 # Redeuce
+
+`redeuce` is a collection of tools that generates micro redux store.
+
+Let's take as an example a redux store designed as follow:
+
+```json
+{
+  "ui": {
+    "isLoading": false,
+    "filter": ""
+  },
+  "db": {
+    "users": [
+      { "id": 1, "firstname": "john", "lastname": "doe" },
+      { "id": 2, "firstname": "thi", "lastname": "tran" }
+    ],
+    "messages": [
+      { "mId": 1, "message": "hello", "senderId": 1 },
+      { "mId": 2, "message": "sup?", "senderId": 2 }
+    ]
+  }
+}
+```
+
+Redeuce will help you splitting this store into 4 easily manageable sub part.
+
+* `ui` that consist of two simple keys:
+  * `isLoading`
+  * `filter`
+* `db` that consists of two collection keys:
+  * `users`
+  * `messages`
+
+## simpleStore
+
+Let's first take a look at the simple keys: `isLoading` and `filter`.
+A `simpleStore` will generate a reducer and a single action-creator associated to set the value.
+
+```js
+// /store/ui.js
+import { combineReducers } from 'redux';
+import { simpleStore } from 'redeuce';
+
+// 'ui/isLoading' is a unique identifier for this store.
+// it can be anything, as long as it is unique.
+const { set: setIsLoading, reducer: isLoading } = simpleStore('ui/isLoading', {
+  defaultValue: true,
+});
+const { set: setFilter, reducer: filter } = simpleStore('ui/filter');
+
+// action creators
+export { setIsLoading, setFilter };
+// reducer creators
+export default combineReducers({
+  isLoading,
+  filter,
+});
+```
+
+From there, you have a reducer to use in your store and 2 action-creators to update the loading/ready keys in your store. No need to create action-types or switch cases in a reducer. `redeuce` generates all that for you.
+
+```js
+// /index.js
+import { createStore } from 'redux';
+import ui, { setIsLoading, setFilter } from './store/ui';
+
+const store = createStore({ ui });
+console.log(store.getState()); // { ui: { isLoading: true, filter: null }
+
+store.dispatch(setIsLoading(false));
+console.log(store.getState()); // { ui: { isLoading: false, filter: null }
+
+store.dispatch(setFilter('name'));
+console.log(store.getState()); // { ui: { isLoading: false, filter: 'name' }
+```
+
+## collectionStore
+
+A collection is an array of object that can be identified by a common key.
+That common key is configurable, but will be defaulted as `id`.
+
+```js
+// /store/db.js
+import { combineReducers } from 'redux';
+import { collectionStore } from 'redeuce';
+
+const { set: setUser, merge: mergeUsers, reducer: users } = collectionStore('db/users');
+const {
+  set: setMessage,
+  delete: deleteMessage,
+  mergeDeep: mergeDeepMessages,
+  reducer: messages,
+} = collectionStore('db/messages', { entityIdkeyName: 'mId' });
+
+// action creators
+export { setUser, mergeUsers, setMessage, deleteMessage, mergeDeepMessages };
+// reducer creators
+export default combineReducers({
+  users,
+  messages,
+});
+```
+
+We just created some powerful tools to manage our collections in a redux store:
+
+```js
+// /index.js
+import { createStore } from 'redux';
+import db,  setUser, mergeUsers, setMessage, deleteMessage, mergeDeepMessages } from './store/db';
+
+const store = createStore({ db });
+console.log(store.getState());
+/*
+{
+  db: { users: [], messages: [] },
+}
+*/
+
+store.dispatch(setUser({id: 1, name: 'john' }));
+console.log(store.getState());/*
+{
+  db: { users: [{id: 1, name: 'john' }], messages: [] },
+}
+*/
+
+store.dispatch(mergeUsers([{ id: 2, name: 'thi' }, {id: 3, name: 'Pedro' }]));
+console.log(store.getState());
+/*
+{
+  db: {
+    users: [
+      { id: 1, name: 'john' },
+      { id: 2, name: 'thi' },
+      { id: 3, name: 'Pedro' },
+    ],
+    messages: [] },
+}
+*/
+
+store.dispatch(setMessage([{ mid: 1, message: 'hello' }]));
+console.log(store.getState());
+/*
+{
+  db: {
+    users: [
+      { id: 1, name: 'john' },
+      { id: 2, name: 'thi' },
+      { id: 3, name: 'Pedro' },
+    ],
+    messages: [
+      { mid: 1, message: 'hello' },
+    ]
+  },
+}
+*/
+
+store.dispatch(mergeDeepMessages([{ mid: 1, user: 1 }, { mid: 2, message: 'world' }]));
+console.log(store.getState());
+/*
+{
+  db: {
+    users: [
+      { id: 1, name: 'john' },
+      { id: 2, name: 'thi' },
+      { id: 3, name: 'Pedro' },
+    ],
+    messages: [
+      { mid: 1, message: 'hello', user: 1 },
+      { mid: 2, message: 'world' },
+    ]
+  },
+}
+*/
+```
