Regression: {{! template-lint-enable require-button-type }} not working

In the world of web development, adhering to coding standards and best practices is crucial for maintaining a clean, efficient, and scalable codebase. One such practice is ensuring that buttons have a specified type attribute, which is a fundamental aspect of accessibility and usability. However, a recent regression in Ember Template Lint has made it challenging to enforce this rule, leading to inconsistencies in code quality. In this article, we will delve into the issue, explore the steps to reproduce it, and discuss potential solutions.

The require-button-type rule in Ember Template Lint is designed to ensure that buttons have a specified type attribute, such as button, submit, or reset. This rule is essential for maintaining accessibility and usability in web applications. However, a recent regression has made it difficult to enforce this rule, leading to inconsistent code quality.

To reproduce the issue, follow these steps:

Step 1: Configure the require-button-type rule to false in the config file

Open your ember-template-lint configuration file and set the require-button-type rule to false. This will disable the rule globally.

module.exports = {
  extends: ["recommended"],
  rules: {
    'require-button-type': false, // rather enable on forms only, than to clutter all buttons with type="button"
  },
}

Step 2: Enable the require-button-type rule locally in a file

Create a new file with a .hbs extension and add the following code:

<template>
  {{! template-lint-enable require-button-type }}
  <form>
     <button></button> 
  </form>
</template>

In this code, we are enabling the require-button-type rule locally using the {{! template-lint-enable require-button-type }} directive. However, despite enabling the rule, Ember Template Lint does not mark the button with an error.

The regression appears to have occurred in a recent release of Ember Template Lint. However, the exact release that introduced the issue is unclear. Further investigation is required to pinpoint the regression to a specific release.

To resolve the issue, we can explore the following potential solutions:

Solution 1: Disable the require-button-type rule globally

One possible solution is to disable the require-button-type rule globally by setting it to false in the ember-template-lint configuration file. This will ensure that the rule is not enforced, and the issue is resolved.

module.exports = {
  extends: ["recommended"],
  rules: {
    'require-button-type': false, // rather enable on forms only, than to clutter all buttons with type="button"
  },
}

Solution 2: Enable the require-button-type rule globally

Another possible solution is to enable the require-button-type rule globally by setting it to true in the ember-template-lint configuration file. This will ensure that the rule is enforced, and the issue is resolved.

module.exports = {
 : ["recommended"],
  rules: {
    'require-button-type': true, // rather enable on forms only, than to clutter all buttons with type="button"
  },
}

Solution 3: Use a custom rule

A third possible solution is to create a custom rule that overrides the require-button-type rule. This can be achieved by creating a new rule in the ember-template-lint configuration file.

module.exports = {
  extends: ["recommended"],
  rules: {
    'require-button-type': {
      enabled: true,
      message: 'Button type is required',
    },
  },
}

In conclusion, the regression in Ember Template Lint has made it challenging to enforce the require-button-type rule, leading to inconsistent code quality. However, by exploring the steps to reproduce the issue, analyzing the regression, and discussing potential solutions, we can resolve the issue and maintain a clean, efficient, and scalable codebase.

Based on our analysis, we recommend the following:

  • Disable the require-button-type rule globally to resolve the issue.
  • Create a custom rule that overrides the require-button-type rule to enforce the rule.
  • Use a linter plugin that provides more advanced features and customization options.

By following these recommendations, we can ensure that our codebase adheres to coding standards and best practices, and maintain a high level of code quality.
Regression: {{! template-lint-enable require-button-type }} not working - Q&A

In our previous article, we explored the regression in Ember Template Lint that made it challenging to enforce the require-button-type rule. In this article, we will provide a Q&A section to address common questions and concerns related to this issue.

Q: What is the require-button-type rule in Ember Template Lint?

A: The require-button-type rule in Ember Template Lint is designed to ensure that buttons have a specified type attribute, such as button, submit, or reset. This rule is essential for maintaining accessibility and usability in web applications.

Q: Why is the require-button-type rule not working?

A: The regression in Ember Template Lint has made it difficult to enforce the require-button-type rule. This issue is likely due to a recent change in the linter's configuration or a bug in the linter itself.

Q: How can I reproduce the issue?

A: To reproduce the issue, follow these steps:

  1. Configure the require-button-type rule to false in the config file.
  2. Enable the require-button-type rule locally in a file using the {{! template-lint-enable require-button-type }} directive.
  3. Verify that Ember Template Lint does not mark the button with an error.

Q: What are the potential solutions to resolve the issue?

A: There are several potential solutions to resolve the issue:

  1. Disable the require-button-type rule globally.
  2. Enable the require-button-type rule globally.
  3. Create a custom rule that overrides the require-button-type rule.

Q: How can I create a custom rule to override the require-button-type rule?

A: To create a custom rule, follow these steps:

  1. Open the ember-template-lint configuration file.
  2. Add a new rule to the rules object.
  3. Set the enabled property to true and the message property to a custom error message.

Example:

module.exports = {
  extends: ["recommended"],
  rules: {
    'require-button-type': {
      enabled: true,
      message: 'Button type is required',
    },
  },
}

Q: What are the benefits of creating a custom rule?

A: Creating a custom rule provides several benefits, including:

  1. Customization: You can tailor the rule to your specific needs and requirements.
  2. Flexibility: You can override the default behavior of the require-button-type rule.
  3. Consistency: You can ensure that your codebase adheres to a consistent coding standard.

Q: How can I ensure that my codebase adheres to a consistent coding standard?

A: To ensure that your codebase adheres to a consistent coding standard, follow these best practices:

  1. Use a linter plugin that provides advanced features and customization options.
  2. Create a custom rule to override the require-button-type rule.
  3. Regularly review and update your codebase to ensure that it meets the coding standard.

In conclusion, the regression in Ember Template Lint has made it challenging to enforce the require-type rule. However, by exploring the steps to reproduce the issue, analyzing the regression, and discussing potential solutions, we can resolve the issue and maintain a clean, efficient, and scalable codebase. By following the Q&A section, you can address common questions and concerns related to this issue and ensure that your codebase adheres to a consistent coding standard.
