Build Typeform-Connected Web Apps with Axios and CData Connect AI
Axios is a JavaScript library that allows developers to make HTTP requests to servers from a web browser or Node.js. When paired with CData Connect AI, you get access to live Typeform data for your web apps. This article shows how to connect to Typeform and build web apps in Axios with access to live Typeform data.
Connect to Typeform from Axios
To work with Typeform in Axios, we need to connect to Typeform from Connect AI, provide user access to the connection, and create a Workspace for the Typeform data.
Connect to Typeform from Connect AI
CData Connect AI uses a straightforward, point-and-click interface to connect to data sources.
- Log into Connect AI, click Sources, and then click Add Connection
- Select "Typeform" from the Add Connection panel
-
Enter the necessary authentication properties to connect to Typeform.
Start by setting the Profile connection property to the location of the TypeForm Profile on disk (e.g. C:\profiles\TypeForm.apip). Next, set the ProfileSettings connection property to the connection string for TypeForm (see below).
TypeForm API Profile Settings
Authentication to TypeForm uses the OAuth standard.
To authenticate to TypeForm, you must first register and configure an OAuth application with TypeForm here: https://admin.typeform.com/account#/section/tokens. Your app will be assigned a client ID and a client secret which can be set in the connection string. More information on setting up an OAuth application can be found at https://developer.typeform.com/get-started/.
Note that there are several different use scenarios which all require different redirect URIs:
- CData Desktop Applications: CData desktop applications (Sync, API Server, ArcESB) accept OAuth tokens at /src/oauthCallback.rst. The host and port is the same as the default port used by the application. For example, if you use http://localhost:8019/ to access CData Sync then the redirect URI will be http://localhost:8019/src/oauthCallback.rst.
- CData Cloud Applications: CData cloud applications are similar to their desktop counterparts. If you access Connect AI at https://1.2.3.4/ then you should use the redirect https://1.2.3.4/src/oauthCallback.rst.
- Desktop Application: When using a desktop application, the URI https://localhost:33333 is recommended.
- Web Application: When developing a web application using the driver, use your own URI here such as https://my-website.com/oauth.
After setting the following connection properties, you are ready to connect:
- AuthScheme: Set this to OAuth.
- InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to manage the process to obtain the OAuthAccessToken.
- OAuthClientId: Set this to the Client Id that is specified in your app settings.
- OAuthClientSecret: Set this to Client Secret that is specified in your app settings.
- CallbackURL: Set this to the Redirect URI you specified in your app settings.
- Click Save & Test
-
Navigate to the Permissions tab in the Add Typeform Connection page and update the User-based permissions.
Add a Personal Access Token
When connecting to Connect AI through the REST API, the OData API, or the Virtual SQL Server, a Personal Access Token (PAT) is used to authenticate the connection to Connect AI. It is best practice to create a separate PAT for each service to maintain granularity of access.
- Click on the Gear icon () at the top right of the Connect AI app to open the settings page.
- On the Settings page, go to the Access Tokens section and click Create PAT.
-
Give the PAT a name and click Create.
- The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.
Configure Typeform Endpoints for Axios
After connecting to Typeform, create a workspace for your desired table(s).
-
Navigate to the Workspaces page and click Add to create a new Workspace (or select an existing workspace).
- Click Add to add new assets to the Workspace.
-
Select the Typeform connection (e.g. API1) and click Next.
-
Select the table(s) you wish to work with and click Confirm.
- Make note of the OData Service URL for your workspace, e.g. https://cloud.cdata.com/api/odata/{workspace_name}
With the connection, PAT, and Workspace configured, you are ready to connect to Typeform data from Axios.
Connect to Typeform Data in Axios Workflows
To establish a connection from Axios to CData Connect AI using the OData protocol, follow these steps.
- Create a project directory for your web app. For example: ~/connect_cloud/
- Open a terminal, navigate the the project directory and initialize a node project using the command:
npm init -y - Install the Axios dependency in the project using the following command:
npm install axios In your project directory, create a file called server.js that contains the following code. Provide your CData Connect AI username (e.g. [email protected]) and PAT (the PAT you created in the prerequisites). You must also provide a query for your data, such as SELECT * FROM API1.SCHEMA.Tags.
server.js code
const axios = require('axios') const user = '[email protected]' const pat = '***********************************'; //Your API endpoint const url = 'https://cloud.cdata.com/api/odata/{workspace_name}'; //Your data to be sent in the POST request const data = { "query":"SELECT * FROM {workspace_name}.SCHEMA.Tags" }; axios.post(url, data, { auth: { username: user, password: pat } }) .then(response => { const rows = response.data.results[0].rows; const schema = response.data.results[0].schema; //Create an array of column names const columnNames = schema.map(col => col.columnName); //Loop through each row and log the column name with its value rows.forEach(row => { const rowObject = {}; row.forEach((value, index) => { const columnName = columnNames[index]; rowObject[columnName] = value; }); console.log(rowObject); }) }) .catch(error => { console.error('Error:', error); });- In the terminal, execute the following command to run the server:
The query results will appear:node server.js{ ID: 1, VALUE: -2 } { ID: 2, VALUE: 1 } { ID: 11, VALUE: null } { ID: 3, VALUE: 2 } { ID: 4, VALUE: 5 } ...
