CorDapp developer project planning

When planning to develop a CorDapp, consider the following factors:

• CorDapp development requirements
• CorDapp development and testing environments

Prerequisites for CorDapp development

There are a number of pre-requisites for CorDapp development.

• You must use the Java 17 JVM, version 17.0.9 and onwards are supported, but version 18 and later is not supported.
• Gradle 7.6.4
• An IDE of your choice. We use IntelliJ because it has strong Kotlin support.
• Git, for running example projects.
• The following operating systems are supported in development:

CorDapp testing and performance

When developing CorDapps, you should have three initial environments:

1. A development environment.
2. An initial testing environment.
3. A more fully-featured performance and verification testing environment.

Development environment

A CorDapp development environment can be hosted on a typical development machine, running Windows, Linux, or macOS.

For more information on developing CorDapps, see developing CorDapps.

Testing environment

While in development a CorDapp should be regularly tested using a local testing environment to ensure the flows CorDapp is delivering the intended function. Nodes can be created locally using the network bootstrapper tool.

A local testing environment should use nodes in devMode with no other network components.

For more information on testing CorDapps, see debugging and testing.
