VSCode still throwing a replaceAll warning, despite targeting ES2021

Here is the tsconfig file for my Vue project:

{
   "extends": "@vue/tsconfig/tsconfig.web.json",
   "include": ["env.d.ts", "src/**/*", "src/**/*.vue", "src/**/*.json"],
   "exclude": ["src/**/__tests__/*"],
      "compilerOptions": {
      "target": "es2021",
      "module": "ESNext",
      "lib":["ES2021", "DOM"], <-- I found that adding this line resolved warnings in Vue and .ts files
      "forceConsistentCasingInFileNames": false,
      "composite": true,
      "baseUrl": ".",
      "paths": {
         "@/*": ["./src/*"]
      },
      "allowJs": true,
      "outDir": "target",
      "noImplicitAny": false,
      "types": ["vite/client"],
      "strictNullChecks": false,
   }
 }

I initially expected to be able to use ES2021 features without errors if my target was set to ES2021 (e.g., "resresr sdf".replaceAll(" ", "") causing a function error). However, it turns out that adding "lib":["ES2021", "DOM"] was necessary to eliminate the error. Why do I need to include lib 2021?

It's worth noting that I am utilizing the Volar extension with takeover mode (https://vuejs.org/guide/typescript/overview.html#volar-takeover-mode) and have followed their recommendation to disable the TypeScript VSCode extension. Even when I had not disabled it, I still encountered the same warning.

I attempted restarting the Volar server after making changes, but unfortunately, the issue persists...

Answer №1

While it may seem like a temporary fix, explicitly targeting a specific library with the triple-slash directive can help resolve issues on a file-by-file basis. So, if you're still working out the configuration settings, consider adding the following line at the beginning of your file:

/// <reference lib="es2021" />

Answer №2

"module" and "target" are two properties of compilerOptions, but they have been mistakenly placed outside the compilerOptions object. It should be structured like this:

"compilerOptions": {
    "target": "ES2021",
    "module": "ESNext",
    ...
}
