TechDocs is Spotify’s homegrown docs-like-code solution built directly into Backstage. [Backstage](https://github.com/backstage/backstage) gives teams one front-end view for all their infrastructure tools, like Google Cloud Platform, Cloud Bigtable, CI pipelines, TensorFlow Extended, and others, all in a consistent, easy-to-use interface, or portal. It's open source software released by Spotify.

- Service catalog - It keeps track of ownership and metadata for all the software in your ecosystem. Backstage does this by putting metadata in YAML files stored together with your code. You process these files and then you can visualise the catalog in Backstage. This catalog enables your teams to manage and maintain the software they own, making the software discoverable.
51
+
- Software templates - This feature allows you to create templates or skeletons of code. These templates are published to GitHub.
52
+
- Plugins - Allow you to integrate third party tools or any kind of infrastructure into Backstage. They are open source and you can view a list [here](https://backstage.io/plugins).
53
+
- Techdocs - Yay, finally, why we are here. Techdocs is Spotify's homegrown docs like code solution. It allows the user to store documentation near the relevant code, thus allowing the docs to be easily discovered and maintained.

- The Techdocs reader, it fetches remotes pages, runs "transforms" against them, and renders them in a shadow DOM.

- The Transforms API takes in parameters from the reader component and returns a function which gets passed the DOM of the fetched page.

- Transformers API is a function that takes in parameters from the reader component and returns a function which gets passed the dom of the fetched page.
When you open a TechDocs site, a request is made. The TechDocs reader calls the TechDocs-backend with the entity id and the path of the current page. The response contains the static content. The static content contains HTML and CSS, and any JavaScript is removed for security reasons.
