lint

Basic

Currently an unstable command so you need add a flag.

Run on current directly.

$ deno lint --unstable

Run on a file.

$ deno lint --unstable server.ts
Checked 1 file

Ignore

If you have a build directory, you’ll want to ignore it. You must use = after --ignore as a space does not work. You can separate multiple values with commas.

$ deno lint --unstable --ignore=build

Linter in the docs.

deno_lint docs - provides searchable rules.

Rules

Rules and ignoring rules - from the CLI help:

List available rules:
  deno lint --unstable --rules

Ignore diagnostics on the next line by preceding it with an ignore comment and
rule name:
  // deno-lint-ignore no-explicit-any

  // deno-lint-ignore require-await no-empty

Names of rules to ignore must be specified after ignore comment.

Ignore linting a file by adding an ignore comment at the top of the file:
  // deno-lint-ignore-file
