How to load data from Typeform to MongoDB

To transfer data, you first need to access Typeform's API. Log into your Typeform account, navigate to the "API & Webhooks" section, and generate a personal access token. This token will allow you to authenticate requests to Typeform's API and fetch the responses.

Ensure that you have `Node.js` and `npm` installed on your system, as you'll use JavaScript to write scripts for data transfer. Install the `axios` library for making HTTP requests and `mongodb` library for MongoDB interactions using the following command:
```
npm install axios mongodb
```

Use the Typeform API to fetch submission data. Write a JavaScript script using `axios` to make a GET request to the Typeform responses endpoint. Replace `YOUR_FORM_ID` and `YOUR_ACCESS_TOKEN` with your form's ID and your API access token, respectively:
```javascript
const axios = require('axios');

async function fetchData() {
try {
const response = await axios.get('https://api.typeform.com/forms/YOUR_FORM_ID/responses', {
headers: {
'Authorization': `Bearer YOUR_ACCESS_TOKEN`
}
});
return response.data.items;
} catch (error) {
console.error('Error fetching data from Typeform:', error);
throw error;
}
}
```

Typeform data is often nested or formatted in a way that's not directly suitable for MongoDB. Write a function to transform the response data into a format that matches your MongoDB schema. This might involve mapping fields or restructuring objects:
```javascript
function transformData(typeformData) {
return typeformData.map(item => ({
responseId: item.response_id,
answers: item.answers.reduce((acc, answer) => {
acc[answer.field.id] = answer.text || answer.number || answer.choice.label;
return acc;
}, {})
}));
}
```

Use the `mongodb` library to establish a connection to your MongoDB database. Replace `YOUR_MONGO_URI` with your MongoDB connection string:
```javascript
const { MongoClient } = require('mongodb');

async function connectToMongoDB() {
const client = new MongoClient('YOUR_MONGO_URI', { useNewUrlParser: true, useUnifiedTopology: true });
try {
await client.connect();
console.log('Connected to MongoDB');
return client;
} catch (error) {
console.error('Error connecting to MongoDB:', error);
throw error;
}
}
```

Once connected to MongoDB, insert the transformed data into the appropriate collection:
```javascript
async function insertDataIntoMongoDB(client, data) {
const database = client.db('YOUR_DATABASE_NAME');
const collection = database.collection('YOUR_COLLECTION_NAME');
try {
const result = await collection.insertMany(data);
console.log(`${result.insertedCount} documents were inserted`);
} catch (error) {
console.error('Error inserting data into MongoDB:', error);
throw error;
}
}
```

Combine all the functions into a main execution script. Fetch, transform, and insert the data:
```javascript
async function main() {
const client = await connectToMongoDB();
try {
const typeformData = await fetchData();
const transformedData = transformData(typeformData);
await insertDataIntoMongoDB(client, transformedData);
} finally {
await client.close();
console.log('Disconnected from MongoDB');
}
}

main().catch(console.error);
```
Run your script using Node.js:
```
node your_script_name.js
```

This guide provides a structured approach to moving data from Typeform to MongoDB using custom scripts. Adjust the code snippets to match your specific requirements and environment settings.
