What is the process for developing a personalized set of tslint rules?

I am looking to create a comprehensive TypeScript coding guideline that can be easily shared across various projects. Instead of repeatedly copying and pasting a tslint.json file, I aim to have a unified version to avoid any divergence issues.

My guideline will be based on tslint:recommended, and I have noticed that the tslint syntax allows for the use of extend. However, I am unsure about how to use it and how to structure such a package.

Is it sufficient for this project to consist solely of a tslint.json file, or do I need to export a module?

My ultimate goal is to host this package on an npm or Sinopia instance, but I am uncertain about the next steps to take.

Absolutely! It is possible to create a custom NPM module that houses your set of rules and reference it in the extends setting of a tslint.json file.

For instance, you can construct an NPM module named my-custom-rules with the following contents in the package.json:

{
    "name": "my-custom-rules",
    "version": "1.0.0",
    "main": "my-custom-rules.json"
}

Include a file called my-custom-rules.json as follows (ensure that the main property in the package.json points to this file):

{
    "extends": "tslint:recommended",
    "rules":
    {
        ...
    }
}

Once you have my-custom-rules installed in the node_modules directory, you can easily extend a tslint.json file with your custom rule set:

{
    "extends": "my-custom-rules"
}

More detailed information about sharable configurations can be found in this informative TSLint blog post.

If your rule set only includes configurations for existing rules, then you are good to go. However, if you plan to implement new custom rules, ensure to reference the directory where these rules are stored in the my-custom-rules.json file. For example, include a line like:

"rulesDirectory": "./custom-rules"

. The ./custom-rules directory should contain compiled versions of your custom rules in .js format.
