README

Teleop a Viam Rover using the Viam TypeScript SDK. Follow the instruction at Try Viam to connect to a remote Rover for free.

To connect to your robot, create a .env file in the project's root directory that has the following values, replacing the square brackets and their contents. You can get this information from the TypeScript code sample in your robot's control panel.

ROBOT_SECRET=[secret]
HOST=[host]
SIGNALING_ADDRESS=[address]
BASE_NAME=[base anem]
ICE_SERVER=[server]

For detailed information on running RedwoodJS projects, see the information below, but the simplest way to get started is just to run the following commands from the project's root directory

yarn
yarn rw dev

The app will be available at localhost:8910. It will attempt to connect to your Rover automatically, and after it does, the forward, backward, spin left and spin right buttons will function. The easiest way to use the app is to open the your robot's control panel in one window, and tap the arrow keys in redrover in another window off to the side

To build more functionality, the best place to start is by modifying src/pages/TeleopPage/TeleopPage.txt - you don't have to know much about RedwoodJS to do so, it's just TypeScript React code.

RedwoodJS Information

Welcome to RedwoodJS!

Prerequisites

• Redwood requires Node.js (>=14.19.x <=16.x) and Yarn (>=1.15)
• Are you on Windows? For best results, follow our Windows development setup guide

Start by installing dependencies:

yarn install

Then change into that directory and start the development server:

cd my-redwood-project
yarn redwood dev

Your browser should automatically open to http://localhost:8910 where you'll see the Welcome Page, which links out to a ton of great resources.

The Redwood CLI

Congratulations on running your first Redwood CLI command! From dev to deploy, the CLI is with you the whole way. And there's quite a few commands at your disposal:

yarn redwood --help

For all the details, see the CLI reference.

Prisma and the database

Redwood wouldn't be a full-stack framework without a database. It all starts with the schema. Open the schema.prisma file in api/db and replace the UserExample model with the following Post model:

model Post {
  id        Int      @id @default(autoincrement())
  title     String
  body      String
  createdAt DateTime @default(now())
}

Redwood uses Prisma, a next-gen Node.js and TypeScript ORM, to talk to the database. Prisma's schema offers a declarative way of defining your app's data models. And Prisma Migrate uses that schema to make database migrations hassle-free:

yarn rw prisma migrate dev

# ...

? Enter a name for the new migration: › create posts

rw is short for redwood

You'll be prompted for the name of your migration. create posts will do.

Now let's generate everything we need to perform all the CRUD (Create, Retrieve, Update, Delete) actions on our Post model:

yarn redwood g scaffold post

Navigate to http://localhost:8910/posts/new, fill in the title and body, and click "Save":

Did we just create a post in the database? Yup! With yarn rw g scaffold <model>, Redwood created all the pages, components, and services necessary to perform all CRUD actions on our posts table.

Frontend first with Storybook

Don't know what your data models look like? That's more than ok—Redwood integrates Storybook so that you can work on design without worrying about data. Mockup, build, and verify your React components, even in complete isolation from the backend:

yarn rw storybook

Before you start, see if the CLI's setup ui command has your favorite styling library:

yarn rw setup ui --help

Testing with Jest

It'd be hard to scale from side project to startup without a few tests. Redwood fully integrates Jest with the front and the backends and makes it easy to keep your whole app covered by generating test files with all your components and services:

yarn rw test

To make the integration even more seamless, Redwood augments Jest with database scenarios and GraphQL mocking.

Ship it

Redwood is designed for both serverless deploy targets like Netlify and Vercel and serverful deploy targets like Render and AWS:

yarn rw setup deploy --help

Don't go live without auth! Lock down your front and backends with Redwood's built-in, database-backed authentication system (dbAuth), or integrate with nearly a dozen third party auth providers:

yarn rw setup auth --help
