⚠ BREAKING CHANGES

See migration guide for details.

• api: The ConfigFactory parameter to ConfigLoader (and its child classes StaticConfigLoader and FileSystemConfigLoader) has been removed. No replacement.

If you are using this you are probably better off implementing a fully custom loader later returning a ResolvedConfig.

• api: A new getContextualDocumentation replaces the now deprecated getRuleDocumentation method. The context parameter to getRuleDocumentation is now required and must not be omitted.

For rule authors this means you can now rely on the context parameter being set in the documentation callback.

For IDE integration and toolchain authors this means you should migrate to use getContextualDocumentation as soon as possible or if you are continuing to use getRuleDocumentation you are now required to pass the config and context field from the reported message.

• api: This change affect API users only, specifically API users directly using the Config class. Additionally when using the StaticConfigLoader no modules will be resolved using require(..) by default any longer. Instructions for running in a browser is also updated, see below.

To create a Config instance you must now pass in a Resolver (single or array):

+const resolvers = [ /* ... */ ];
-const config = new Config( /* ... */ );
+const config = new Config(resolvers, /* ... */ );

This applies to calls to Config.fromObject(..) as well.

The default resolvers for StaticConfigLoader is StaticResolver and for FileSystemConfigLoader is NodeJSResolver. Both can optionally take a new set of resolvers (including custom ones).

Each resolver will, in order, try to load things by name. For instance, when using the NodeJSResolver it uses require(..) to load new items.

• NodeJSResolver - uses require(..)
• StaticResolver - uses a predefined set of items.
• api: The HtmlValidate class now has a Promise based API where most methods return a promise. The old synchronous methods are renamed.

Either adapt to the new asynchronous API:

-const result = htmlvalidate.validateFile("my-awesome-file.html");
+const result = await htmlvalidate.validateFile("my-awesome-file.html");

or migrate to the synchronous API:

-const result = htmlvalidate.validateFile("my-awesome-file.html");
+const result = htmlvalidate.validateFileSync("my-awesome-file.html");

For unittesting with Jest it is recommended to make the entire test-case async:

-it("my awesome test", () => {
+it("my awesome test", async () => {
   const htmlvalidate = new HtmlValidate();
-  const report = htmlvalidate.validateString("...");
+  const report = await htmlvalidate.validateString("...");
   expect(report).toMatchCodeFrame();
});

• api: ConfigLoader must return ResolvedConfig. This change affects API users who implements custom configuration loaders.

In the simplest case this only requires to call Config.resolve():

-return config;
+return config.resolve();

A resolved configuration cannot further reference any new files to extend, plugins to load, etc.

• api: The TemplateExtractor class has been moved to the @html-validate/plugin-utils package. This change only affects API users who use the TemplateExtractor class, typically this is only used when writing plugins.
• config: Deprecated severity alias disabled removed. If you use this in your configuration you need to update it to off.

 {
   "rules": {
-    "my-awesome-rule": "disabled"
+    "my-awesome-rule": "off"
   }
 }

• rules: The void rule has been removed after being deprecated a long time, it is replaced with the separate void-content, void-style and no-self-closing rules.

• deps: minimum required jest version is v27

6.0.0 (2021-09-26)

⚠ BREAKING CHANGES

See migration guide for details.

• htmlvalidate: This change only affects API users, the CLI tool continues to work as before.

The default configuration loader has changed from FileSystemConfigLoader to StaticConfigLoader, i.e. the directory traversal looking for .htmlvalidate.json configuration files must now be explicitly enabled.

• event: ConfigReadyEvent passes ResolvedConfig instance instead of ConfigData
• meta: MetaElement.attribute has changed from string[] to MetaAttribute[] and both requiredAttributes and deprecatedAttributes has been merged into object. This only affects API usage, primarily custom rules accessing attribute metadata.See MIGRATION.md for details.

The old format is deprecated but is internally converted as to not break user configuration. For compatibility it will probably be around for quite a while but users should try to migrate as soon as possible.

Features

• bump required node version to 12.22 (80f3399)

5.0.0 (2021-06-27)

⚠ BREAKING CHANGES

• the library is now shipped as a hybrid CJS/ESM package. If you are simply consuming the CLI tool or one of the existing integrations this will not affect you.

For plugin developers and if you consume the API in any way the biggest change is that the distributed source is now bundled and you can no longer access individual files.

Typically something like:

-import foo from "html-validate/dist/foo";
+import { foo } from "html-validate"

Feel free to open an issue if some symbol you need isn't exported.

If your usage includes checking presence of rules use the ruleExists helper:

-try {
-  require("html-validate/dist/rules/attr-case");
-} catch (err) {
-  /* fallback */
-}
+import { ruleExists } from "html-validate";
+if (!ruleExists("attr-case")) {
+  /* fallback */
+}

4.0.0 (2020-11-07)

⚠ BREAKING CHANGES

• config: With this release any custom configuration files will no longer automatically extend html-validate:recommended.

The previous behaviour was to to always merge with the default configuration containing extends: ["html-validate:recommended"]. This is counter-intuitive when adding a blank {} .htmlvalidate.json configuration file (or a file with extends: []). The new behaviour is to not apply default configuration if another configuration is found.

To retain the previous behaviour you must ensure your configuration contains extends: ["html-validate:recommended"]. Users who have root: true are not affected. If unsure: test your configuration by deliberatly introducing and error and verify it is detected.

For CLI users: ensure your .htmlvalidate.json configuration files are updated.

For IDE integration users: ensure your .htmlvalidate.json configuration files are updated.

For CLI API users: same as with CLI the configuration loading has changed and all users must update their .htmlvalidate.json accordingly.

For HtmlValidate API users: you are most likely not affected, only if both of the following conditions are true you need to take care to ensure any .htmlvalidate.json is updated:

1. you are using validateFile or supply filenames to other validation functions.
2. you allow user-supplied configurations (or use them yourself) via .htmlvalidate.json (default unless root: true is set in the configuration object passed to new HtmlValidate(..))

The ConfigLoader API has also been updated and fromTarget may now return null if no configuration file was found.

• The build folder has been renamed to dist.

This affects API users only and in general should not be an issue unless importing files via full path. In that case replace import 'html-validate/build/...' with import 'html-validate/dist/... but in general those imports are discouraged.

Instead users should import only via import { ... } from "html-validate" and file an issue if an export is missing.

This does not affect the elements imports which is considered a safe to import as-is.

• fix cosmetic case of wcag/h37 rule.

0.22.0 (2019-02-24)

Breaking changes

• HtmlElement direct access to attr is replaced with attributes. The former was an key-value object and the latter is a flattened array of Attribute.

Features

• exposes Source and AttributeData in shim.
• HtmlElement will now store duplicated (or aliased) attributes. The biggest change this introduces is that classList will now contain a merged list of all classes. This is needed when combining a static class attribute with a dynamic one.
• DOM Attribute got two flags isStatic and isDynamic to easily tell if the value is static or dynamic.
• more verbose exception when a transformer fails. (fixes #37)
• allow processAttribute hook to yield multiple attributes, typically used when adding aliased attributes such as :class. By adding both the alias and the original the latter can be validated as well (e.g. no-dup-attr can trigger for multiple uses of :class). (fixes #36)
• allow setting hooks when using HtmlValidate.validateString, makes it easier to write tests which requires hooks, e.g. processing attributes.

Bugfixes

• [attr] selector now matches boolean attributes.
• attribute-boolean-style and no-dup-attr now handles when dynamic attributes is used to alias other attributes, e.g :required="foo" no longer triggers an boolean style and class=".." combined with :class=".." no longer triggers duplicate attributes. (fixes #35)
• attribute-allowed-values now ignores boolean attributes with dynamic values. (partially fixes #35)

0.21.0 (2019-02-17)

Breaking changes

0.18.0 (2019-01-10)

Features

• add support for dynamic attribute values, that is the value is marked as being set but has no known value. Rules are expected to assume the value exists and is valid. The primary usage for this is in combination with the parseAttribute hook, e.g :id="..." can yield attribute id with a dynamic value.
• add support for transformer hooks, currently the only hook is parseAttribute allowing the transformer to alter the attribute before any events are emitted, e.g. it can pick up the vuejs :id attribute and pass it as id to allow other rules to continue just as if id was typed.

Bugfixes

• fix ConfigLoader tests when running on windows.

0.17.0 (2019-01-09)

Breaking changes
