Pull Request Overview

This PR implements version 1.0 features by consolidating domain entity responsibilities, separating post metadata from a central file into individual markdown frontmatter, and removing legacy functionalities (such as the Google Spread Sheet uploader and several blog-related modules). Key changes include:

• Removing several domain files (e.g. image-entity, github-upload-files, blogs, blog.entity, and app) to consolidate and streamline responsibilities.
• Dividing the translation and publish steps into separate methods.
• Updating project configuration (package.json, ESLint, and Biome) to support the new architecture and tooling.

src/domain/image-entity.ts:1

• The entire ImageEntity is removed; please ensure that its responsibilities (such as generating filenames and handling base64 encoding) are now adequately addressed in the new domain logic.

import {randomUUID} from "node:crypto";

src/domain/github-upload-files.ts:1

• The GithubUploadFileBuilder and its related functionalities are removed; confirm that the GitHub upload process is now correctly refactored and integrated elsewhere.

import {Posts} from "./posts";

src/domain/blogs.ts:27

• [nitpick] The error message contains non-English text; if the project targets an international audience, consider using consistent localization for user-facing messages.

throw new Error(`Publisher 블로그는 1개만 존재해야합니다. ${blogs.map(blog => blog.title).join(',')} 중 하나만 선택해주세요.`);

src/app.ts:1

• The removal of the app module indicates a shift in application initialization; verify that the new architecture handles the orchestration of functionality appropriately.

import {spreadSheetUploader, SpreadSheetUploaderInterface} from "./implemention/spread-sheet.uploader";

eslint.config.mjs:1

• The removal of the ESLint configuration file requires confirmation that linting is now fully managed by the updated configuration (e.g. via Biome) to maintain code quality.

import globals from "globals";

package.json:8

• The updated test script now injects environment variables; please document this change so contributors are aware of the new testing setup and required .env configurations.
