remark-lint-no-empty-image-alt-text

remark-lint-no-empty-image-alt-text

This remark-lint rule is created to check if all images have alt text or not. This will help to get standard accessibility for images.

<!-- Invalid -->

![](<image-path>)

<!-- Valid -->

![alt text](<image-path>)

Using the rule

With remark

Let’s say example.js looks as follows:

var report = require('vfile-reporter')
var remark = require('remark')
var remarkLint = require('remark-lint');
var imageAltText = require('remark-lint-no-empty-image-alt-text')

var file = remark()
            .use(remarkLint)
            .use(imageAltText)
            .processSync('![](./media/example.png)')

console.log(report(file))

Now, running node example.js yields:

  1:1-1:25  warning  Missing alt text for image!  no-empty-image-alt-text  remark-lint

⚠ 1 warning

Via .remarkrc

npm install -g remark-cli
npm install remark-lint remark-lint-no-empty-image-alt-text

Then, set up your .remarkrc:

{
  "plugins": [
    "lint",
    "lint-no-empty-image-alt-text"
  ]
}

Now you can use the following command to run the lint:

remark xxx.md

Via CLI

npm install -g remark-cli
npm install remark-lint remark-lint-no-empty-image-alt-text
remark -u lint -u lint-no-empty-image-alt-text xxx.md
