Hello everyone!
The Languages team at DFINITY is excited to introduce mo-dev, a flexible command-line tool which enables full-stack live reloading for your Motoko dapp or smart contract.
Here is a Medium post with a bit of background about live reloading and some tips for setting up mo-dev for a new or existing project:
We’ve also set up an online Gitpod demo so that you can try mo-dev directly in your browser!
mo-dev is designed to work seamlessly with Vite and other popular front-end dev servers, contributing the following live-reload capabilities:
- Deploying canisters to the local replica
- Generating language bindings
- Running unit tests (files ending with
.test.mo) - Executing commands
Get started by running npm install -g mo-dev (or downloading a standalone binary from the GitHub releases page). From there, run mo-dev --help to view all available features.
Since mo-dev is already being used in several internal DFINITY projects, check out the following GitHub repositories for real-world usage examples:
- Vite + React + Motoko starter project
- DFINITY developer experience feedback board (Vite)
- Motoko Playground (Create React App)
- Motoko base library (unit testing)
It’s also worth mentioning that the Motoko VS Code extension has a built-in UI for the mo-dev test runner:
As always, feedback is an important part of our development process! Please feel free to report a bug, suggest a feature, make a contribution, or even just leave a star on the project’s GitHub repository:
Looking forward to seeing what you create with this new live-reload workflow!
