suicchi

Better and cleaner switch case made for everyone

Installation

You can start by installing this library using the command below:

npm i --save suicchi

Run Test

npm run coverage

Basic Usage

import { Suicchi } from "suicchi";

const switchCase = new Suicchi();

switchCase.addCase("car", "Ford GT");
switchCase.addCase("name", "Rye");
switchCase.addCase("gender", "female");

const name = switchCase.evaluate("name");

console.log(name); // => "Rye"

// the above code will translate to:
// let name;

// switch ("name") {
//   case "car":
//     name = "Ford GT";¸¸
//     break;
//   case "name":˚v
//     name = "Rye";
//     break;
//   case "gender":
//     name = "female";
//     break;
//   default:
//     name = () => {}
//     break;
// }

// console.log(name);

Adding a default case

import { Suicchi } from "suicchi";

const defaultCase = "no-record";

const switchCase = new Suicchi(defaultCase);

switchCase.addCase("car", "Ford GT");
switchCase.addCase("name", "Rye");
switchCase.addCase("gender", "female");

const age = switchCase.evaluate("age");

console.log(age); // => "no-record"

// the above code will translate to
// let age;

// switch ("age") {
//   case "car":
//     age = "Ford GT";
//     break;
//   case "name":
//     age = "Rye";
//     break;
//   case "gender":
//     age = "female";
//     break;
//   default:
//     age = "no-record";
//     break;
// }

// console.log(age);

Multiple keys

import { Suicchi } from "suicchi";

const switchCase = new Suicchi();

switchCase.addCase(["car", "transportation"], "Ford GT");
switchCase.addCase("name", "Rye");
switchCase.addCase("gender", "female");

const car = switchCase.evaluate("car");

console.log(car); // will return "Ford GT"

// the above code will translate to
// let car;

// switch ("name") {
//   case "car":
//   case "transportation":
//     car = "Ford GT";
//     break;
//   case "name":
//     car = "Rye";
//     break;
//   case "gender":
//     car = "female";
//     break;
//   default:
//     car = () => {}
//     break;
// }

API

Constructor

The Suicchi Object constructor only takes in 1 optional parameter which can either a value, a function, or an object. And it generates the case depending on the type of parameter you pass in.

If you only pass in a value or a function, like the following:

const Switch = new Suicchi(() => {
  // DO OTHER THINGS...
  return 1 + 1;
});
const aSwitch = new Suicchi(() => ('aValue'));
const bSwitch = new Suicchi('anotherValue');

You'll be doing something equivalent to:

// Switch
switch(x) {
  default:
    // DO OTHER THINGS...
    return 1 + 1;
}
// aSwitch
switch(x) {
  default:
    return 'aValue';
}

// bSwitch
switch(x) {
  default:
    return 'anotherValue';
}

But if you pass in an Object, you'll be able to pass in other cases and routines besides the default case and routine, like so: (Note: if you pass in an object - the 'default' property will be required)

const cSwitch = new Suicchi({
  default: null;
  case1: "What";
  case2: () => (1234)
})

You'll be doing something similar to:

// cSwitch
switch(x) {
  case 'case1':
    return 'What';

  case 'case2':
    return 1234;

  default:
    return null;
}

AddCase

The AddCase method allows you to add new or overwrite existing cases. It takes in 2 parameters - the case and the routine.

The case can be of the following types: string, string[], or object;

if the case is an object, then the 2nd parameter, the routine, is no longer required as it should be paired into the key-value case object.

Example of use:

const x = new Suicchi();

// To assign a single case to a single routine
x.addCase("aValue", "anotherValue");

// the above is equivalent to:
switch(X) {
  case "aValue":
    return "anotherValue";

  // by default, this is already present at this point
  // as this is set upon initialization of the Suicchi object instance
  default:
    return null;
}

// To assign a multiple cases to a single routine
x.addCase(["val1", "val2"], "anotherValue");

// the above is equivalent to:
switch(X) {
  case "val1":
  case "val2":
    return "anotherValue";

  default:
    return null;
}

// To assign multiple cases to multiple routines
x.addCase({
  condition1: "12345",
  condition2: 12345,
});

// the above is equivalent to:
switch(X) {
  // ...EXISTING CASES AND ROUTINES
  case "condition1":
    return "12345";

  case "condition2":
    return 12345;

  // ...OTHER EXISTING CASES AND ROUTINES
  default:
    return null;
}

GetCases

The GetCases method will return a string array containing the existing cases that you've set for the Suicchi instance.

const x = new Suicchi({
  default: null;
  case1: "What";
  case2: () => (1234)
})

x.getCases(); // => ['case1', 'case2', 'default']
