eslint-processor-vue-blocks enables ESLint to lint the content within Vue.js single-file component blocks, such as <template>, <script>, and <style>. This package extracts and processes code from these blocks, allowing ESLint to analyze and enforce coding standards within those sections independently. It significantly improves the reliability and maintainability of Vue.js applications by extending ESLint's linting capabilities into the specific syntaxes found within Vue components.
