Meveo

Meveo is a platform that allow to develop and execute enterprise back and front applications. Watch an introduction video

It allow you to create and deploy at runtime with fine grained security :

• Data model, putting part of your entities in RDBMS, Neo4j, Infinispan, Elastic search
• Business logic (functions in java, js, python with management of their dependencies)
• API (REST, websocket)
• Notifications (triggering emails, webhooks, custom function ..)
• Workflows
• Tests

Speeding up the conception of apps.

It is intended to be run by Wildfly 18 with full Jakarta EE stack under licence : AGPLv3.0

Frontend framework https://github.com/meveo-org/meveo-fronted.github.io

Security & Monitoring

• Security [Monitoring](./meveo-api/src/main/java/org/meveo/api/rest/monitoring/README.md

Clustering

Meveo can be deployed in a wildfly cluster to scale its capabilities. Infinispan cache can be replicated/distributed/scaterred among nodes. A JMS topic is used to publish events to the cluster nodes.

REST API Reference

On a started instance, go to /meveo/api/rest/swagger.json or /meveo/api/rest/swagger.yaml

Troubleshooting

When encountering persistence errors you might have to connect to the DB container then to postgres:

docker exec -it postgres bash
psql meveo meveo
meveo=#\d  //to list the tables
meveo=#drop table myentity;
meveo=#drop sequence myentity_seq;
meveo=#^Z  //ctrl+Z

Migration from versions previous to 7.0.0

• The simplest solution is to uninstall / re-install all the modules
• If the uninstall is not possible without data loss, move your git/Meveo/src/main/java folder to git/Meveo/facets/java
