when I run node app.js nothing happen

[grugna]

I followed the documentation, created the config file, but when I run "node app.js" nothing happen and the application doesn't start. Do you have any suggestion on what I am missing?

[birm]

Thank you for reaching out! Can you share your config files? The app is currently a little picky about those.

[grugna]

Sure! They are json so I can't attach them here, I will just copy and paste the content.

dataDescription.json [ { "name": "var_1", "datatype": "integer", "dataProvider": "data_SOURCE", "attributeType": ["filtering"] }, { "name": "var_2", "datatype": "integer", "dataProvider": "data_SOURCE", "attributeType": ["filtering"] }, { "name": "var_3", "datatype": "integer", "dataProvider": "data_SOURCE", "attributeType": ["visual", "filtering"] }, { "name": "var_5", "datatype": "integer", "dataProvider": "data_SOURCE", "attributeType": ["filtering"] }, { "name": "var_6", "datatype": "integer", "dataProvider": "data_SOURCE", "attributeType": ["filtering"] }, { "name": "var_7", "datatype": "integer", "dataProvider": "data_SOURCE", "attributeType": ["filtering"] }, { "name": "var_8", "datatype": "integer", "dataProvider": "data_SOURCE", "attributeType": ["filtering"] }, { "name": "var_9", "datatype": "integer", "dataProvider": "data_SOURCE", "attributeType": ["filtering"] }, { "name": "var_4", "datatype": "integer", "dataProvider": "data_SOURCE", "attributeType": ["visual", "filtering"] }, { "name": "var_10", "datatype": "integer", "dataProvider": "data_SOURCE", "attributeType": ["filtering"] }, { "name": "var_11", "datatype": "integer", "dataProvider": "data_SOURCE", "attributeType": ["filtering"] } ]

visualization.json `[ { "visualizationType": "dataTable", "attributes":[

    {"attributeName": "var_1"},
    {"attributeName": "var_2"},
    {"attributeName": "var_3"},
    {"attributeName": "var_4"}
    ],
    "heading": "HEADING",
    "subheading": ""
}

]`

@grugna can you also give me the head and, if you can, a record or two of your csv? Thank you.

@birm I attached a zip file with the 4 config files and a csv with header and 4/5 rows. I'm looking forward to hearing from you.

use enum as the datatype in dataDescription.json

[birm]

two kinds of changes are required; in dataDescription, change "name" to "attributeName". In dataSource.json, change "csv" to "csvFile".

Here are the two files after these modifications, noting that DATA_SOURCE.csv is in ./data/ in my env.

dataSource.json

    "dataSourceAlias": "DATA_SOURCE",
    "dataSources": [
        {
            "sourceName": "DATA_SOURCE",
            "sourceType": "csvFile",
            "options":{
                "path": "data/DATA_SOURCE.csv"
            },
            "dataAttributes": ["var_1","var_2","var_3","var_4","var_5","var_6","var_7","var_8","var_9","var_10","var_11","var_12","var_13","var_14","var_15"]
        }
    ]
}

Thank you! This solved the problem.
