ESLint Validation

Example of a simple project that showcase a kind of issue that ESLint is expected to report.

Configurtion file

It is expected the tool to use the .eslintrc on the root of the project when running:

  "plugins": [
    "react"
  ],
  "rules": {
    "quotes": [2, "double"]
  }

In this case, I depend on the react plugin and the rule for the quoting style of my code should be double quotes i.e strings with single quotes must be warned by ESLint.

Run the tool on Linux

• Install ESLint

  npm install -g eslint

• Install necessary plugins, in this case, only needs react

  npm install -g eslint-plugin-react

• Run the tool on the root of the repository

  eslint .

Expected results

The tool should return an error on line 4 of example.js stating that "Strings must use doublequote"
