 

For instance, if you are going from the United States, which runs on a 110-volt framework, to Europe, which runs on a 220-volt framework. If you don’t have a dual voltage hair curling accessory or hair straightener so you can have the decision of: 

  • purchasing a converter and an adapter to use with my current hair appliance 
  • purchasing another dual voltage appliance and an adapter 

This is on the grounds that the electrical framework in countries changes and runs on a different number of volts like the US and Europe. Hence, you have to change over how much electricity flows into your appliance to work appropriately, or something bad might happen, it could get seared. You wouldn’t need that to happen to your hair straightener or twisting wand while voyaging globally so check the voltage of your nation of origin and where you’re making a trip to. 

Converter Or Adapter-Which One To Choose? 

If you need to utilize your current hair appliance, which isn’t dual voltage, then you’ll require: 

this converter—to change over the voltage from 110 to 220 or the other way around, and 

an adapter—to adjust your nation of origin’s fitting into the meeting country’s attachment.

Heating The Basements Quickly

Having a basement is quite vain if it’s too cold to without a doubt spend time in. The problem is, basements are inherently damp and cold.
