# ts-safe-access
Hacky way to implement elvis operator (aka safe navigation) with typescript plugin.
## Module Transpiler
If you want to just get the corresponding JavaScript output given TypeScript sources.
For this you can use ts.transpileModule to get a string => string transformation like below.
## Custom Compiler
If you want get custom compiler only in addition to native tsc that's run custom transformer before compilation.
Custom compiler that will take a list of TypeScript files and compile
down to their corresponding JavaScript files.
### Source
```js
console.log(a.test?.way?.dd.cc?.uu);
console.log(ac?.test?.test2);
console.log(ac?.test[3]?.test2);
console.log(a?.test);
console.log(a.test?a.c?4:32:3)
```
### Compiled
```js
console.log((((a.test || {}).way || {}).dd.cc || {}).uu);
console.log(((ac || {}).test || {}).test2);
console.log(((ac || {}).test[3] || {}).test2);
console.log((a || {}).test);
console.log(a.test ? a.c ? 4 : 32 : 3);
```
### Install
```bash
yarn add ts-safe-access
```
```bash
npm i ts-safe-access --save --dev
```
### Usage
```bash
ttsc .ts
```
