Can you explain the distinction between using tsserver and eslint for linting code?

As I work on setting up my Neovim's Native LSP environment, a question has arisen regarding JS/TS linter.

Could someone explain the distinction between tsserver and eslint as linters?

I understand that tsserver is a language server offering features such as auto-completion and go-to-definition, while eslint focuses on linting coding styles (e.g. airbnb style).

If eslint's code-format-linting feature is disabled (for example, when using prettier alongside), does it differ from other linting capabilities of eslint?

Edit:

I mistakenly conflated diagnostics with linting. The actual query I intended to ask was:

"What are the differences between tsserve and eslint for diagnostic purposes?"

Answer №1

When developing a VS Code extension for linting, you will initially need to utilize the diagnostics functionality provided by the VS Code API. This is where tools like TSLint and ESLint extensions come into play.

Language servers serve as the primary source of code diagnostics since they parse the code into an Abstract Syntax Tree (AST), making the diagnostics API also available for use.

In your specific situation, both tools can identify potential issues in your code, giving you the option to enable or disable one or both of them. Ultimately, the choice comes down to which tool provides better reporting and addresses the specific issues you are concerned with. While there may be some overlap between the two, each tool may have minor differences in how they catalog and report issues.

Answer №2

Generally speaking:

tserver is a specialized service that operates TypeScript in the background and can handle compilation commands effectively. TypeScript, while not primarily a linter, serves as a compiler that excels at detecting type errors and pinpointing certain code issues. eslint, on the other hand, functions as a JavaScript linter dedicated to identifying issues within your code.

In practice, it is common to utilize TypeScript for addressing type errors specifically, while relying on eslint to flag any additional potential problems or enforce stylistic conventions in your codebase.
