Jinsi ya Kuweka Project Structure ya App (React Native / Flutter)

Hii blog post inaeleza jinsi ya kupanga project structure ya app yako kwa usahihi kabla ya kuanza development. Inatumika kwa React Native na Flutter, ikiwa na maelezo mafupi, mfano wa folder structure, na best practices.

1. Utangulizi

Moja ya makosa makubwa kwa developers ni kuanza kutengeneza app bila kupanga folders vizuri.
Ukiacha project bila mpangilio:

Code inakuwa ngumu kusoma

Bugs zinakuwa nyingi

Scaling inakuwa ngumu

Developers wengine hawaelewi project

Kwa hiyo, project structure nzuri ni msingi muhimu wa app yoyote.

2. Project Structure kwa React Native

React Native inatumia JavaScript/TypeScript, hivyo structure nzuri inaonekana kama hii:

project/
│── src/
│ ├── assets/
│ │ ├── images/
│ │ └── icons/
│ ├── components/
│ ├── screens/
│ ├── navigation/
│ ├── services/
│ ├── hooks/
│ ├── context/
│ ├── utils/
│ └── config/
│
├── android/
├── ios/
├── index.js
├── package.json
└── app.json

Maelezo ya Kila Folder
Folder Kazi Yake
assets/ Kuhifadhi picha, icons, fonts
components/ Components ndogo kama buttons, cards, inputs
screens/ Pages kuu kama Login, Home, Settings
navigation/ React Navigation files
services/ API calls (axios, fetch)
context/ Global state (Context API)
hooks/ Custom hooks (useAuth, useFetch)
utils/ Helpers, constants, formatters
config/ App config, theme, environment variables
Mfano wa Basic React Native Component
import React from 'react';
import { View, Text } from 'react-native';

export default function HomeScreen() {
return (
<View>
<Text>Karibu kwenye Home Screen</Text>
</View>
);
}

3. Project Structure kwa Flutter

Flutter hutumia Dart, na structure nzuri ni kama hii:

lib/
│── main.dart
│── src/
│ ├── screens/
│ ├── widgets/
│ ├── models/
│ ├── providers/
│ ├── services/
│ ├── utils/
│ ├── theme/
│ └── routes/
assets/
│── images/
│── icons/
pubspec.yaml

Maelezo ya Kila Folder
Folder Kazi Yake
screens/ Pages za app
widgets/ Reusable UI widgets
models/ Data models (user.dart, product.dart)
providers/ State management (Provider, Riverpod, Bloc)
services/ API calls, database helpers
utils/ Helpers, constants
theme/ Colors, fonts, theme styles
routes/ App routing
Mfano wa Basic Flutter Screen
import 'package:flutter/material.dart';

class HomeScreen extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(title: Text("Karibu Home")),
body: Center(child: Text("Home Screen")),
);
}
}

4. Best Practices za Project Structure

✔️ Tumia separation of concerns — kila file lifanye kazi moja
✔️ Tumia meaningful names — usiite file test1.js
✔️ Tumia reusable components/widgets
✔️ Epuka kuweka code nyingi kwenye file moja
✔️ Panga assets mapema
✔️ Andika documentation (README.md)

5. Jinsi ya Kujua Structure Iko Sawa

Maswali ya kujiuliza:

Naweza kumpa developer mpya project hii akaelewa ndani ya dakika 5?

Naweza kuipata screen yoyote kwa urahisi?

Kila file lina kazi moja maalum?

Component/Widget ninayohitaji nitaipata wapi?

Kama majibu yote ni “Ndiyo”, structure yako iko vizuri.

6. Hitimisho

Kupanga project structure kabla ya kuanza coding kunasaidia:

Kupunguza makosa

Kuongeza speed ya development

Kujenga app scalable

Kuweka team ifanye kazi kwa urahisi

React Native na Flutter zote zinahitaji foundation nzuri ili kujenga app yenye ubora wa juu.
