5 reasons why Deno will stop using TypeScript

A document surfaced today pointing that Deno will stop using TypeScript in its internal code, citing several problems with the current environment. Issues mentioned involve TypeScript compiling times, structuring and code organization, among others. Moving forward, Deno will use pure JavaScript for its internal code.

Deno problems with TypeScript

The unfavorable situations that the Deno team is currently experiencing while using TypeScript for its internal code are:

  • TypeScript compile time when changing files takes several minutes, making continuous compiling an excruciatingly slow process
  • The Typescript structure that they’re using in the source files that create the actual Deno executable and the user-facing APIs is creating runtime performance problems
  • TypeScript isn’t proving itself helpful to organize Deno code. On the contrary, the Deno team is experiencing the opposite effect. One of the issues mentioned is that they ended up with duplicate independent Body classes in two locations https://github.com/denoland/deno/issues/4748
  • The internal code and runtime TypeScript declarations must be manually kept in sync since the TypeScript Compiler isn’t helpful to generate the d.ts files
  • They’re maintaining two TS compiler hosts: one for the internal Deno code and another other for external user code even though both have a similar goal

Removing TypeScript in internal Deno code

The Deno team aims to remove all build-time TS type checking and bundling for internal Deno code. They’re looking forward to move all the runtime code into a single JavaScript file. However, they’ll still use a companion d.ts file to keep the type definitions and documentation.

It’s worth mentioning that Deno will stop using TypeScript only for the internal Deno code: the Deno user code will still be in TypeScript and thus type checked.

While TypeScript is sometimes seen as an improved version of JavaScript, this case is showing that in fact, it’s not. It has flaws like any other language. One of the most important ones is its slow compilation time. While small projects might not see a huge spike in compilation time when switching from pure JavaScript to TypeScript, it will be noticeable in large projects like a complex React app. Given the large size of its runtime, it’s not surprising that Deno will stop using TypeScript.

The safety of type checking during development does have its cost at compilation time. It’s not without reason that the TypeScript project has an extensive document on how to address and improve compilation time. One of the most interesting approaches is to use Project References, that allows developers to break apart a big TypeScript piece of code into smaller pieces.

Why Use WordPress? What Can You Do With WordPress?

Can you use WordPress for anything other than blogging? To your surprise, yes. WordPress is more than just a blogging tool, and it has helped thousands of websites and web applications to thrive. The use of WordPress powers around 40% of online projects, and today in our blog, we would visit some amazing uses of WordPress other than blogging.
What Is The Use Of WordPress?

WordPress is the most popular website platform in the world. It is the first choice of businesses that want to set a feature-rich and dynamic Content Management System. So, if you ask what WordPress is used for, the answer is – everything. It is a super-flexible, feature-rich and secure platform that offers everything to build unique websites and applications. Let’s start knowing them:

1. Multiple Websites Under A Single Installation
WordPress Multisite allows you to develop multiple sites from a single WordPress installation. You can download WordPress and start building websites you want to launch under a single server. Literally speaking, you can handle hundreds of sites from one single dashboard, which now needs applause.
It is a highly efficient platform that allows you to easily run several websites under the same login credentials. One of the best things about WordPress is the themes it has to offer. You can simply download them and plugin for various sites and save space on sites without losing their speed.

2. WordPress Social Network
WordPress can be used for high-end projects such as Social Media Network. If you don’t have the money and patience to hire a coder and invest months in building a feature-rich social media site, go for WordPress. It is one of the most amazing uses of WordPress. Its stunning CMS is unbeatable. And you can build sites as good as Facebook or Reddit etc. It can just make the process a lot easier.
To set up a social media network, you would have to download a WordPress Plugin called BuddyPress. It would allow you to connect a community page with ease and would provide all the necessary features of a community or social media. It has direct messaging, activity stream, user groups, extended profiles, and so much more. You just have to download and configure it.
If BuddyPress doesn’t meet all your needs, don’t give up on your dreams. You can try out WP Symposium or PeepSo. There are also several themes you can use to build a social network.

3. Create A Forum For Your Brand’s Community
Communities are very important for your business. They help you stay in constant connection with your users and consumers. And allow you to turn them into a loyal customer base. Meanwhile, there are many good technologies that can be used for building a community page – the good old WordPress is still the best.
It is the best community development technology. If you want to build your online community, you need to consider all the amazing features you get with WordPress. Plugins such as BB Press is an open-source, template-driven PHP/ MySQL forum software. It is very simple and doesn’t hamper the experience of the website.
Other tools such as wpFoRo and Asgaros Forum are equally good for creating a community blog. They are lightweight tools that are easy to manage and integrate with your WordPress site easily. However, there is only one tiny problem; you need to have some technical knowledge to build a WordPress Community blog page.

4. Shortcodes
Since we gave you a problem in the previous section, we would also give you a perfect solution for it. You might not know to code, but you have shortcodes. Shortcodes help you execute functions without having to code. It is an easy way to build an amazing website, add new features, customize plugins easily. They are short lines of code, and rather than memorizing multiple lines; you can have zero technical knowledge and start building a feature-rich website or application.
There are also plugins like Shortcoder, Shortcodes Ultimate, and the Basics available on WordPress that can be used, and you would not even have to remember the shortcodes.

5. Build Online Stores
If you still think about why to use WordPress, use it to build an online store. You can start selling your goods online and start selling. It is an affordable technology that helps you build a feature-rich eCommerce store with WordPress.
WooCommerce is an extension of WordPress and is one of the most used eCommerce solutions. WooCommerce holds a 28% share of the global market and is one of the best ways to set up an online store. It allows you to build user-friendly and professional online stores and has thousands of free and paid extensions. Moreover as an open-source platform, and you don’t have to pay for the license.
Apart from WooCommerce, there are Easy Digital Downloads, iThemes Exchange, Shopify eCommerce plugin, and so much more available.

6. Security Features
WordPress takes security very seriously. It offers tons of external solutions that help you in safeguarding your WordPress site. While there is no way to ensure 100% security, it provides regular updates with security patches and provides several plugins to help with backups, two-factor authorization, and more.
By choosing hosting providers like WP Engine, you can improve the security of the website. It helps in threat detection, manage patching and updates, and internal security audits for the customers, and so much more.

TypeScript — Compilation & the TypeScript Compiler

TypeScript provides a command-line utility tsc that compiles (transpiles) TypeScript files (_.ts_) into JavaScript. However, the tsc compiler (short for TypeScript compiler) needs a JSON configuration file to look for TypeScript files in the project and generate valid output files at a correct location.

When you run tsc command in a directory, TypeScript compiler looks for the tsconfig.json file in the current directory and if it doesn’t find one, then it keeps looking up the directory tree until it finds one. The directory where the tsconfig.json is located is considered as the root of the project.

You can manually provide a path to the tsconfig.json file using --project or -p command-line flag. This file doesn’t need to have the tsconfig.json filename if you are using this flag with the exact file path. However, you can also provide the directory path that contains the tsconfig.json file.

$ tsc -p /proj/x/tsconfig.dev.json

If the TypeScript compiler fails to locate this configuration file, you would get an error. But you can provide settings enlisted in this file through the equivalent command-line options which we will cover in the next lesson.

Structure of tsconfig.json

So what does this file contain and what exactly it controls?

{
  "files": [
    "src/lib/person.ts",
    "src/lib/student.ts",
    "src/main.ts"
  ],
  "compilerOptions": {
    "target": "ES6",
    "module": "CommonJS",
    "outDir": "./dist/development"
  }
}

The tsconfig.json file is a standard JSON file, however, it supports JSON5 specifications, so you can use comments, single quotes, and more. It contains some root-level options and some compiler options. The root-level options are options that are outside of the compilerOptions object, so in the above example, files is a root-level option.

The root-level options control how the project is presented to the TypeScript compiler, such as which TypeScript files to consider for the compilation. The compiler options contain settings for the TypeScript compiler such as where to output the compiled JavaScript files in the project directory.


ROOT-LEVEL OPTIONS

These options control how the project is presented to the TypeScript compiler for the compilation and static type analysis. These options must be kept outside compilerOptions object of the tsconfig.json file.

● files

The files array contains the location of the TypeScript files to consider for the compilation. These can be either relative paths or absolute paths on the disk. A relative path is located relative to the location of the tsconfig.json file (AKA root of the project).

/projects/sample/
├── a.ts
├── src/
|  ├── b.ts
|  ├── c.ts
|  ├── ignore.ts
|  └── lib/
|     ├── d.ts
|     └── e.ts
└── tsconfig.json

Let’s consider that we have the above directory structure in our project. As you can see, the TypeScript files (.ts) are located in multiple directories. We want to compile all the .ts files except the ignore.ts file. Hence we would provide relative paths of these files in the files options of tsconfig.json.

// tsconfig.json

{
    "files": [
        "a.ts",
        "src/b.ts",
        "./src/c.ts",
        "src/lib/d.ts",
        "./src/lib/e.ts"
    ]
}

You can also provide absolute paths of these files but relative paths are most recommended since they would be consistent on all the systems. All the relative paths are resolved against the path of tsconfig.json file in the project. You can optionally provide ./ or ../ prefix to locate the file.

Since we haven’t provided any compilerOptions values, all the default values for the compiler options are used which we will talk about in a bit. The TypeScript compiler compiles these files and outputs the JavaScript with .js extension by keeping the same file name as the individual input file.

The TypeScript compiler also preserves the original file path, hence the .js output file will be generated where the input file was in the directory structure. When you run the tsc command from the directory where your tsconfig.json file is located, you are going to see the result below.

/projects/sample/
├── a.js
├── a.ts
├── src/
|  ├── b.js
|  ├── b.ts
|  ├── c.js
|  ├── c.ts
|  ├── ignore.ts
|  └── lib/
|     ├── d.js
|     ├── d.ts
|     ├── e.js
|     └── e.ts
└── tsconfig.json

As you can see, the TypeScript compiler compiled all the input TypeScript files listed inside files array of tsconfig.json. You can’t see the ignore.js file since ignore.ts file was not included in the files array.

The directory where the tsconfig.json file is located is considered as the root of the project, AKA the root directory. You can also include a file from outside this root directory, such by including "../x.ts" in the files array where x would be in the parent directory of the root directory. Since the TypeScript compiler preserves the input file path, it will generate x.js in the parent directory of the root directory.

● include & exclude

The files option is great when you have relatively few files to work with. But when your project is big and contains hundreds of source files located in a nested directory structure, then handpicking file paths is not practical.

To solve this issue, we can use include option. This option is just like files, however, we can optionally provide glob patterns to locate input files. The exclude options behave the same, except it removes the files from the compilation that may have been included by the include option.

// tsconfig.json

{
    "include": [
        "a.ts",
        "src/**/*.ts"
    ],
    "exclude": [
        "./**/*/ignore.ts"
    ]
}

In the above tsconfig.json, we have removed the files option and added include which adds a.ts file from the root directory and all the .ts file from the src directory. Since this would also include any ignore.ts from the src directory, we have provided the exclude option that excludes any ignore.ts file from the compilation if located inside the src directory.

When we run the tsc command now, results won’t be any different since the files considered for the compilation both in the previous example and this example are the same.

/projects/sample/
├── a.js
├── a.ts
├── src/
|  ├── b.js
|  ├── b.ts
|  ├── c.js
|  ├── c.ts
|  ├── ignore.ts
|  └── lib/
|     ├── d.js
|     ├── d.ts
|     ├── e.js
|     └── e.ts
└── tsconfig.json

The TypeScript compiler automatically excludes files from the "node_modules""bower_components""jspm_packages" and "<outDir>" directories, where <outDir> is the value of outDir compiler-option provided by you. This prevents any .ts file from these directories getting included in the compilation process by accident.

How to Use TypeScript and Deno to Build a CLI

Discover how to use Typescript and Deno to build a CLI.

Twilio Programmable SMS includes an HTTP REST API that makes it easy to interact with the SMS API. Once an SMS message request is created with the REST API, its status can be retrieved using another endpoint. By incorporating that REST API you can build a Deno CLI application that sends the message and reports on its delivery.

Deno is a new runtime environment for JavaScript that provides the capabilities of Node.js without the heavyweight package deployment and complex package management required for Node.js applications.

Deno provides new features to support the wide range of contemporary server-side applications being developed with JavaScript, a range that wasn’t envisioned when Node.js was developed.

Deno includes native support for TypeScript; no additional components are required. An application written with Deno can also be launched “remotely” - the user can execute the script specified by the URI pointing to a file hosted on the web. Deno will automatically download the script and other required dependencies to run the program.

Thanks to Deno modularity, you can build a program that utilizes existing code to create an SMS message request and monitor its status. Like other programming languages, Deno supports command line arguments, so you can create a CLI program to achieve anything you want.

Important compliance note: There are rules for using SMS messaging and they vary between countries. Familiarize yourself with the countries’ rules in which you’ll be sending messages with the Twilio Regulatory Guidelines for SMS.

Understanding the tutorial project

This tutorial will show you how to create a CLI program using Deno. To demo Deno features, you’ll be writing a CLI program that sends an SMS message to a phone number and reports the message delivery status. Unlike the Twilio CLI, this program will report the message delivery status without the need to execute another command. You’ll use the TwilioSMSHelper, which utilizes Twilio Programmable SMS to send the messages with Twilio’s REST API.

You’ll learn how to read command line arguments in Deno using the yargs library. You’ll find out how to register the arguments alias shortcuts (–argument, -a). You’ll also learn how to fallback to environment variables if the user doesn’t provide some of the arguments - for this purpose you will use lodash. You will also learn how to utilize the difference() method from lodash to compare two object keys and verify that the provided input doesn’t miss any values.
