ewa-mobile

Mobile/desktop EWA client built with Vue 3, Vite, Vant and Tauri 2.

The frontend uses generated TypeScript APIs from the Tauri backend. The backend exposes local and remote model resources through che-tauri, backed by che-orm and SQLite.

Stack

• Vue 3 with <script setup>.
• TypeScript strict mode.
• Vite.
• Vue Router with hash history.
• Vant mobile UI components.
• Tauri 2 Rust backend.
• SQLite via che-orm.
• Remote REST access and sync via che-tauri/reqwest.

Setup

Install frontend dependencies:

npm install

Run frontend dev server:

npm run dev

Run the Tauri app in development mode:

npm run tauri dev

Build frontend:

npm run build

Build Tauri app:

npm run tauri build

Backend Commands

Run backend checks:

cd src-tauri
cargo fmt
cargo check

Apply migrations:

cd src-tauri
cargo run --bin manage -- migrate

Generate TypeScript API from Rust metadata:

cd src-tauri
cargo run --bin manage -- generate-ts --out ../src/generated

Create and apply migrations for one app:

cd src-tauri
cargo run --bin manage -- makemigrations <app>
cargo run --bin manage -- migrate <app>

Backend App Modules

Installed modules are registered in src-tauri/src/apps/mod.rs:

• users
• frcapp
• projectapp
• personemanagment
• contractapp

Each module usually contains models.rs, serializers.rs, filters.rs, mod.rs, and optional migrations/.

Generated API

Generated files live in src/generated:

• api_client.ts
• api.ts
• models.ts

Do not edit generated files manually unless there is a specific reason. After changing backend models, serializers, filters, or resource registration, regenerate them:

cd src-tauri
cargo run --bin manage -- generate-ts --out ../src/generated

Frontend code should use generated APIs, for example:

import { taskApi } from "../../../generated/api";

Shared list/detail loading should prefer src/shared/composables/useModelApi.ts.

Tauri Commands

Important commands registered in src-tauri/src/lib.rs:

• che_api: generic model API dispatch used by generated clients.
• auth_login: login against remote API.
• auth_set_token: restore saved auth token into backend state.
• auth_logout: clear backend token.
• auth_status: backend auth status.
• current_employee: fetch current employee from remote API.
• sync_contracts: sync contracts and application files to local SQLite.
• load_application_file: load local file bytes or download from remote URL.

Configuration

• src-tauri/app.toml contains database and remote API settings.
• src-tauri/src/lib.rs currently creates AppConfig inline, so do not assume app.toml is always the runtime source of truth.
• src-tauri/ewa-mobile.sqlite is a local SQLite database artifact.
• Remote API URLs are environment-specific.

Validation

Frontend change:

npm run build

Backend change:

cd src-tauri
cargo fmt
cargo check

Backend metadata or generated API change:

cd src-tauri
cargo fmt
cargo check
cargo run --bin manage -- generate-ts --out ../src/generated
cd ..
npm run build

Developer Notes

• Keep frontend code TypeScript-strict and avoid unused locals/parameters.
• Keep model, serializer, filter, resource registration, migration and generated TS in sync.
• Prefer the management CLI for migrations.
• Avoid editing generated TypeScript and old migration files by hand.
• Avoid inspecting or modifying src-tauri/target and generated Android build artifacts unless needed.
