Package managers

Node projects are built (including postDeploy, preUndeploy) with either Yarn or npm. If a yarn.lock file is present in the root of your repository then Yarn is used for installing dependencies and running scripts. If not, then npm is used.

Java

It is currently recommended to create Connect applications using JavaScript or TypeScript. For more information about creating Connect applications with Java, contact the Connect support team.

Connect supports Java LTS release versions. Java 17 (LTS) is preferred and should be used to support Spring Boot 3:
