Infonotion Low-code platform proof-of-concept (crude start for a low-code environment)

Installation

Needed:

• Neo4j 3.5.1, with apoc 3.5.0.11-all
• Php 7.3.6
• Composer 1.10.6

Preparations

• Install Php and make it findable in your repo folder

• Install Neo4j 3.5.1

• Install the apoc library (put the .jar in the neo4j/plugins folder)

• Start Neo4j

• Open the Neo4j Browser - http://localhost:7474/browser/

• Set the admin user (neo4j) password to "test" with the following command in the Neo4j Browser:

    :server change-password
  

Preparations for the code

• Clone the repo to a folder
• Open a command-line window in the folder of the cloned repo
• Build the webapp (type composer install
• Run the webapp (type php bin/console server:run)

Setting up the Database contents

• Open the Neo4j browser
• Execute:

CALL apoc.cypher.runFile("in_new_db.cypher")

Open the application

• Open http://127.0.0.1:8000/ (on Windows: using localhost:8000, can result in slowness due to the DNS resolve)

Formula 1 example database

The /examples folder contains a zip-file with a cypher-shell export of a F1 database. (The source of this data is: https://www.kaggle.com/rohanrao/formula-1-world-championship-1950-2020)

To add the example:

• Install Neo4j 3.5.1 (alernatively: make sure your existing 3.5.1 installation is completely empty)
• Install the apoc library (put the .jar in the neo4j/plugins folder)
• Unpack the zip-file to the import folder of your Neo4j
• ADD the following line to your conf/neo4j.conf (in the apoc section)

apoc.import.file.enabled=true

• Start Neo4j
• Go to: http://localhost:7474/browser/ and set the admin user (neo4j) password to "test"
• In the neo4j browser execute:

CALL apoc.cypher.runFile("in_F1_example.cypher")

• Open http://127.0.0.1:8000/
• You'll find a new F1 domain on the left-side.
• Try http://127.0.0.1:8000/frameN/View/F1/Season/empty This last is 100% configured and shows what can be done with the current ViewController

Questionnaire example database

The /examples folder contains a zip-file with a cypher-shell export of the Questionnaire database.

To add the example follow the steps of the F1 example, but with:

• for unpacking the zip use: "in_Questionnaire_example.zip"
• for the runFile command use: "in_Questionnaire_example.cypher"

Open http://127.0.0.1:8000/questionnaire/ListOfQuestions5edd01130cda05.66170200

Happy coding!
