# NextGraph apps (Linux, MacOS, Windows, Android, iOS, web)

NextGraph native apps use the Tauri framework.

All the apps are using an embedded WebView that renders a Svelte app.

## Install

prerequisites: compile the local SDK

```
cd ../ng-sdk-js
wasm-pack build --target bundler
cd ../ng-app
```

```
cargo install tauri-cli --version "^2.0.0-alpha"
npm install -g pnpm
pnpm install
```

## Recommended IDE Setup

[VS Code](https://code.visualstudio.com/) + [Svelte](https://marketplace.visualstudio.com/items?itemName=svelte.svelte-vscode) + [Tauri](https://marketplace.visualstudio.com/items?itemName=tauri-apps.tauri-vscode) + [rust-analyzer](https://marketplace.visualstudio.com/items?itemName=rust-lang.rust-analyzer).

## Web

#### Dev

```
pnpm webdev
// then open http://localhost:1421/
```

#### Prod

```
pnpm webbuild
// then the application is available in dist-web folder
// can be served with:
cd dist-web ; python3 -m http.server
```

in order to build a self-contained html file, useful for offline use, do:

```
// uncomment line 14 of src/App.svelte: import * as api from "ng-sdk-js";
pnpm filebuild
// single file is available in dist-file/index.html
// the assets folder can be discarded

```

## Desktop

Install [all prerequisites](https://next--tauri.netlify.app/next/guides/getting-started/prerequisites/) for your dev platform.

to run the dev env :

```
## on macos
cargo tauri dev
## on linux
cargo tauri dev --target x86_64-unknown-linux-gnu
## on win
cargo tauri dev --target x86_64-pc-windows-msvc
```

to build the production app installer :

### MacOs

```
cargo tauri build
// the installer is then available in target/x86_64-apple-darwin/release/bundle/dmg/NextGraph_0.1.0_x64.dmg
// or if you just want the app, it is at target/x86_64-apple-darwin/release/bundle/macos/NextGraph.app
```

### Linux (Ubuntu 22.04)

```
cargo tauri build --target x86_64-unknown-linux-gnu
```

### Windows (7)

```
cargo tauri build --target x86_64-pc-windows-msvc
```

## Android

- [Install Android Studio](https://developer.android.com/studio)

- add the rust targets for android

```
rustup target add aarch64-linux-android armv7-linux-androideabi i686-linux-android x86_64-linux-android
```

- follow the steps for Android in the [Prerquisites guide of Tauri](https://next--tauri.netlify.app/next/guides/getting-started/prerequisites/)

Until I find out how to do this properly, if you are compiling the android app from a macos station, you need to override an env var. this is due to reqwest needing SSL support, and on linux and android it compiles it from source. apparently the compiler (cc-rs) doesn't know that when cross compiling to android targets, the tool ranlib is called llvm-ranlib (and not [target]-ranlib)

```
export RANLIB=/Users/[user]/Library/Android/sdk/ndk/[yourNDKversion]/toolchains/llvm/prebuilt/darwin-x86_64/bin/llvm-ranlib
```

to launch the dev app :

```
cargo tauri android dev
```

to build the production app :

```
cargo tauri android build
```

to debug the Svelte app, use Chrome :

- [chrome://inspect/#devices](chrome://inspect/#devices)
- install the [svelte extension](https://chrome.google.com/webstore/detail/svelte-devtools/ckolcbmkjpjmangdbmnkpjigpkddpogn)

## iOS

First, make sure Xcode is properly installed. then :

```
rustup target add aarch64-apple-ios x86_64-apple-ios aarch64-apple-ios-sim
```

to launch the dev app :

```
cargo tauri ios dev
```

to build the production app :

```
cargo tauri ios build

```
