Building an Employee Survey Dashboard with Supabase and N8N

Many companies use questionnaires to keep track of their employee’s health and general wellbeing. Because of the time and complexity involved in building one, many choose to go ahead with off-the-shelf solutions that may be quick to set up but have poor analytics tools. For example, the organization might be interested in knowing specifics about the use of the survey/questionnaires. For example (include one or two examples here) But there’s something better than off-the-shelf, and it can be built using Appsmith.

In this article, I will teach you how to build a custom employee survey dashboard to fit your specific requirements. We’ll achieve this by tying together the best open-source tools in the business to build powerful workflows.

We’re going to cover a lot, but specifically, you will learn how to:

  • Use Supabase as a data source
  • Use filters in DB queries
  • Display data in charts
  • Perform email automation with N8N

You can peek ahead to see the app we’ll be building here. Let’s get started!

Project set up

As mentioned earlier, we’ll be using Supabase as our storage DB. Signup for Supabase and create three tables; an employee, a question, and a responses table. You can seed the database with this dummy data

You should also go-ahead to set up N8N. You can signup for the cloud version or self-host it. Create a new workflow, and we’ll come back to it in a bit.

Lastly, signup for Appsmith and create a new app. Go to Datasources > Create New > PostgreSQL and fill the form to connect to your Supabase instance.

Awesome! With this, we have completed all the setup. Let’s begin writing queries.

How to use filters in DB queries

We need to write a query to get questions from the DB. Let’s call this query get_questions, and it should look like this:

SELECT * FROM public."questions";


With the returned data, we can build a question filter. Drag in a select widget and configure its Options property shown below.

The name of the widget has been updated to q_filter
{{
[{label: 'all', value: '%'}]
.concat(get_questions.data.map(q =>({label: q.question, value: q.id})))
}}


question filter

Similarly, go ahead to build a team filter. Name the select widget t_filter, and its Options property should be:

[
    {
    "label": "all",
    "value": "%"
  },
    {
    "label": "hr",
    "value": "hr"
  },
  {
    "label": "marketing",
    "value": "marketing"
  },
  {
    "label": "engineering",
    "value": "engineering"
  },
    {
    "label": "logistics",
    "value": "logistics"
  }
]


Using the filters we just built, we can write filtered queries i.e., to get employees based on the selected team and get responses based on the chosen question and team.

Create a new query for employees and update its name to get_employees. The query should look like this:

SELECT id AS employee, name, email, team FROM public."employees"
WHERE team LIKE "{{t_filter.selectedOptionValue}}";

Similarly, the get_responses query for responses should look like this:

SELECT r."completedAt", r.employee, r.response, r.comment, e.age, e.sex, e.team
FROM responses r
INNER JOIN employees e ON r.employee=e.id
WHERE
    r.question LIKE "{{q_filter.selectedOptionValue || '%'}}"
    AND e.team LIKE "{{t_filter.selectedOptionValue}}";


Using a table widget, you can display the employee completion status like so:

employee completion

And, here’s the snipped used for the Table Data property:

{{
    get_employees.data.map
      (e => _.omit({
        ...e,
        ...get_responses.data.find(r => r.employee === e.employee)

      }, ['sex', 'age', 'response', 'employee', 'comment'])
      )
}}


How to display data in charts

In the last section, we wrote a query to get responses for the selected question and team. Now, we’re going to focus on displaying the data in charts.

From the widgets tab, drag a chart widget into the canvas. We want this chart to display the aggregate number for responses for a particular rating level, i.e. 26 employees rated 5. So for the Series Data property on the chart widget, use the snippet below:

[
  {
    "x": "5",
    "y": {{get_responses.data.filter(r => r.response === 5).length}}
  },
  {
    "x": "4",
    "y": {{get_responses.data.filter(r => r.response === 4).length}}
  },
  {
    "x": "3",
    "y": {{get_responses.data.filter(r => r.response === 3).length}}
  },
  {
    "x": "2",
    "y": {{get_responses.data.filter(r => r.response === 2).length}}
  },
  {
    "x": "1",
    "y": {{get_responses.data.filter(r => r.response === 1).length}}
  }
]


And your chart should look like this:

responses chart

We can also display responses by gender. For this, we’ll need a sex filter. You know the drill, so go and make one. Here’s mine (named f_sex):

sex filter

And now, we can display the data using a chart widget set to a Pie Chart Chart Type. Here’s the snippet:


chart for responses by gender

For some extra credit, use the principles above to build a filtered chart to display responses by age group. Here’s mine:

chart by age group

How to perform email automation with N8N

In this section, we’re going to look at how to send out emails from the dashboard using N8N.

For employees who haven’t completed a survey questionnaire, we need a way to resend it to them via email. Let’s build an N8N workflow for this.

The workflow would consist of two nodes, a webhook that accepts post requests and the second being a Gmail node. Here’s a snapshot of the workflow:

n8n workflow

The Gmail node should be configured to send an email by setting the Resource to Message and the Operation to Send. The subject should contain a link to the questionnaire form, and the recipient email should be an expression that is evaluated the payload of the webhook as shown below:

email field

Going back to the dashboard, we can create a new API to trigger this workflow. Go to Datasources > Create New > Create New API and enter the URL of the N8N webhook. Give the request a name i.e. send_email, set the request type to POST, and the body would be the email of the employee selected from the table:

send email API

Now, going back to the table widget, we can create a custom column of Column Type Button. Configure this column to run the send_email API when it is clicked. Thus, clicking on the button for a particular employee would resend the questionnaire to that employee via email.

Wrap up

you did  it

Awesome! We’ve been able to build the employee survey dashboard. You can take a look at the app here https://app.appsmith.com/applications/61281a99695af65b46d75843/pages/61281a99695af65b46d75845

You can expand on this and add more features to the app. The floor is all yours! We’d love to see what you add next. By the way, give us a star any time you visit github.

Announcement

Today we're excited to announce the launch of Version Control with Git, so that developers can collaborate and version control their applications. This has been one of the most requested features from our community.

While low-code frameworks like Appsmith save a developer's time via easier application management, faster plugging in of data sources, and effortless creation of UI, there are still aspects of a developer's usual workflow that aren't native to low-code platforms.

Version Control with Git, enables us to take a big step towards that.

Here's a short video on how you can use Version Control with Git:

Version Control with Git Highlights

Version Control with Git allows multiple developers to add their work in a git branch, raise a pull request for code reviews, integrate with CI/CD pipelines so that their changes go live when their pull requests are approved, and provide a commit history to go back to a previous version if something were to go wrong. You can now also test a new addition to your app on a separate branch without breaking your deployed version.

You can connect to any popular version control tool of your liking: Github, Gitlab, Bitbucket, AWS Code Commit and more.

Furthermore, if you're a large organization using isolated environments for your production and test apps, you can now ensure that your applications can only be promoted to production via your CI/CD processes.

Version Control For All

Appsmith's Community Edition users will be able to connect unlimited public repos and up to 3 private repos.

In contrast, low-code frameworks in the market today either don't offer this functionality as part of their open source or free edition (and instead offer a simple auto-save), or push it deep into their most expensive pricing plans (like Retool).

Head over to our Version Control with Git documentation on how to set up version control with your favorite version control tools and get the most out of it.

Monthly Round-up

If you’ve followed Appsmith for a while, you know that we can do a lot in 30 days! I am here to give you all the deets; follow along!

Application Theming [Beta]

One of our most awaited features — App Theming — is now out! Style your pages and widgets using global controls. We've also made it easy to change the visual layout with a single click.

Note that while all apps support theming, changing the theme or customizing the theme may not update the app entirely for older apps. We’ve done this to prevent overriding any changes you may have already made while styling your widgets. (Note that, this is a beta feature at the moment, and we are going to be improving it in the coming weeks).


Theming automatically updates multiple properties, including fonts, colors, borders, shadows, etc. All these properties can be configured from the property pane globally. Read the complete documentation here.

Discard Changes/ Delete Branch on Version Control

Version Control with Git is well-loved by Appsmith users, especially when working with teams. We’ve enhanced this feature by adding another option other than ‘commit’ to make it more flexible. Now you can discard changes on the current branch and reload the earlier, committed application. Additionally, you can also delete the stale or unused branches.

Allowing Camera and Microphone on iFrame

Are you communicating to other websites from Appsmith? Our latest improvements will help you get the most out of it. All you have to do is use allow="camera; microphone" on the attributes to be able to access the camera/microphone on the iframe.

Making it easy for you on Windows using WSL

Have trouble setting up the Appsmith server on Windows? Don’t worry. We’ve worked on some documentation to help you contribute to Appsmith on Windows operating systems that use WSL; check it out here. Prerequisite MongoDB is included, along with detailed notes on building/running the code and how to set up your code editor.

Improvements

New Copy Paste Experience

Duplicating widgets on Appsmith is now easier with the new-copy-paste experience. Here’s a quick summary of how it works:

When the layout widget is selected:

  • If the mouse pointer is not on the layout widget, the widget is pasted inside the layout widget at the bottom of the canvas.
  • If the mouse pointer is on the layout widget, the pasted widget will be aligned top-left of the mouse pointer inside the layout widget.

If the non-layout widget is selected, no matter where the mouse pointer is, It is pasted below the non-layout widget, and the widgets are aligned horizontally.

If the mouse pointer is on a widget and no widgets are selected, widgets will be posted below and are horizontally aligned.

More Pages? View them all at once!

We’ve added a new option to resize the entity explorer page to view more pages at once. Just find the expander and extend it based on your comfort :)

Total Records and Page Count on Table Header

More love to the table widget; we’ve just added total record count and page count on the table header.

CleanShot 2022-05-25 at 15.34.35@2x.png
Better Way of Running JS Objects

We’ve revamped the way we run JS Objects from the JS Editor. Just put the cursor inside the function and hit the RUN button. The editor automatically identifies which function you’re working on; you can always use the shortcuts to make this easier!

Additionally, the page load functions can be configured from the Settings tab, just like how we do it from queries!

CleanShot 2022-05-25 at 15.40.46@2x.png
Added top-level isValid property to JSONForm

Currently, the JSONForm widget has an isValid property inside the fieldState for each field. However, there is no top-level property to check all fields at once. With this update, we added an isValid property which can be used to check if the current form is valid (passes all validation) or not.

CleanShot 2022-05-25 at 15.47.07@2x.png
Enhanced Map Widget

We’ve added a new property to the Map widget that lets us enable search location from Map without entering the coordinates. You can search directly on the map and display searched fields on other widgets without clicking on the Map widget.

CleanShot 2022-05-25 at 15.48.29@2x.png

Collaborations, Technical Content, Videos & Tutorials

Last month was hectic! We’ve published a new video on how you can generate PDFs from Appsmith using APITemplate; not just this, we’ve successfully hosted a couple of live sessions.

  • In this Video, Confidence, our Developer Advocate, show us how you can build a workflow to generate PDFs from Appsmith by consuming APIs from APITemplte.io.
  • Shams Mosowi from Rowy.io collaborated with us to demonstrate how we can build an expense management tool that employees can use to submit expenses for approval using Rowy as the backend.
  • Getting started with Version Control with Git on Appsmith? We’ve created a guide on how you can connect to a Git provider to version control Appsmith apps. Watch it here.

If you're curious about what we were up to, look no further and follow this link.

If you’re interested in using a database not listed on our website as an integration, please let us know about it by raising a PR on Github, and we will do our best to include it at the earliest.

If you’ve followed Appsmith for a while, you know that we can do a lot in 30 days!

I am here to give you all the deets; follow along!

Introducing Multiple Widget Reflow

We’ve received a lot of positive feedback on our new drag and drop experience. Users dig being able to resize widgets and move them around. This provides them with the ultimate freedom to build applications however they want without barriers that might get in the way :P

We’ve made this even more fun and powerful by adding a multiple widget reflow feature. With this, users should be able to move widgets and resize them even when they are grouped.

This also makes the drag and drop experience more performant in avoiding UI lags while moving widgets.

Readable Application URLs

All of you have been waiting for a much-requested feature, and today, it’s finally here! The application URL now has your app name as a slug, making it easier for you to share and find your Appsmith applications. This is available immediately for all the old applications and, of course, the newly created ones. Here’s a sample app URL.


https://app.appsmith.com/app/april-round-up/home-6266f76700cba01cd0301e20

To upgrade your old app URLs, please navigate the updates section from the bottom bar and hit update. Here’s the recording of how you can do it:

Product Updates

New Response View Switchers

We've added a new response view switcher feature that lets users easily switch between response formats on the fly; you'll be able to view them in different formats (JSON, Table, RAW) based purely on ease of choice. This feature will be available on all action types (APIs/Queries on a datasource).

Added Button Variants in Table Column Type

It’s super easy to set a column type to a button on Appsmith - just navigate to column properties and update the type to Button. To make your table button more extraordinary, we’ve added the variant property taking inspiration from our button widget; with this, you can update table button types to different variants available.

CleanShot 2022-04-26 at 01.05.56@2x.png
Smart Substitution Feature on Firestore Plugin

We’ve added a smart substitution feature to Firestore plugin methods (to dynamically perform type conversions on field values in a request body). The smart substitution will work the same way for REST API requests.

Currently, this feature only gets applied to the body section of Create, Set, Add or Update commands, as this is the only input field that expects a JSON input type. This can be toggled by navigating to the settings tab on datasource.

Added MultipartFormDataType variants for REST Datasource

We’ve added ​​MultipartFormDataType variants; with this, users can add an array as a value for multipart requests on REST APIs. It will handle every item in the list as a part of the multipart request. Here’s what an example body will look like:


--IpJ9ACFxVbhXlAQuIFccoJ0K0ttFS5PVyfX3
Content-Disposition: form-data; name="myArray"
Content-Type: text/plain;charset=UTF-8
Content-Length: 3

One
--IpJ9ACFxVbhXlAQuIFccoJ0K0ttFS5PVyfX3
Content-Disposition: form-data; name="myArray"
Content-Type: application/json
Content-Length: 1

2
--IpJ9ACFxVbhXlAQuIFccoJ0K0ttFS5PVyfX3
Content-Disposition: form-data; name="myArray"
Content-Type: application/json
Content-Length: 4


Enhanced Text Widget

When the truncating text option is enabled in a text widget, the scroll switch is no longer valid; as we truncate to fix this issue, we made the following changes.

We’ve added an overflow property option with the following configurations:

  • Scroll Contents - Enables scroll in the text widget
  • Truncate Text - Enables truncation in the text widget
  • No Overflow - No scroll or truncation
CleanShot 2022-05-02 at 16.39.07@2x.png
Added Support to MinIO in S3

You can now connect MinIO instances on Appsmith using the S3 plugin. This can be done when:

  • over the unsecured connection (HTTP)
  • when secured via a CA-signed certificate (HTTPS)

You can find this connecting in a dropdown from the S3 datasource.

Select Widget is now 50x Faster on Large Datasets

We’ve been listening to a few issues with the select widgets when large datasets are used. Previously, in the case of these large data sets, the Select widget took up to 5 seconds to render. The initial render is down to ~100ms once the options are available from the API call.

Our engineers tested this thoroughly by loading 1000 options from a mock API on a newly upgraded test widget :)

New Collaborations, Technical Content, Videos & Tutorials

Last month was crazy for us; we’ve published a blog post on how you can connect Stipe on Appsmith to manage your transactions; not just this, we’ve successfully hosted four live sessions.

  • We’ve created a small guide on how you can use JSON forms on Appsmith. This widget lets you build any kind of form with JSON dynamically. Learn how to use it here.
  • Stephen Tillman, one of our active community members, joined us to show how Appsmith helped him to build a great dashboard that lets him manage credit cards on Brex using BrexAPIs. Watch the recording here.
  • Pranav and I hosted the third How Do I Do X session, where we picked questions from the community to integrate with ZohoCRM and Stripe APIs. We’ve also talked about how you can use resetWidget and clearWidget functions on Appsmith to handle form actions. Watch the recording here.

What’s a Rich Text element?

asdsadasdsa

asdsadasdsa

The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.

sfdfsdfds

dsfdsfdsf

adfkaldf

The rich text element allows you to create and format

sadadasdasdas dsada sadas asd ad

Static and dynamic content editing

  1. vdfgdgd
  2. gjgjg

A rich text element can be used with static or dynamic content. For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!

How to customize formatting for each rich text

Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.
