What is "twsh"?

• You can enjoy twitter on your terminal.(only post tweet)

The reason I made "twsh"

Don't you want to post tweet, when you execute command or writing code on ther terminal?

Yes, I want to post tweet.

Ok, Let's use "twsh".

My application improves the quality of life

Before creating "twsh", I was in trouble because I couldn't post tweet on the terminal.

But now, I can post tweet on the terminal, which is great.

I can realize my idea by my own programming

Until then

Be in trouble -> Ok, Let's search for appliction that can solve problem

Now

Be in trouble -> Ok, Let's create ideal application

I can obtain some technical skills

• npm publishing
• CI tools' settings
• github and git skills
• programming skills

Coding with confidence

By protected by type,

you can write source code with confidence,

because you know the type of variable foo,

the return value of function bar and

the arguments the function baz needs.

When JavaScript

import { someFunction } from './util'

const Foo = { id: 1, name: 'foo' }
const Bar = { id: 2, name: 'bar' }
const Baz = { id: 3, name: 'baz' }

const originalPeople = [Foo, Bar, Baz];
const returnValue = someFunction(originalPeople);

console.log(returnValue) // do you imagnie?

When TypeScript

import { Person, someFunction } from './util'

const Foo: Person = { id: 1, name: 'foo' }
const Bar: Person = { id: 2, name: 'bar' }
const Baz: Person = { id: 3, name: 'baz' }

const originalPeople = [Foo, Bar, Baz];
// typescript let you know what type someFunction returns
const returnValue = someFunction(originalPeople);

console.log(returnValue) // you can imagine

Easy to mentainance

By protected by type,

you can easily modify source code for new feature or refactor,

because typescript tell you the right type.

If you can write JavaScript, you can write TypeScript

TypeScript is a typed superset of JavaScript that compiles to plain JavaScript.

https://www.typescriptlang.org/

Syntatically, any regular JavaScript is valid TypeScript

Excellent code completion

As you see, typescript language server drive your programming expericnce greater by code hints and completion
