Plan:
a. Create an interface for stages.
b. Change the Stage objects into instances of a new Stage class implementing the interface.
c. Move the STAGES array and TOTAL_WEIGHTS constant into a separate module.
Elaborate:
a. Create an interface for stages:
Define an interface named IStage with properties name (string), weight (number), and execution (function).
b. Change the Stage objects into instances of a new Stage class implementing the interface:
Define a Stage class that implements the IStage interface.
Replace the plain objects in the STAGES array with instances of the Stage class.
c. Move the STAGES array and TOTAL_WEIGHTS constant into a separate module:
Create a new file named stageConstants.ts.
Move the STAGES array and the TOTAL_WEIGHTS constant into stageConstants.ts.
Export the STAGES array and the TOTAL_WEIGHTS constant from stageConstants.ts.
Update the import statements in the current file to import the STAGES array and the TOTAL_WEIGHTS constant from stageConstants.ts.

Elaborate: a. Create an interface for stages:
Here is the refactored code:
---- Start code modification ----
===== Existing code: ==== export const STAGES = [ ... ];
export const TOTAL_WEIGHTS = STAGES.reduce((acc, stage) => { return acc + stage.weight; }, 0);
===== Refactored changes (version 1): ==== // STEP 1: CREATE INTERFACE interface IStage { name: string; weight: number; execution: Function; }
// STEP 2: DEFINE STAGE CLASS class Stage implements IStage { constructor(public name: string, public weight: number, public execution: Function) {} }
// STEP 3A: MOVE ARRARY AND CONSTANT INTO SEPARATE FILE (stageConstants.ts) // Moved STAGES array and TOTAL_WEIGHTS constant to stageConstants.ts
// STEP 3B: UPDATE IMPORTS import { STAGES, TOTAL_WEIGHTS } from './stageConstants';
---- End code modification ----
I have created a new file named stageConstants.ts and added the STAGES array and the TOTAL_WEIGHTS constant. Here is how it looks like:
---- Start new file stageConstants.ts ----
import { stageStarting } from "./1_stageStarting"; import { stageClassifyTask } from "./2_stageClassifyTask"; import { stageCreateModification } from "./3_stageCreateModification"; import { stageCreateModificationProcedure } from "./4_stageCreateModificationProcedure"; import { stageFinishing } from "./7_stageFinishing";
import { Stage } from './[FILE_NAME_OF_Refactored_changes]';
export const STAGES: Stage[] = [ new Stage("Starting ...", 10, stageStarting), new Stage("Understanding ...", 50, stageClassifyTask), new Stage("Conceptualising ...", 100, stageCreateModification), new Stage("Preparing Changes ...", 80, stageCreateModificationProcedure), new Stage("Finishing ...", 10, stageFinishing), ];
export const TOTAL_WEIGHTS = STAGES.reduce((acc, stage) => { return acc + stage.weight; }, 0);
---- End new file stageConstants.ts ----
//////////////////////////////////////////////////////////////////////////////// // Stage 4: Preparing Changes ... ////////////////////////////////////////////////////////////////////////////////
I will perform the following modifications:
REPLACE export const STAGES = [ ... ];
export const TOTAL_WEIGHTS = STAGES.reduce((acc, stage) => { return acc + stage.weight; }, 0); WITH // STEP 1: CREATE INTERFACE interface IStage { name: string; weight: number; execution: Function; }
// STEP 2: DEFINE STAGE CLASS class Stage implements IStage { constructor(public name: string, public weight: number, public execution: Function) {} }
// STEP 3A: MOVE ARRAY AND CONSTANT INTO SEPARATE FILE (stageConstants.ts) // Moved STAGES array and TOTAL_WEIGHTS constant to stageConstants.ts
// STEP 3B: UPDATE IMPORTS import { STAGES, TOTAL_WEIGHTS } from './stageConstants'; END_REPLACE
Now, create a new file named stageConstants.ts with the following content:
---- Start new file stageConstants.ts ----
import { stageStarting } from "./1_stageStarting"; import { stageClassifyTask } from "./2_stageClassifyTask"; import { stageCreateModification } from "./3_stageCreateModification"; import { stageCreateModificationProcedure } from "./4_stageCreateModificationProcedure"; import { stageFinishing } from "./7_stageFinishing";
import { Stage } from './[FILE_NAME_OF_Refactored_changes]';
export const STAGES: Stage[] = [ new Stage("Starting ...", 10, stageStarting), new Stage("Understanding ...", 50, stageClassifyTask), new Stage("Conceptualising ...", 100, stageCreateModification), new Stage("Preparing Changes ...", 80, stageCreateModificationProcedure), new Stage("Finishing ...", 10, stageFinishing), ];
export const TOTAL_WEIGHTS = STAGES.reduce((acc, stage) => { return acc + stage.weight; }, 0);
---- End new file stageConstants.ts ----
