Elm 7 features

ViewForge 9 features

Strong Type System
Elm's type system is designed to catch errors at compile-time, reducing runtime errors and improving code reliability. It emphasizes immutability, making it easier to reason about and maintain code.
No Runtime Exceptions
Elm enforces safety with its type system, ensuring that runtime exceptions are almost impossible. This leads to more robust and predictable applications.
Friendly Error Messages
Elm's compiler provides exceptionally helpful and user-friendly error messages, which make debugging easier and learning the language more approachable.
Optimized Performance
Elm's compiler generates highly optimized JavaScript, resulting in fast and efficient applications. Performance tuning is handled by the compiler, freeing developers from many optimization concerns.
Functional Programming
Elm is purely functional, promoting a clear and declarative coding style. It encourages developers to write more predictable and maintainable code by leveraging functional programming principles.
Built-In Architecture
The Elm Architecture (Model-Update-View) provides a consistent pattern for building applications, which can simplify the development process and improve code organization.
Interoperability with JavaScript
Elm allows you to seamlessly integrate with existing JavaScript code through ports, giving you the flexibility to gradually adopt Elm or work with libraries that are not available in Elm.

Possible disadvantages

Small Ecosystem
Elm's ecosystem is relatively small compared to more established languages like JavaScript or TypeScript, meaning there are fewer libraries and tools available, which might limit certain functionalities out of the box.
Learning Curve
Elm’s functional programming paradigm and strict type system can be challenging for developers who are not familiar with functional programming, leading to a steep learning curve.
Limited Developer Community
The Elm community is smaller compared to other languages, which can make finding support or example projects more difficult. This might also affect the availability of tutorials and learning resources.
Interoperability Overhead
While interoperability with JavaScript is possible through ports, it introduces additional complexity and overhead, making integrated projects more challenging to manage.
Slower Release Cycle
Elm's development and release cycle can be slower compared to other technologies. Updates and new features might take longer to be released, impacting the adoption of cutting-edge practices.
Single File Approach
In Elm, managing large codebases can be problematic due to the lack of support for splitting code into multiple modules or files akin to solutions in other languages, which can make the code less modular and harder to navigate.

Fitment Information
Cascading Year/Make/Model fitment search, up to four levels

Questions & Answers

As answered by people managing Elm and ViewForge.

What makes your product unique?

ViewForge's answer:

Three things. (1) Data ownership: ViewForge writes fitment as Shopify metaobjects native to your store — most competitors store fitment in their own database. (2) 8 verticals out of the box: auto, motorcycle, tractor, marine, power equipment, bicycle, printer, electronics — most competitors are automotive-only. (3) Smart Parse: extract fitment automatically from your existing product titles and descriptions instead of re-typing everything.

Why should a person choose your product over its competitors?

ViewForge's answer:

Data ownership. Fitment lives in your Shopify metaobjects, so uninstalling does not take your compatibility data with it. Convermax, EasySearch and PartFinder all keep it in their own databases, and getting it back depends on their export tooling on the day you cancel.

Cost at the low end. The search widget, the compatibility table on the product page and the saved-vehicle garage are all on the free tier, up to 50 products, with no expiry. EasySearch puts the table and the garage behind its $75/month Premium plan. Convermax starts at $250/month.

Automotive and non-automotive coverage. Eight built-in templates, and fully custom templates from $19/month, for catalogs that do not decompose into Year/Make/Model at all.

How would you describe the primary audience of your product?

ViewForge's answer:

Shopify merchants whose customers need to know whether a part fits before they will buy it — and who do not have an engineer on staff to build that themselves.

Concretely: auto and truck parts retailers, powersports and motorcycle dealers, tractor and agricultural parts sellers, marine and outboard suppliers, small-engine and power equipment stores, bicycle and e-bike component shops, printer supply merchants, and electronics accessory sellers.

Catalog sizes run from a few dozen products on the free tier up into the tens of thousands; it is running in production on a catalog of roughly 40,000 SKUs. The common thread is not the industry — it is that "does this fit my thing" is the question deciding the sale.

What's the story behind your product?

ViewForge's answer:

ViewForge came out of agency work. Normal View was building for a parts retailer running roughly 12,000 SKUs who needed fitment search, and every app we evaluated stored the merchant's compatibility data in the vendor's own database.

That is a strange trade when you look at it directly. Fitment data is genuinely expensive to produce — it is weeks of work — and the merchant would not own the result. It would belong to whichever app happened to be installed that year.

Shopify metaobjects made a different answer possible: write fitment as native structured data inside the merchant's own store. The theme reads it, the Storefront API queries it, Admin GraphQL exports it, and it is still there after an uninstall. That decision is what the rest of the app is built around.

Everything else came from real catalogs rather than a roadmap. Eight verticals exist because a tractor catalog is not Year/Make/Model. Smart Parse exists because that retailer had already written fitment into 12,000 product titles, and nobody was ever going to retype them.

Which are the primary technologies used for building your product?

ViewForge's answer:

TypeScript
Shopify metaobjects, as the fitment data store
Shopify theme app extensions for the storefront components: fitment search, saved-vehicle garage, compatibility table, product-page fit notice
Shopify Storefront API, for querying fitment from the theme
Shopify Admin GraphQL API, for writing and exporting fitment records
NHTSA vehicle database, for VIN decoding
ACES and PIES XML parsing, for automotive catalog import
