Node.js officially supports a new platform: what does this mean for developers?

The JavaScript ecosystem continues to evolve rapidly. Last week, the Node.js team announced official support for a new hardware-software platform. This event marks an important step in expanding the accessibility of server-side JavaScript, allowing developers to run their applications on devices that were previously unavailable for this technology. We are talking about support for the RISC-V architecture — an open instruction set gaining popularity in the world of embedded systems, IoT, and cloud computing.

Why is this important?

For a long time, Node.js was primarily focused on x86 and ARM architectures. However, with the growing interest in open hardware solutions and the emergence of powerful RISC-V processors (for example, from SiFive and StarFive), an urgent need arose to port the runtime. The new Node.js build for RISC-V allows:

Running server applications on inexpensive and energy-efficient single-board computers with RISC-V.
Using a unified technology stack for development both on traditional servers and on Internet of Things (IoT) devices.
Participating in the development of an open architecture, gaining access to modern JavaScript tools without being tied to commercial vendors.
Optimizing infrastructure costs by using cheaper processors without sacrificing performance for certain classes of tasks.

Technical details and installation

Support is implemented at the compilation level of V8 (JavaScript engine) for the riscv64 target architecture. In the current version (experimental support in Node.js 20+ and stable in Node.js 22), all major modules are available, including HTTP, file system (fs), and cryptography. However, it is worth noting that some Native Addons may require recompilation.

To install the new build, developers need to download the corresponding binary file from the official website or use the nvm version manager with the architecture specified:

nvm install --arch=riscv64 node

Prospects and impact on the community

Experts note that this step will strengthen Node.js's position in areas such as Edge Computing and Smart Home. Now JavaScript developers can create full-fledged microservices that will run directly on sensors, controllers, and routers. For the educational community, this opens new horizons: students will be able to learn server-side programming on affordable and open hardware.

Additionally, RISC-V support contributes to market diversification. If previously the choice of platform was often dictated by compatibility with Node.js, now engineers can confidently choose an architecture based on tasks rather than runtime limitations.

What's next?

The Node.js team is already working on improving performance on RISC-V and plans to include full support in LTS releases by the end of the year. Developers are recommended to test their projects on the QEMU emulator with RISC-V emulation or on real hardware to identify possible incompatibilities.
