Server Setup

This document explains how to start Lowcoder server locally.

System Prerequisites

Java - OpenJDK 17 Maven - Version 3+ (preferably 3.8+)

MongoDB

If you don't have an available MongoDB, you can start a local MongoDB service with docker:

docker run -d  --name lowcoder-mongodb -p 27017:27017 -e MONGO_INITDB_DATABASE=lowcoder mongo

Configure the MongoDB connection URI in the application-lowcoder.yml

Redis

If you don't have an available MongoDB, you can start a local Redis service with docker:

docker run -d --name lowcoder-redis -p 6379:6379 redis

Configure the Redis connection URI in the application-lowcoder.yml

Build and start the Lowcoder server jar

1. Clone Lowcoder repository
2. Next, execute the following commands in sequence

cd server
mvn clean package
java -Dpf4j.mode=development -Dspring.profiles.active=lowcoder -Dpf4j.pluginsDir=lowcoder-plugins -jar lowcoder-server/target/lowcoder-server-1.0-SNAPSHOT.jar

Now, you can check the status of the service by visiting http://localhost:8080 through your browser. By default, you should see an HTTP 404 error.

Start with IntelliJ IDEA

Configure the Run/Debug configuration as shown in the screenshot below, the version used in the screenshot is IntelliJ IDEA 2021.3.2 (Community Edition):

JDK version	Java 17
-cp	lowcoder-server
VM options	-Dpf4j.mode=development -Dpf4j.pluginsDir=lowcoder-plugins -Dspring.profiles.active=lowcoder -XX:+AllowRedefinitionToAddDeleteMethods --add-opens java.base/java.nio=ALL-UNNAMED
Main class	com.lowcoder.api.ServerApplication

Next, execute the following commands in sequence

cd server
mvn clean package

After Maven package runs successfully, you can start the Lowcoder server with IntelliJ IDEA.
