ASAM OSI Types

ASAM OSI Types provides TypeScript type definitions for the Open Simulation Interface (OSI) specification. OSI facilitates the interoperability of simulation environments in automated driving and advanced driver-assistance systems (ADAS) development.

---

Features

• Comprehensive TypeScript type definitions for the OSI specification.
• Simplifies development by enabling static type checking in TypeScript.
• Maintains compatibility with the official OSI schema versions.
• Designed for use in simulation and modeling projects involving OSI.

---

Installation

Install the package using npm or yarn:

npm install asam-osi-types

or

yarn add asam-osi-types

---

Build and Scripts

Here are the available commands and scripts for working with the project:

Build

npm run build

or

yarn build

Compiles the TypeScript code into JavaScript. The compiled output is stored in the dist/ folder.

Setup

npm run setup

or

yarn setup

Installs the OSI dependencies

Generate

npm run generate

or

yarn generate

Generates protobuf files

Lint

npm run lint

or

yarn lint

Lints the project using ESLint to enforce consistent code style.

Test

npm run test

or

yarn test

Runs the test suite to ensure the code functions as expected.

Clean

npm run clean

or

yarn clean

Removes the build output (dist/) and cleans up the workspace.

Additional Commands

npm run format

or

yarn format

Formats the codebase using Prettier to maintain consistent styling.

Usage

Here’s how to use the provided type definitions in a TypeScript project:

import { OsiMessage } from "@lichtblick/asam-osi-types";

// Example: Define an OSI Message
const message: OsiMessage = {
  header: {
    timestamp: {
      seconds: 1627500000,
      nanos: 123456789,
    },
    frame_id: "example-frame",
  },
  content: {
    exampleField: "value",
  },
};

console.log(message);

API Documentation

Main Types

• OsiMessage: Represents the base message format in OSI.
• Header: Metadata for OSI messages, including timestamps and IDs.
• Timestamp: Specifies time information.

For detailed type definitions, explore the source files in the src folder.

Local Testing

To test the package locally, build the project and run the following command to create a symbolic link for the package

npm link

Create a local typescript test project with an index.ts file

mkdir test-project && cd $_ && touch index.ts

Initialize project

npm init -y

Link test project with the package

npm link asam-osi-types

Import types into the test-project

import * as types from "asam-osi-types";

Versioning

The versioning for the project is handeled automatically via the github actions CI/CD workflow, it will always reflect the current version of the OSI repository.

Local versioning can be applied to the project through the package.json file, but it will not be reflected in the npm package metadata since it is overwritten when publishing.
