||||
```sh
|
||||
# 进入你的目录
|
||||
cd your-directory
|
||||
## 依赖项
|
||||
|
||||
# 初始化 npm 项目

# 安装 TypeScript 和 ts-node
|
||||
npm install --save-dev typescript ts-node
|
||||
## 如何使用
|
||||
|
||||
# 初始化 TypeScript 配置
|
||||
npx tsc --init
|
||||
1. **安装依赖项：**
|
||||
|
||||
# 创建 src 目录
|
||||
mkdir src
|
||||
|
||||
# 创建你的 TypeScript 文件
|
||||
touch src/index.ts

# Prettier安装和配置
|
||||
1. 首先，安装 Prettier，在项目目录中，运行
|
||||
```sh
|
||||
npm install --save-dev prettier
|
||||
```bash
|
||||
npm install
|
||||
```
|
||||
|
||||
2. 创建一个 .prettierrc 文件来配置 Prettier。你可以在这个文件中设置你的格式化选项，例如：
|
||||
```json
|
||||
{
|
||||
"semi": true,
|
||||
"singleQuote": true,
|
||||
"tabWidth": 4
|
||||
}
|
||||
```
|
||||
# 在Eslint中使用Prettier插件
|
||||
安装 eslint-plugin-prettier 和 eslint-config-prettier
|
||||
2. **运行工具：**
|
||||
|
||||
```sh
|
||||
npm install --save-dev eslint-plugin-prettier eslint-config-prettier
|
||||
```bash
|
||||
node index.js -i <input.pdf> [-o <output.xlsx>]
|
||||
```
|
||||
|
||||
编辑.eslintrc.js文件
|
||||
```js
|
||||
module.exports = {
|
||||
"env": {
|
||||
"browser": true,
|
||||
"commonjs": true,
|
||||
"es2022": true
|
||||
},
|
||||
"extends": ["standard-with-typescript","prettier"],
|
||||
"plugins": ["prettier"],
|
||||
"overrides": [
|
||||
{
|
||||
"env": {
|
||||
"node": true
|
||||
},
|
||||
"files": [
|
||||
".eslintrc.{js,cjs}"
|
||||
],
|
||||
"parserOptions": {
|
||||
"sourceType": "script"
|
||||
}
|
||||
}
|
||||
],
|
||||
"parserOptions": {
|
||||
"ecmaVersion": "latest",
|
||||
"project": "./tsconfig.json"
|
||||
},
|
||||
"rules": {
|
||||
"prettier/prettier": "error"
|
||||
}
|
||||
}
|
||||
- `-i <input.pdf>`：指定输入的 PDF 文件名（必需）。
|
||||
- `-o <output.xlsx>`：指定输出的 Excel 文件名（可选，默认为 `transactions.xlsx`）。
|
||||
|
||||
```
|
||||
# Husky安装和配置
|
||||
```sh
|
||||
# 安装 Husky和commitlint
|
||||
npm install --save-dev @commitlint/cli @commitlint/config-conventional husky
|
||||
例如：
|
||||
|
||||
# 创建git仓库
|
||||
git init
|
||||
|
||||
# 可修改分支名
|
||||
git branch -m 旧名字 新名字
|
||||
|
||||
# 初始化 Husky
|
||||
npx husky install
|
||||
```
|
||||
创建一个名为 commitlint.config.js 的文件，内容如下：
|
||||
```js
|
||||
module.exports = {extends: ['@commitlint/config-conventional']};
|
||||
```bash
|
||||
node index.js -i bank_statement.pdf -o transactions.xlsx
|
||||
```
|
||||
|
||||
提交前检查代码风格和提交格式：
|
||||
```sh
|
||||
npx husky add .husky/pre-commit "npm run lint"
|
||||
npx husky add .husky/commit-msg 'npx --no-install commitlint --edit $1'
|
||||
```
|
||||
# 修改tsconfig.json
|
||||
可根据需要灵活配置
|
||||
3. **构建项目（可选）：**
|
||||
|
||||
## 启用`@`表示src目录
|
||||
tsconfig.json需添加设置
|
||||
```json
|
||||
{
|
||||
...
|
||||
"baseUrl": "./",
|
||||
"paths": {
|
||||
"@/*": ["src/*"]
|
||||
},
|
||||
...
|
||||
}
|
||||
```
|
||||
执行`npm install tsconfig-paths`
|
||||
如果您使用 TypeScript 并且需要构建项目，请运行：
|
||||
|
||||
# 修改package.json
|
||||
将scripts修改为
|
||||
```json
|
||||
"scripts": {
|
||||
"build": "tsc",
|
||||
"start": "node dist/index.js",
|
||||
"dev": "ts-node -r tsconfig-paths/register src/index.ts",
|
||||
"debug": "node --inspect-brk dist/index.js",
|
||||
"lint": "eslint ./src --ext .ts --fix",
|
||||
"format": "prettier --write ./src",
|
||||
"prepare": "husky install"
|
||||
},
|
||||
```bash
|
||||
npm run build
|
||||
```
|
||||
|
||||
# 设置vscode调试
|
||||
可参考以下的launch.json
|
||||
```json
|
||||
{
|
||||
"version": "0.2.0",
|
||||
"configurations": [
|
||||
{
|
||||
"type": "node",
|
||||
"request": "launch",
|
||||
"name": "Launch Program",
|
||||
"skipFiles": [
|
||||
"<node_internals>/**"
|
||||
],
|
||||
"program": "${workspaceFolder}/src/index.ts",
|
||||
"sourceMaps": true,
|
||||
"runtimeArgs": ["-r", "ts-node/register", "-r", "tsconfig-paths/register"],
|
||||
"outFiles": [
|
||||
"${workspaceFolder}/**/*.js"
|
||||
],
|
||||
"console": "integratedTerminal"
|
||||
}
|
||||
]
|
||||
}
|
||||
然后，您可以使用以下命令运行构建后的 JavaScript 文件：
|
||||
|
||||
```bash
|
||||
node ./dist/index.js -i <input.pdf> [-o <output.xlsx>]
|
||||
```
|
||||
|
||||
## 项目结构
|
||||
|
||||
```
|
||||
项目根目录/
|
||||
├── index.js # 主入口文件
|
||||
├── package.json # 项目配置文件
|
||||
├── README.md # 项目说明文档
|
||||
└── ... # 其他文件
|
||||
```
|
||||
|
||||
## 注意事项
|
||||
|
||||
- 该工具仅适用于特定格式的银行 PDF 流水文件。如果您的 PDF 文件格式不同，可能需要修改代码中的正则表达式和交易类型列表。
|
||||
- 如果 PDF 文件包含加密或复杂的布局，解析可能会失败。
