This project provides a templated upload form for documents made up of any number of table objects. Documents are stored as JSONB within a Postgresql database, which can then be used to construct views on the data.

All old versions of documents are saved, and can be easily restored.

There is a flexible schema to define each table within the document, and a table can have either a fixed list of columns / rows or a flexble number provided by the user. handsontable is used to provide the table component.

Documents can also be exported / imported from excel spreadsheets using js-xlsx, where each table will be on a separate sheet in the document. The import is intelligent enough to notice row / column reorderings and reassign data.

Install the following server prerequisites:

sudo apt install \
    nginx \
    python3-venv python3-dev \
    postgresql libpq-dev

Install nodejs to complile the front-end:

# NB: We need at least node >= 6.9.0, so you may need:
sudo apt install -t stretch-backports nodejs npm

Create a .local-conf for your site configuration, see the top of install.sh for available options, and then create. For example:

cat <<EOF > .local-conf
SERVICE_MODE=production
SERVER_NAME=ffdb.*
APP_GA_KEY=UA-XXXXX-Y
EOF

Run make to compile:

make

Finally run install to create a systemd service and nginx configuration:

sudo ./install.sh

Download a document:

curl 'http://ffdb-host/api/doc/dlmtool/document_name''http://ffdb-host/api/doc/dlmtool/document_name'

Upload a document:

curl -v -X PUT -H "Content-Type: application/json" \
    -T file.json \
    'http://ffdb-host/api/doc/dlmtool/document_name'
