Thinking:
The user is asking about how to add pre-commit to enforce strong code formatting for this project. They mention “such project” but haven’t provided any context about what type of project this is. Let me first explore the repository structure to understand the project type and existing setup.
I should:
- First check what files are in the current directory to understand the project structure
- Look at package.json, setup.py, or other configuration files to determine the tech stack
- Provide appropriate pre-commit configuration recommendations based on the stack
- Show them how to set up pre-commit hooks to enforce formatting

Thinking:
From the glob results, I can see this is a React + TypeScript project (Vite-based, based on vite.config.ts and package.json). There are existing configuration files like eslint.config.js, tsconfig.json, package.json, and .gitignore. There’s no pre-commit configuration yet (nor a .pre-commit-config.yaml file).
Let me check the package.json to understand the TypeScript/JavaScript setup better, and then provide guidance on adding pre-commit hooks.
I’ll read the package.json and the existing configuration files to understand the tech stack, then create a pre-commit configuration.

Thinking:
This is a React + TypeScript project using Vite. It already has:
- ESLint setup with typescript-eslint and React hooks plugins
- TypeScript with strict configuration
- A lint script: “lint”: “eslint .”
To add pre-commit hooks to enforce code formatting, I need to:
- Check if there are any formatters already in use (like Prettier)
- Create a .pre-commit-config.yaml file
- Install pre-commit framework
- Optionally add format-on-save hook or other linters
Since the project doesn’t have Prettier in dependencies, I’ll suggest using either ESLint for checking (with Prettier for formatting if desired) or just ESLint. Let me check if they already want to use a specific formatter.
The user wants to “add pre-commit to enforce strong code format”. This typically means:
- Install and configure pre-commit framework
- Set up hooks that run before every commit
- Use linters/formatters like ESLint, Prettier, etc.
I’ll provide a step-by-step approach:
- Create .pre-commit-config.yaml with hooks for ESLint, TypeScript type checking, and optionally Prettier
- Install pre-commit framework
- Show them the commands
Let me create the configuration and explain the steps.
Based on your React + TypeScript project with ESLint, here’s how to add pre-commit hooks:
- Create
.pre-commit-config.yaml:
repos:
- repo: https://github.com/pre-commit/mirrors-prettier
rev: v4.0.0-alpha.8
hooks:
- id: prettier
types_or: [tsx, ts, css, html, json]
- repo: https://github.com/eslint/eslint
rev: v9.39.4
hooks:
- id: eslint
files: \.[jt]sx?$
args: ['--fix']
- repo: https://github.com/compilerla/typescript-pre-commit
rev: v1.1.0
hooks:
- id: tsc
args: [--noEmit]
- Install pre-commit:
pip install pre-commit
- Set up hooks:
pre-commit install
pre-commit install --hook-type commit-msg
pre-commit install --hook-type pre-push
Alternatively, if you don’t want Prettier (since you have ESLint), omit the Prettier hook and keep only ESLint and TypeScript.
Would you like me to create the config file and install the hooks?
