Vue.js

At FundsCorner, when we set out to pick up the front-end tech stack (around Dec 2017), we drove our decision based on the following considerations:

(1) We were clear that we will NOT have a hybrid app. We will start with Responsive Web & once there is traction, we will rollout our Android App. However, we wanted to ensure that the users have a consistent experience on both the Web & the App. So, the front-end framework must also have a material design component library which we can choose from.

(2) Before joining FundsCorner as a CTO, I had already worked with Angular. I enjoyed working with Angular, but I felt that I must choose something that will provide us with the fastest time from Concept to Reality.

(3) I am strong proponent of segregating HTML & JavaScript. I.e. I was not for writing or generating HTML through JavaScript. Because, this will mean that the Front-end developers I have to hire will always be very strong on JavaScript alongside HTML5 & CSS. I was looking for a Framework that was on JavaScript but not HEAVY on JavaScript.

(3) The first iteration of the web app was to be done by myself. But I was clear that when someone takes up the mantle, they will be able to come up the curve fast.

In the end, Vue.js and Vuetify satisfied all the above criteria with aplomb! When I did our first POC on Vue.js I could not believe that front-end development could be this fast. The documentation was par excellence and all the required essentials that come along with the Framework (viz. Routing, Store, Validations) etc. were available from the same community! It was also a breeze to integrate with other JavaScript libraries (such as Amazon Cognito).

By picking Vuetify, we were able to provide a consistent UI experience between our Web App and Native App, besides making the UI development ultra blazing fast!

In the end, we were able to rollout our Web App in record 6 weeks (that included the end to end Loan Origination flow, Loans management system & Customer engagement module). www.jeyabalaji.com

Heroku Docker GitHub Node.js hapi Vue.js AWS Lambda Amazon S3 PostgreSQL Knex.js Checkly is a fairly young company and we're still working hard to find the correct mix of product features, price and audience.

We are focussed on tech B2B, but I always wanted to serve solo developers too. So I decided to make a $7 plan.

Why $7? Simply put, it seems to be a sweet spot for tech companies: Heroku, Docker, Github, Appoptics (Librato) all offer $7 plans. They must have done a ton of research into this, so why not piggy back that and try it out.

Enough biz talk, onto tech. The challenges were:

• Slice of a portion of the functionality so a $7 plan is still profitable. We call this the "plan limits"
• Update API and back end services to handle and enforce plan limits.
• Update the UI to kindly state plan limits are in effect on some part of the UI.
• Update the pricing page to reflect all changes.
• Keep the actual processing backend, storage and API's as untouched as possible.

In essence, we went from strictly volume based pricing to value based pricing. Here come the technical steps & decisions we made to get there.

1. We updated our PostgreSQL schema so plans now have an array of "features". These are string constants that represent feature toggles.
2. The Vue.js frontend reads these from the vuex store on login.
3. Based on these values, the UI has simple v-if statements to either just show the feature or show a friendly "please upgrade" button.
4. The hapi API has a hook on each relevant API endpoint that checks whether a user's plan has the feature enabled, or not.

Side note: We offer 10 SMS messages per month on the developer plan. However, we were not actually counting how many people were sending. We had to update our alerting daemon (that runs on Heroku and triggers SMS messages via AWS SNS) to actually bump a counter.

What we build is basically feature-toggling based on plan features. It is very extensible for future additions. Our scheduling and storage backend that actually runs users' monitoring requests (AWS Lambda) and stores the results (S3 and Postgres) has no knowledge of all of this and remained unchanged.

Hope this helps anyone building out their SaaS and is in a similar situation.

We chose Vue.js at Codecov to replace a front end that was based mostly on server side rendered Python templates, and was getting fairly long in the tooth. The move to Vue.js allowed us to take a more component driven approach to our front end, providing greater flexibility and reuse when creating new pages and refactoring old ones. Another bonus was how easily we could integrate Axios with VueJS for making AJAX calls within Vue.js components and their associated vuex stores. We were also able to easily integrate Vue.js with the Jest testing framework, which allowed to provide test coverage for a front end where none previously existed.

The move to Vue.js has allowed us to be more agile in our front end development by further decoupling our front end from our back end. Additionally, by fully embracing a component-driven approach, we're able to more easily isolate and test functionality, leading to a more readible, maintainable, and extensible front end codebase.

Vue.js JavaScript vuex

If you run a SaaS, you probably want to show your users when they are almost running out of widgets. Or that they can get some cool feature on a more expensive plan.

Or, in other words, how can you be nice and commercial in dealing with plan limits?

We use Vue.js with Vuex for our front end, but the patterns and code examples here can be applied to any other SPA framework.

We implemented some very specific data structures in Vuex to make it easy for components to check what a user's status is with regard to plan limits and usage. This centralizes and encapsulates the knowledge about typical SaaS things in one place and leverages Vue's component system nicely. Read more in the dedicated blog post.

At FundsCorner, we are on a mission to enable fast accessible credit to India’s Kirana Stores. We are an early stage startup with an ultra small Engineering team. All the tech decisions we have made until now are based on our core philosophy: "Build usable products fast".

Based on the above fundamentals, we chose Python as our base language for all our APIs and micro-services. It is ultra easy to start with, yet provides great libraries even for the most complex of use cases. Our entire backend stack runs on Python and we cannot be more happy with it! If you are looking to deploy your API as server-less, Python provides one of the least cold start times.

We build our APIs with Flask. For backend database, our natural choice was MongoDB. It frees up our time from complex database specifications - we instead use our time in doing sensible data modelling & once we finalize the data model, we integrate it into Flask using Swagger UI. Mongo supports complex queries to cull out difficult data through aggregation framework & we have even built an internal framework called "Poetry", for aggregation queries.

Our web apps are built on Vue.js , Vuetify and vuex. Initially we debated a lot around choosing Vue.js or React , but finally settled with Vue.js, mainly because of the ease of use, fast development cycles & awesome set of libraries and utilities backing Vue.

You simply cannot go wrong with Vue.js . Great documentation, the library is ultra compact & is blazing fast. Choosing Vue.js was one of the critical decisions made, which enabled us to launch our web app in under a month (which otherwise would have taken 3 months easily). For those folks who are looking for big names, Adobe, and Alibaba and Gitlab are using Vue.

By choosing Vuetify, we saved thousands of person hours in designing the CSS files. Vuetify contains all key material components for designing a smooth User experience & it just works! It's an awesome framework. All of us at FundsCorner are now lifelong fanboys of Vue.js and Vuetify.

On the infrastructure side, all our API services and backend services are deployed as server less micro-services through Zappa. Zappa makes your life super easy by packaging everything that is required to deploy your code as AWS Lambda. We are now addicted to the single - click deploys / updates through Zappa. Try it out & you will convert!

Also, if you are using Zappa, you can greatly simplify your CI / CD pipelines. Do try it! It's just awesome! and... you will be astonished by the savings you have made on AWS bills at end of the month.

Our CI / CD pipelines are built using GitLab CI. The documentation is very good & it enables you to go from from concept to production in minimal time frame.

We use Sentry for all crash reporting and resolution. Pro tip, they do have handlers for AWS Lambda , which made our integration super easy.

All our micro-services including APIs are event-driven. Our background micro-services are message oriented & we use Amazon SQS as our message pipe. We have our own in-house workflow manager to orchestrate across micro - services.

We host our static websites on Netlify. One of the cool things about Netlify is the automated CI / CD on git push. You just do a git push to deploy! Again, it is super simple to use and it just works. We were dogmatic about going server less even on static web sites & you can go server less on Netlify in a few minutes. It's just a few clicks away.

We use Google Compute Engine, especially Google Vision for our AI experiments.

For Ops automation, we use Slack. Slack provides a super-rich API (through Slack App) through which you can weave magical automation on boring ops tasks.

When Redash was created 5 years ago we chose AngularJS as our frontend framework, but as AngularJS was replaced by Angular 2 we had to make a new choice. We decided that we won't migrate to Angular, but to either React or Vue.js. Eventually we decided to migrate to React for the following reasons:

1. Many in our community are already using React internally and will be able to contribute.
2. Using react2angular we can do the migration gradually over time instead of having to invest in a big rewrite while halting feature development.

So far the gradual strategy pays off and in the last 3 major releases we already shipped React code in the Angular.js application.
