|

## Why We Made Store
|
||||
|
||||
[](https://codecov.io/gh/dropbox/Store)
|
||||
- Modern software needs data representations to be fluid and always available.
|
||||
- Users expect their UI experience to never be compromised (blocked) by new data loads. Whether an
|
||||
application is social, news or business-to-business, users expect a seamless experience both
|
||||
online and offline.
|
||||
- International users expect minimal data downloads as many megabytes of downloaded data can quickly
|
||||
result in astronomical phone bills.
|
||||
|
||||
Store is a Kotlin library for loading data from remote and local sources.
|
||||
|
||||
### The Problems:
|
||||
|
||||
+ Modern software needs data representations to be fluid and always available.
|
||||
+ Users expect their UI experience to never be compromised (blocked) by new data loads. Whether an application is social, news or business-to-business, users expect a seamless experience both online and offline.
|
||||
+ International users expect minimal data downloads as many megabytes of downloaded data can quickly result in astronomical phone bills.
|
||||
|
||||
A Store is a class that simplifies fetching, sharing, storage, and retrieval of data in your application. A Store is similar to the [Repository pattern](https://msdn.microsoft.com/en-us/library/ff649690.aspx) while exposing an API built with [Coroutines](https://kotlinlang.org/docs/reference/coroutines-overview.html) that adheres to a unidirectional data flow.
|
||||
|
||||
Store provides a level of abstraction between UI elements and data operations.
|
||||
|
||||
### Overview
|
||||
|
||||
A Store is responsible for managing a particular data request. When you create an implementation of a Store, you provide it with a `Fetcher`, a function that defines how data will be fetched over network. You can also define how your Store will cache data in-memory and on-disk. Since Store returns your data as a `Flow`, threading is a breeze! Once a Store is built, it handles the logic around data flow, allowing your views to use the best data source and ensuring that the newest data is always available for later offline use.

Store leverages multiple request throttling to prevent excessive calls to the network and disk cache. By utilizing Store, you eliminate the possibility of flooding your network with the same request while adding two layers of caching (memory and disk) as well as ability to add disk as a source of truth where you can modify the disk directly without going through Store (works best with databases that can provide observables sources like [Jetpack Room](https://developer.android.com/jetpack/androidx/releases/room), [SQLDelight](https://github.com/cashapp/sqldelight) or [Realm](https://realm.io/products/realm-database/))

### How to include in your project
|
||||
|
||||
Artifacts are hosted on **Maven Central**.
|
||||
|
||||
###### Latest version:
|
||||
|
||||
```groovy
|
||||
def store_version = "4.0.7"
|
||||
```kotlin
|
||||
STORE_VERSION = "5.0.0-alpha03"
|
||||
```
|
||||
|
||||
###### Add the dependency to your `build.gradle`:
|
||||
### Android
|
||||
|
||||
```groovy
|
||||
implementation "org.mobilenativefoundation.store:store4:${store_version}"
|
||||
implementation "org.mobilenativefoundation.store:store5:$STORE_VERSION"
|
||||
```
|
||||
|
||||
###### Set the source & target compatibilities to `1.8`
|
||||
### Multiplatform (Common, JVM, Native, JS)
|
||||
|
||||
```groovy
|
||||
android {
|
||||
compileOptions {
|
||||
sourceCompatibility 1.8
|
||||
targetCompatibility 1.8
|
||||
}
|
||||
...
|

```kotlin

commonMain {

With the above setup you have:
|

|

+ In-memory caching for rotation
|
||||
+ Disk caching for when users are offline
|
||||
+ Throttling of API calls when parallel requests are made for the same resource

Store uses generic keys as identifiers for data. A key can be any value object that properly implements `toString()`, `equals()` and `hashCode()`. When your `Fetcher` function is called, it will be passed a particular `Key` value. Similarly, the key will be used as a primary identifier within caches (Make sure to have a proper `hashCode()`!!).

The first time you call to `suspend store.get(key)`, the response will be stored in an in-memory cache and in the sourceOfTruth, if provided.

### Inflight Debouncer
|
||||
|
||||
To prevent duplicate requests for the same data, Store offers an inflight debouncer. If the same request is made as a previous identical request that has not completed, the same response will be returned. This is useful for situations when your app needs to make many async calls for the same data at startup or when users are obsessively pulling to refresh. As an example, The New York Times news app asynchronously calls `ConfigStore.get()` from 12 different places on startup. The first call blocks while all others wait for the data to arrive. We have seen a dramatic decrease in the app's data usage after implementing this inflight logic.

### Disk as Cache
|

|
||||
Stores can enable disk caching by passing a `SourceOfTruth` into the builder. Whenever a new network request is made, the Store will first write to the disk cache and then read from the disk cache.

Cache
|
||||
===================
|
||||
# Cache
|
||||
|
||||
Store depends on a subset of Guava, we have extracted these parts into a shaded Cache artifact.
|
||||
Feel free to use Cache anytime you need an in memory cache implementation optimized for Android.
|
||||
Store depends on a subset of [Guava](https://github.com/google/guava).
|
||||
This is a shaded artifact that is Kotlin Multiplatform compatible.
|
||||
|
||||
## Usage
|
||||
|
||||
To use, first build a cache instance.
|
||||
|
||||
```java
|
||||
memCache = CacheBuilder.newBuilder()
|
||||
.maximumSize(getCacheSize())
|
||||
.expireAfterAccess(getCacheTTL(), TimeUnit.SECONDS)
|
||||
.build();
|
||||
```kotlin
|
||||
implementation("org.mobilenativefoundation.store:cache:${STORE_VERSION}")
|
||||
```
|
||||
|
||||
You can then use your cache as regular cache or one that knows how to load itself (with blocking) when empty
|
||||
```java
|
||||
memCache.get(key, new Callable<T>() {
|
||||
@Override
|
||||
public Observable<T> call() throws Exception {
|
||||
return getCachedValue(key);
|
||||
}
|
||||
});
|
||||
```
|
||||
## Implementation
|
||||
|
||||
Please refer to Guava's Cache documentation for additional features/configurations
|
||||
https://github.com/google/guava/wiki/CachesExplained
|
||||
### Model the key
|
||||
|
||||
```groovy
|
||||
implementation "org.mobilenativefoundation.store:store4:${store_version}"
|
||||
```kotlin
|
||||
data class Key(
|
||||
val id: String
|
||||
)
|
||||
```
|
||||
Please refer to the [Store Readme](https://github.com/dropbox/Store/blob/main/README.md#latest-version) for the latest version.
|
||||
|
||||
### Model the value
|
||||
|
||||
```kotlin
|
||||
data class Post(
|
||||
val title: String
|
||||
)
|
||||
```
|
||||
|
||||
### Build the cache

val cache = CacheBuilder<Key, Post>()
|
||||
.maximumSize(100)
|
||||
.expireAfterWrite(1.day)
|
||||
.build()
|

||||
* and once after loading completes). Much internal cache management is performed at the segment
|
||||
* granularity. For example, access queues and write queues are kept per segment when they are
|
||||
* required by the selected eviction algorithm. As such, when writing unit tests it is not
|
||||
* uncommon to specify {@code concurrencyLevel(1)} in order to achieve more deterministic eviction
|

* An object that measures elapsed time in nanoseconds. It is useful to measure

* System#nanoTime} for a few reasons:
|
||||
* <p>
|
||||
* <ul>
|
||||
* <li>An alternate time source can be substituted, for testing or performance
|
||||
* reasons.
|
||||
* <li>As documented by {@code nanoTime}, the value returned has no absolute
|
||||
* meaning, and can only be interpreted as relative to another timestamp
|
||||
* returned by {@code nanoTime} at a different time. {@code Stopwatch} is a
|
||||
* more effective abstraction because it exposes only these relative values,
|
||||
* not the absolute ones.
|
||||
* </ul>
|
||||
* <p>
|
||||
* <p>Basic usage:
|
||||
* <pre>
|
||||
* Stopwatch stopwatch = Stopwatch.{@link #createStarted createStarted}();
|
||||
* doSomething();
|
||||
* stopwatch.{@link #stop stop}(); // optional
|
||||
*
|
||||
* long millis = stopwatch.elapsed(MILLISECONDS);
|
||||
*
|
||||
* log.info("time: " + stopwatch); // formatted string like "12.3 ms"</pre>
|
||||
* <p>
|
||||
* <p>Stopwatch methods are not idempotent; it is an error to start or stop a
|
||||
* stopwatch that is already in the desired state.
|
||||
* <p>
|
||||
* <p>When testing code that uses this class, use
|
||||
* {@link #createUnstarted(Ticker)} or {@link #createStarted(Ticker)} to
|
||||
* supply a fake or mock ticker.
|
||||
* <!-- TODO(kevinb): restore the "such as" --> This allows you to
|
||||
* simulate any valid behavior of the stopwatch.
