Thanks for contributing to Nest Middlewares! This document outlines the best practice for adding your own middleware of choice.

1. Duplicate the tpl folder and move it into src.
2. Rename tpl to the exact name of the middleware as it is on NPM. For example, for Helmet, use helmet, or for body-parser, use body-parser.
3. In package.json, rename the name property to @nest-middlewares/MIDDLEWARE_NAME, where MIDDLEWARE_NAME is the same name as the middleware on NPM. Also, be sure to change the name of Middleware in the description field of package.json.
4. npm install the types for your middleware in the root folder (for example, npm install --save-dev @types/helmet). Make sure they are saved to devDependencies of the root package.json.
5. cd into your newly created middleware folder, and npm install the package containing the middleware and save it to package.json (for example, npm install --save helmet).
6. In index.ts, change all the instances of "middleware" to what they should logically be named, maintaining capitalization. Check out CONTRIBUTING.md for clarification.
7. Write tests as necessary for your middleware.
8. Run sh ./scripts/build.sh and make sure that no errors arise.
9. Run lerna clean && lerna bootstrap and make sure no errors arise.
10. 🎉 Congratulations! You've made a middleware! File a pull request, and sit back and look at your great work.
