⚙️ Usage

Basic usage:

npx vue-mess-detector analyze [path]

Options:

| Option | Description | Default | Example | | ----------- | ------------------------------------------------------- | ------- | ------------------------------------------------------ | | [path] | Specify directory or file to analyze | ./src | ./src/components/AppHeader.vue | | --exclude | Exclude directories or files (comma-separated) | None | --exclude=components,Gauranga.vue | | --apply | Apply only specific rulesets or rules (comma-separated) | All rules | --apply=vue-essential,magicNumbers | | --ignore | Ignore only specific rulesets or rules (comma-separated) | - | --ignore=vue-caution,functionSize | | --group | Group results by file or rule | rule | --group=file | | --order | Order results (asc or desc) | asc | --order=desc | | --level | Show only specific level (error or warning) | Both | --level=error | | --output | Output format text or table or json | text | --output=table |

If you want to store your flags in a configuration file, you can create a vue-mess-detector.json file in the root of your project with the following content:

{
  "apply": "vue-strong,rrd",
  "level": "error"
}

Then you can run the command without flags:

npx vue-mess-detector analyze

All flags will be read from the configuration file. All missing flags will be set to their default values except if you provide them as flags in the command line.

📊 Example output

Without --group flag (default behavior is to group per rule) ⬇️

With --group=file flag ⬇️

🧾 Output explanation

Group by Rule: In this view, the first line is highlighted in blue, representing the rule being evaluated. Following this, you'll see blocks of information structured as follows: file path, description, and message.

Group by File: In this view, the first line displays the file path being evaluated. Below this, you'll see blocks of information with the following structure: rule, description, and message.

• Rule: The blue line that defines the specific rule being evaluated.
• File: Shows the path to the file where the rule is applied.
• Description: A concise explanation of the rule, often accompanied by a link to relevant documentation for further details.
• Message: Indicates the line of code where the rule was violated.

[!IMPORTANT] Yellow messages are warnings, suggesting best practices, while red messages highlight errors that must be corrected.

📈 Code Health

According to the number of errors and warnings, and the lines of code in your project, we calculate a health score for your project.

The code health is:

• low if the score is under 75%
• medium if the score is between 75% and 85%
• ok if the score is between 86% and 95%
• good if the score is above 95%
