[Chartjs]-VueJS TypeScript using ChartJS – Parsing error: '}' expected

I think the issue is on the line :

const canvas = <HTMLCanvasElement> document.getElementById('myChart');

because of the case, you can use the as syntax to avoid the lint issue

const canvas = document.getElementById('myChart') as HTMLCanvasElement;

If you still have an issue check you .eslint.*, mine is like this:

module.exports = {
  root: true,
  env: {
    node: true,
  },
  parser: 'vue-eslint-parser',
  parserOptions: {
    parser: '@typescript-eslint/parser',
  },
  plugins: ['vue','typescript'],
  extends: [
    'eslint:recommended',
    'plugin:@typescript-eslint/eslint-recommended',
    'plugin:@typescript-eslint/recommended',
    'plugin:vue/essential',
    '@vue/typescript',
  ],
}

eslintrc:

module.exports = {
  root: true,
  env: {
    node: true
  },
  extends: ['plugin:vue/essential', '@vue/prettier', '@vue/typescript'],
  rules: {
    'no-console': process.env.NODE_ENV === 'production' ? 'error' : 'off',
    'no-debugger': process.env.NODE_ENV === 'production' ? 'error' : 'off',
    'prettier/prettier': [
      'warn',
      {
        printWidth: 140,
        jsxBracketSameLine: true,
        singleQuote: true,
        'no-multiple-empty-lines': ['error', { max: 2 }]
      }
    ]
  },
  parserOptions: {
    parser: 'typescript-eslint-parser'
  }
};
