# Elements API The Elements language is a simple, yet powerful **templating language** for RapidWeaver Elements, it's often referred to as the Elements API. The Elements language allows third-party developers to create custom Elements that can be used within the RapidWeaver Elements layout engine. Element Dev Packs (.elementsdevpack) are a bundle of files, usually a mixture of HTML, JS, CSS, JSON, and images. The only thing you need to start building your own custom Elements is a copy of RapidWeaver Elements. Previous web development experience is recommend, but not required. ### Open Source Components 🛠️ The Core Components built into Elements are now open source 🎉 You can learn more about our [Open Source Core Components that power Elements here](https://docs.realmacsoftware.com/elements-docs/elements-language/dev-resources/open-source-components). You may also want to take a look at the associated [Build Tools](https://docs.realmacsoftware.com/elements-docs/elements-language/dev-resources/build-tools). We also offer a simpler collection of [example Element Components](https://github.com/realmacsoftware/RWElementDevPacks/tree/main) to help you get started. These simple component packs provide ready-to-use Components and configuration files you can explore, modify, and build upon to create your own custom Components for Elements.It’s the best place to learn by example and understand how a complete Dev Pack is structured. ### What's Required? The following is a list of suggested tools to make developing Elements easier. * A copy of [RapidWeaver Elements](https://realmacsoftware.com/rapidweaver/) (Required). * Text editor, we recommend [Visual Studio Code](https://code.visualstudio.com). * Our [Elements Syntax Highlighter](https://docs.realmacsoftware.com/elements-docs/elements-language/dev-resources/syntax-highlighting) for Visual Studio. * [SF Symbol app](https://developer.apple.com/sf-symbols/) for icon name reference. ### Distributing Elements Packs Dev Packs (.devpack) are for development only. They’re uncompiled and unencrypted, allowing live editing and real-time updates during development. **⚠️ Do not share or sell Dev Packs:** They’re not optimised for distribution and can cause performance issues if misused. ✅ If you want to share or monitise your Dev Packs, they **must be compiled into Element Packs** (.elementpack) via the Elements Platform. [Learn more about distributing Element Packs](https://docs.realmacsoftware.com/elements-docs/store/creators/addon-distribution). ### Developer Community We have a [Component Development area](https://forums.realmacsoftware.com/c/rapidweaver-elements/custom-components/56) on the [Elements Forum](https://forums.realmacsoftware.com/c/rapidweaver-elements/developer/58).
