deno check exclude field in deno.json
Use the top-level exclude field in deno.json to skip files or directories when running deno check. The exclude field applies to deno check along with other subcommands like deno fmt and deno lint. Example: {"exclude": ["dist/", "vendor/", "**/*.generated.ts"]}
deno compile include and exclude in deno.json
The --include and --exclude paths can be set declaratively in deno.json under the 'compile' section, so you don't have to repeat them on every deno compile invocation. CLI flags are merged with the config: --include and --exclude add to the lists in deno.json rather than replacing them.
deno compile include/exclude deno.json example
Example deno.json configuration: { "compile": { "include": ["names.csv", "data", "worker.ts"], "exclude": ["data/secrets", "**/*.test.ts"] } }
deno.json desktop configuration block
Most settings can be configured in the desktop block of deno.json instead of being passed on every build. The desktop block can contain: app (with name, identifier, and icons), backend, output, release, and errorReporting fields.
deno.json desktop configuration example
Example deno.json desktop configuration: { "desktop": { "app": { "name": "MyApp", "identifier": "com.example.myapp", "icons": { "macos": "./icons/icon.icns", "windows": "./icons/icon.ico", "linux": "./icons/icon.png" } }, "backend": "cef", "output": { "macos": "./dist/macos", "windows": "./dist/windows", "linux": "./dist/linux" }, "release": { "baseUrl": "https://updates.example.com" }, "errorReporting": { "url": "https://errors.example.com/report" } } }
deno.json fmt configuration options
The fmt block in deno.json supports the following configuration options: useTabs (boolean), lineWidth (number), indentWidth (number), semiColons (boolean), singleQuote (boolean), and proseWrap (string). Example: {"fmt": {"useTabs": false, "lineWidth": 80, "indentWidth": 2, "semiColons": true, "singleQuote": false, "proseWrap": "preserve"}}.
deno.json fmt include and exclude options
The fmt block in deno.json supports include and exclude options to specify which files to format. Example: {"fmt": {"include": ["src/"], "exclude": ["src/testdata/", "src/generated/**/*.ts"]}}.
deno.json lint rules configuration
In deno.json, configure linting rules under the 'lint' object with 'rules' containing: tags (array of rule sets like 'recommended' or 'fresh'), include (array of individual rule names to enable), and exclude (array of rule names to disable).
deno.json lint file inclusion/exclusion
In deno.json, specify files to lint using the 'lint' object with 'include' (array of directories/files to lint) and 'exclude' (array of patterns to exclude, supporting glob patterns like 'src/generated/**/*.ts').
Configure unstable flags in deno.json
Unstable features can be configured in deno.json using the 'unstable' array, with flag names having the '--unstable-' prefix removed. Example: { "unstable": ["sloppy-imports", "webgpu"] }
