| ## Typescript/Javascript API | ||
|
|
||
| This repository provides a Typscript / Javascript binding through the use of the `remote-api-plugin` in this repo. | ||
| The long term plan is to use zenoh [Zenoh written in Rust](https://github.com/eclipse-zenoh/zenoh) to target WASM. | ||
| In its current state, it is not possible to compile Zenoh (Rust) to target WASM, and will need to undergo a fair amount of refactoring before that can happen. | ||

|
|
||
| ## Building the Typescript project | ||
| ### Executing the `zenohd` with `zenoh-plugin-remote-api` plugin | ||
|
|
||
| 1. Make sure that the following utilities are available on your platform. | ||
| - [NPM](https://www.npmjs.com/package/npm) | ||
| - [yarn](https://classic.yarnpkg.com/lang/en/docs/install/#debian-stable) | ||
| - [Typescript](https://www.typescriptlang.org/download/) | ||
| The `zenohd` router and its plugins should be built with the same Zenoh sources, the same version of the Rust compiler, and with the | ||
| same set of features. This requirement exists because the router and plugins share common Rust structures, and Rust doesn't guarantee | ||
| ABI compatibility of the memory representation of these structures. | ||
|
|
||
| 2. Navigate to the directory `zenoh-ts` | ||
| Therefore one of these methods is recommended to ensure that plugin and router are compatible: | ||
|
|
||
| 3. Run the commands: | ||
| 1. Install the latest release of `zenohd` and `zenoh-plugin-remote-api` | ||
|
|
||
| ```bash | ||
| yarn install | ||
| # | ||
| yarn run build | ||
| ``` | ||
| Ubuntu: | ||
|
|
||
| ```sh | ||
| echo "deb [trusted=yes] https://download.eclipse.org/zenoh/debian-repo/ /" | sudo tee -a /etc/apt/sources.list.d/zenoh.list > /dev/null | ||
| sudo apt update | ||
| sudo apt install zenohd | ||
| sudo apt install zenoh-plugin-remote-api | ||
| ``` | ||
|
|
||
| Mac-OS: | ||
|
|
||
| ```sh | ||
| brew tap eclipse-zenoh/homebrew-zenoh | ||
| brew install zenoh | ||
| brew install zenoh-plugin-remote-api | ||
| ``` | ||
|
|
||
| ## Building the Rust Plugin | ||
| Run the installed zenoh router with example config | ||
|
|
||
| 1. Make sure that the following utilities are available on your platform. | ||
| - [Cargo + Rust Compiler](https://rustup.rs/) | ||
| ```sh | ||
| zenohd --config EXAMPLE_CONFIG.json5 | ||
| ``` | ||
|
|
||
| Expected output is like: | ||
|
|
||
| 2. Navigate to `zenoh-plugin-remote-api` | ||
| ```txt | ||
| zenohd: zenohd v1.0.3 built with rustc 1.75.0 (82e1608df 2023-12-21) | ||
| zenoh::net::runtime: Using ZID: f7bc54e0941036422ec08ebac6fbdb40 | ||
| zenoh::api::loader: Loading plugin "remote_api" | ||
| zenoh::api::loader: Starting plugin "remote_api" | ||
| zenoh::api::loader: Successfully started plugin remote_api from "/usr/lib/libzenoh_plugin_remote_api.so" | ||
| zenoh::api::loader: Finished loading plugins | ||
| zenoh::net::runtime::orchestrator: Zenoh can be reached at: tcp/.... | ||
| ``` | ||
|
|
||
| 3. Run `cargo build` | ||
| 1. Build both the plugin and the router from the sources: | ||
|
|
||
| ## **Examples of usage** | ||
| Build the plugin `zenoh-plugin-remote-api` | ||
|
|
||
| ### Running the Rust Plugin | ||
| ```sh | ||
| cargo build | ||
| ``` | ||
|
|
||
| Prerequisites: | ||
| - You have a zenoh router (`zenohd`) installed, and the `zenoh_plugin_remote_api` library file is available in `~/.zenoh/lib`. | ||
| Build and run the zenohd from the same sources which were used for the plugin. | ||
| The zenohd dependency is specified in the `[workspace.metadata.bin]` section in Cargo.toml which is processed by the 3rd party tool [cargo-run-bin](https://crates.io/crates/cargo-run-bin). | ||
|
|
||
| ### **Setup via a JSON5 configuration file** | ||
| ```sh | ||
| cargo install cargo-run-bin | ||
| cargo bin zenohd --config EXAMPLE_CONFIG.json5 | ||
| ``` | ||
|
|
||
| - Create a `zenoh.json5` configuration file containing for example: | ||
| ```json5 | ||
| { | ||
| plugins: { | ||
| // configuration of "storage_manager" plugin: | ||
| remote_api: { | ||
| "websocket_port": "10000", | ||
| // secure_websocket configuration is optional | ||
| "secure_websocket": { | ||
| "certificate_path" : "/path/to/certificate", | ||
| "private_key_path" : "/path/to/private_key" | ||
| } | ||
| } | ||
| // Optionally, add the REST plugin | ||
| rest: { http_port: 8000 } | ||
| } | ||
| } | ||
| ``` | ||
| - Run the zenoh router with: | ||
| `zenohd -c zenoh.json5` | ||
| Expected output is like: | ||
|
|
||
| ## Adding Typescript to your application | ||
| ```txt | ||
| zenohd: zenohd vc764bf9b built with rustc 1.75.0 (82e1608df 2023-12-21) | ||
| zenoh::net::runtime: Using ZID: bb3fb16628f57e92f92accf2f5c81511 | ||
| zenoh::api::loader: Loading plugin "remote_api" | ||
| zenoh::api::loader: Starting plugin "remote_api" | ||
| zenoh::api::loader: Successfully started plugin remote_api from "./target/debug\\zenoh_plugin_remote_api.dll" | ||
| zenoh::api::loader: Finished loading plugins | ||
| zenoh::net::runtime::orchestrator: Zenoh can be reached at: tcp/... | ||
| ``` | ||
|
|
||
| The TypeScript library can be install from the command line: | ||
| ### Building the library | ||
|
|
||
| `npm install @eclipse-zenoh/[email protected]` | ||
| 1. Make sure that the following utilities are available on your platform. | ||
|
|
||
| Or added via package.json | ||
| - [NPM](https://www.npmjs.com/package/npm) | ||
| - [yarn](https://classic.yarnpkg.com/lang/en/docs/install/#debian-stable) | ||
| - [Typescript](https://www.typescriptlang.org/download/) | ||
|
|
||
| `"@eclipse-zenoh/zenoh-ts": "0.0.8" ` | ||
| 2. Navigate to the directory `zenoh-ts` | ||
|
|
||
| 1. Run the commands: | ||
|
|
||
| ```sh | ||
| yarn install | ||
| yarn run build | ||
| ``` | ||
|
|
||
| Note: In order to add this library to your project you must log into the github npm repository, | ||
| please refer to this link for more information [Accessing github NPM](https://docs.github.com/en/packages/working-with-a-github-packages-registry/working-with-the-npm-registry#authenticating-with-a-personal-access-token) | ||
| ### Build and run the command line examples | ||
|
|
||
| This library is currently compatible with browsers, but not with NodeJS due to websocket library limitations. | ||
| To run the command line examples use the javascript runtime [deno](https://deno.com/) which is expected to be consistent with the browser. | ||
|
|
||
| [zenoh]: https://github.com/eclipse-zenoh/zenoh | ||
| 1. Install [deno](https://deno.com/) | ||
| 1. Navigate to the `zenoh-ts/examples/deno` directory | ||
| 1. Install the `zenoh-ts` library by running `yarn install` | ||
| 1. Run zenohd with the remote_api plugin, configured to websocket port 10000, as described above | ||
| 1. Run the examples by running `yarn example <PATH TO EXAMPLE>`, i.e. `yarn example src/z_sub.ts` | ||
|
|
||
| To run publisher and subscriber examples: | ||
|
|
||
| ```sh | ||
| yarn example src/pub.rs | ||
| ``` | ||
|
|
||
| ```sh | ||
| yarn example src/sub.rs | ||
| ``` | ||
|
|
||
| The subscriber should start to receive messages from publisher: | ||
|
|
||
| ```text | ||
| >> [Subscriber] Received PUT ('demo/example/zenoh-ts-pub': '[0] 122,101,110,111,104') | ||
| >> [Subscriber] Received PUT ('demo/example/zenoh-ts-pub': '[1] 122,101,110,111,104') | ||
| >> [Subscriber] Received PUT ('demo/example/zenoh-ts-pub': '[2] 122,101,110,111,104') | ||
| ``` | ||
|
|
||
| This will start an instance of Deno running the example. | ||
| The application will attempt to connect to a `websocket_port` : `10000` where the Remote API plugin is expected to be running. | ||
|
|
||
| ### Adding Typescript to your application | ||
|
|
||
| The latest version of zenoh-ts library can be installed from npm: | ||
|
|
||
| ```sh | ||
| npm install @eclipse-zenoh/zenoh-ts | ||
| ``` |
