Walkthrough

The pull request introduces a new linting rule to the ESLint configuration file .eslintrc.json, specifically enforcing the rule "@typescript-eslint/no-unused-vars": "error". This change aims to improve code quality by marking unused variables in TypeScript files as errors during linting, while maintaining the existing configuration settings.

Poem

In the land of code, where rabbits hop,
A new rule was added, we won't stop!
Unused vars now raise a cheer,
Linting's tighter, oh so clear!
With every commit, we’ll take a stand,
For cleaner code, we lend a hand! 🐇✨

#!/bin/bash
# Description: Verify the ESLint rule configuration and check for any existing violations

# Check if the rule is properly recognized by ESLint
npx eslint --print-config .eslintrc.json | jq '.rules."@typescript-eslint/no-unused-vars"'

# Search for potential existing violations in TypeScript files
rg -t ts -t tsx '\b(const|let|var|function)\s+\w+\s*[=:][^;]*(?!.*\1\b).*$' 

#!/bin/bash
# Let's verify the ESLint configuration and potential unused variables using simpler commands

# First, verify the ESLint configuration syntax
cat .eslintrc.json

# Then, look for variable declarations that might be unused
# Using simpler patterns to check variable declarations
rg -t ts -t tsx "^\s*(const|let|var)\s+\w+\s*=" --no-heading

# Check if there are any existing ESLint disable comments for unused vars
rg -t ts -t tsx "eslint-disable.*@typescript-eslint/no-unused-vars" --no-heading

#!/bin/bash
# Let's verify the configuration and potential impacts with correct file extensions

# Check if there are any TypeScript/React files
fd -e ts -e tsx

# Look for variable declarations in TypeScript files
rg "^\s*(const|let|var)\s+\w+\s*=" -g "*.{ts,tsx}"

# Check for any ESLint disable comments for unused vars
rg "eslint-disable.*@typescript-eslint/no-unused-vars" -g "*.{ts,tsx}"

# Verify if there are any other ESLint configurations that might conflict
fd -e json -x grep -l "eslint" {}

Our Pull Request Approval Process

We have these basic policies to make the approval process smoother for our volunteer team.

Testing Your Code

Please make sure your code passes all tests. Our test code coverage system will fail if these conditions occur:

1. The overall code coverage drops below the target threshold of the repository
2. Any file in the pull request has code coverage levels below the repository threshold
3. Merge conflicts

The process helps maintain the overall reliability of the code base and is a prerequisite for getting your PR approved. Assigned reviewers regularly review the PR queue and tend to focus on PRs that are passing.

Reviewers

Do not assign reviewers. Our Queue Monitors will review your PR and assign them.
When your PR has been assigned reviewers contact them to get your code reviewed and approved via:

1. comments in this PR or
2. our slack channel

Reviewing Your Code

Your reviewer(s) will have the following roles:

1. arbitrators of future discussions with other contributors about the validity of your changes
2. point of contact for evaluating the validity of your work
3. person who verifies matching issues by others that should be closed.
4. person who gives general guidance in fixing your tests

CONTRIBUTING.md

Read our CONTRIBUTING.md file. Most importantly:

1. PRs with issues not assigned to you will be closed by the reviewer
2. Fix the first comment in the PR so that each issue listed automatically closes

Other

1. 🎯 Please be considerate of our volunteers' time. Contacting the person who assigned the reviewers is not advised unless they ask for your input. Do not @ the person who did the assignment otherwise.
2. Read the CONTRIBUTING.md file make
