更漂亮，eslint - classProperties 解析器插件错误

Question

I'm struggling to make my prettier works correctly. When I launch format-check ( prettier --check on js,ts files) it gives me SyntaxError: This experimental syntax requires enabling the parser plugin: 'classProperties' errors in many class files (even simple ones with one property and getter) despite below configuration. When I change parser from default into something else in .prettierrc.json , then "@trivago/prettier-plugin-sort-imports" plugin doesn't work. I want to have the configuration, that doesn't give me the mentioned error and allows sorting plugin to work. Maybe I've got some conflicts on the eslint-prettier line?

Answer 1

It appears to work correctly if the following is added to .prettierrc.json to enable the required parser plugin:

"experimentalBabelParserPluginsList": ["classProperties", "jsx", "typescript"]

This was tested with prettier 2.3.2 and @trivago/prettier-plugin-sort-imports 2.0.4.

Example of complete .prettierrc.json :

{
  "semi": true,
  "trailingComma": "all",
  "singleQuote": true,
  "printWidth": 120,
  "tabWidth": 2,
  "arrowParens": "always",
  "importOrder": ["^[a-zA-Z](.*)$", "^@[a-zA-Z](.*)$$", "^[./]"],
  "importOrderSeparation": true,
  "experimentalBabelParserPluginsList": ["classProperties", "jsx", "typescript"]
}
