npm has a revamped search experience with new, more transparent sorting options—Relevance, Downloads, Dependents, and Publish Date.
@dydxprotocol/v4-abacus
Advanced tools
Shared front-end and mobile logic written in Kotlin Multiplatform (https://kotlinlang.org/docs/multiplatform.html).
The library generates Swift framework for iOS, JVM library for Android, and Javascript code for Web.
https://www.oracle.com/java/technologies/downloads/#java11
Abacus uses Cocoapods to integrate with iOS project. The gradle configuration contains the steps needed to generate the .podspec file. Run
./gradlew podspec
to generate abacus.podspec. Configure your iOS project (https://github.com/dydxprotocol/native-ios) to import abacus.podspec.
You can also build the Abacus for iOS by running:
./gradlew assembleXCFramework
This generates the iOS framework in build/XCFrameworks folder.
Debugging on iOS directly from XCode is possible with a plugin (https://github.com/touchlab/xcode-kotlin)
Abacus builds and pushes the JVM target as a Github packagewith the followinng command:
./publish_android.sh
The Android app (https://github.com/dydxprotocol/native-android) has the Gradle build step to pull the Abacus target from GithubPackage.
Abacuas generates Javascript and Typescript files with the following command:
./gradlew assembleJsPackage
This outputs into build/distributions, and references the packages in the build/js directory.
Sample integration from a html page can be find in integration/Web.
You can export the build to a package locally with the following commands:
cd ./build/packages/js
npm pack
A tarball of the package should be created and you can install it to your project for local testing:
npm install PATH_TO_TARBALL
Abacus publishes using a library (https://github.com/mpetuska/npm-publish) with the following steps.
Shared code should have unit tests written in Kotlin residing in the src/CommonTest directory. Run the tests with the following command
./gradlew test
Integration tests can be written to call Abacus from non-Kotlin code (i.e., Swift, JS). Sample integration projects can be found in the integration directory.
./bump_version.sh
// create a state machine val stateMachine = PerpTradingStateMachine()
// send socket payload to the state machine and get the state // the param is the complete socket text val state = stateMachine.socket(payloadText)
// See src/commonTest/kotlin/exchange.dydx.abacus/PerpV3Tests.kt for testing code
Misc: Utils Protocols
state (top state) app -> AppStateMachine (contains network logic) modal -> StateMachine (contains business logic) changes -> Changes (utilities to identify which part of the state has changed)
processing:
step 1: processor (dynamic objects - dictionaries, list, not typed) markets orderbook trades funding asset (referenced from markets, such as icon, url etc) wallet (user info) account subaccount assetPositions openPositions orders fills transfers historicalPnl configs (from Veronica mostly)
step 2 calculator (dynamic) market (summary info) account (step 3) subaccount 3.1 calculate positon notionalTotal/valueTotal etc 3.2 calculate account equity etc, leverage, margin usage, buyingpower 3.3 calcualte position levereage, buyingpower account transformer (step 2) calculate postOrder and postAllOrderStates for account (total from trade input) and positions (size from trade input) input (step 1) trade input size (size, usdcSize, leverage) transfer input (not complete)
step 3 validator (from postOrder and postAllOrders states) trade transfer
step 4 output (structs, typed data) converts dynamic data to typed
step 5 responses Construct response object from output
test (supporting classes, mostly mocks) utils (just utilities)
AppStateMachine (app) StateMachine (payload and validation folder)
payload (test StateMachine payload and interaction) API -> expected state validation (separated from payload, to target validation tests)
app (test AppStateMachine IO requests)
