Using the module

Here is a few examples of the db module being used

//create a database
createDatabase('mood-tracker');

//get all documents out of the database and set it to local state
const tempArray: object[] = [];

        getAllDocuments().then((results:any) => {
            results.map((result:any) => {
                const dataItem = {
                    date: result.date,
                    Anxiety: result.anxiety,
                    Depression: result.depression
                };
                tempArray.push(dataItem);
            });
            this.setState({data: tempArray});
        });
			
//save or update a new document to the database
saveScore = () => {
        const date = new Date();
        const dateString=date.getMonth()+1+'/'+date.getDate()+'/'+date.getFullYear();
        // if the document already exists update the score
        if(this.state.data.find(data=>data.date===dateString)){
            getDocById(dateString).then((result) => {
               updateDocument(result, 'depression', this.state.depressionSlider).then(this.loadGraphDataFromPouchDB);
               updateDocument(result, 'anxiety', this.state.anxietySlider).then(this.loadGraphDataFromPouchDB);
           });
        }
        // if no document exists create one
        else {
            saveDocument({
                _id: dateString,
                date: dateString,
                anxiety: this.state.anxietySlider,
                depression: this.state.depressionSlider
            });
