- Published: Jan 5, 2023
- Type: Announcement

Supabase's December 2022 beta update recaps Launch Week 6, Community Day, Postgres ecosystem work, and other recent releases. The announcements include redesigned documentation rebuilt with Next.js; Storage v2 features for image resizing, webhooks, and a Smart CDN; and multi-factor authentication with optional enforcement through Row Level Security. Supabase Wrappers extend PostgreSQL Foreign Data Wrappers to query external databases, systems, and third-party APIs using SQL, while The Vault enters beta for encrypted secrets and stored data. The update also announces custom domains, point-in-time recovery, SSO on the dashboard in preparation for SAML, and ecosystem projects including pg\_graphql v1.0, a PostgREST 11 pre-release, and an experimental pg\_crdt extension.

React Native Skia’s first year produced an initial alpha and 89 additional releases, evolving a React Renderer and Skia integration for declarative 2D graphics across iOS, Android, the Web, and Node.js testing. The project changed direction after identifying two bottlenecks: dependence on the JavaScript thread and the overhead of thousands of JSI allocations in large drawings. Skia DOM addresses them with a declarative drawing state that recomputes only necessary changes and executes drawings on the UI thread, with C++ implementations on iOS and Android and a JavaScript implementation on React Native Web. CanvasKit compatibility, Expo integration, Metal on iOS, and OpenGL on Android and the Web support the cross-platform design, while extension points enable modules such as Skottie and camera-frame effects. The library’s tests compare rendered examples across platforms, and planned work includes JavaScript-worklet and Reanimated animation integration plus advanced text layouts through Skia’s paragraph module.

Supabase’s Launch Week Day 6 wrap-up consolidates the products and platform changes announced during the event. The roundup announces redesigned Next.js documentation, Storage v2 features for image resizing, webhooks, and a Smart CDN, plus multi-factor authentication usable in Row Level Security policies. It also introduces Wrappers, an Alpha framework for connecting Postgres to external systems, Vault for encrypted secrets, and pg\_graphql 1.0 with general availability. Additional releases include dashboard-enabled point-in-time recovery for Pro Projects, custom domains, pg\_crdt, PostgreSQL 15 for new projects, a PostgREST 11 pre-release, and the PGroonga multilingual full-text search extension. Community partnerships with Flutterflow and OneSignal provide Flutter app development and push-notification integrations.


### [Point in Time Recovery is now available for Pro projects](https://yomu.fyi/post/point-in-time-recovery-is-now-available-for-pro-projects.md)
- Company: [Supabase](https://yomu.fyi/company/supabase.md)
- Author: angelico\_de\_los\_reyes
- Published: Dec 16, 2022
- Type: Announcement

Point-in-Time Recovery (PITR) is now available to eligible Pro Plan projects, expanding access beyond Enterprise customers and adding a Dashboard UI for enabling it. Projects created from August 2022 onward can enable PITR except in Northeast Asia / Seoul, and they must use the Small compute add-on; older projects are not yet generally eligible. The system combines daily physical database snapshots with archived Write Ahead Log (WAL) records, using the open-source WAL-G tool; snapshots are uploaded daily and WAL files are archived as transactions occur. WAL files are backed up at two-minute intervals, potentially faster when a file threshold is reached, reducing the recovery point from the up-to-24-hour exposure of daily backups. PITR backups retain up to seven days by default, with self-serve expansion to 28 days, and restoration can target a specified point in time.


### [Shopify Embraces Rust for Systems Programming](https://yomu.fyi/post/shopify-embraces-rust-for-systems-programming.md)
- Company: [Shopify](https://yomu.fyi/company/shopify.md)
- Author: 2023-10-18

- Type: Announcement

Shopify has adopted Rust as its official systems programming language while retaining Ruby for server-side business logic, and has joined the Rust Foundation. The change addresses growing systems-programming needs including high-performance network servers, Ruby native extensions, and WebAssembly, where Shopify seeks speed, productivity, safety, and community-driven open source. Shopify cites Rust’s predictable native-code performance, fine-grained memory control, compile-time safety, support for concurrency, and interoperability with C and Ruby through tools and crates such as bindgen, rb-sys, and magnus. The company says Rust performed strongly in its safety evaluation and that its initial projects exposed more errors at compile time, while acknowledging that performance still depends on design and measurement and that internal education, tooling, and community participation remain unfinished work.


### [Supabase Storage v2: Image resizing and Smart CDN](https://yomu.fyi/post/supabase-storage-v2-image-resizing-and-smart-cdn.md)
- Company: [Supabase](https://yomu.fyi/company/supabase.md)
- Author: fabrizio,inian
- Published: Dec 13, 2022
- Type: Announcement

Supabase Storage introduces image resizing, webhooks, and a Smart CDN, positioning them as components of an on-demand image delivery system. Resizing uses imgproxy and supports width, height, and contain, cover, or fill modes through JavaScript clients or direct Storage API requests; images are not enlarged beyond their original dimensions, and aspect ratio is preserved by default. The Smart CDN stores resized results using cache keys based on an Etag, tenant ID, bucket, and image name, while webhook-driven metadata updates propagate invalidations globally within about 60 seconds. Image Resizing is beta for Pro and Enterprise customers, with 100 transformed images per project at no additional cost and $5 per additional 1,000; self-hosting is free.


### [pg\_crdt - an experimental CRDT extension for Postgres](https://yomu.fyi/post/pg-crdt-an-experimental-crdt-extension-for-postgres.md)
- Company: [Supabase](https://yomu.fyi/company/supabase.md)
- Author: paul\_copplestone
- Published: Dec 10, 2022
- Type: Announcement

Supabase announces pg\_crdt, an experimental Postgres extension that adds CRDT support as a data type for collaborative and offline-oriented applications. It frames CRDTs as structures whose updates can be merged in any order to reach the same final state, avoiding the last-write-wins behavior of ordinary arrays. A content column can use crdt.ydoc, backed by Yjs, while the extension also supports Automerge through Rust libraries wrapped with pgx. The post contrasts storing CRDTs directly in Postgres with making Realtime an authoritative server, favoring the database-centered approach for simpler architecture and broader tooling, while noting that the decision is unsettled and pg\_crdt is not released on the Supabase platform. Known limitations include full-document WAL broadcasts, increased WAL and dead tuples for frequently updated documents, and serialization overhead for large CRDT values.

Supabase announces its official Launch Week 6 Hackathon, which starts at 8:00am Pacific Time on Friday 9th December 2022 and ends at 00:01am PT on Monday 19th December. The event gives individuals or teams of up to five people ten days to create a new Open Source project using Supabase. Entries may be projects, apps, tools, or libraries in any language or framework, but all design elements and code must be created during the event and each team may submit once. Five categories offer winner and runner-up prizes, including $1500 in GitHub sponsorships paid as three monthly $500 sponsorships for the best overall project, plus Supabase keyboards for its team members. Supabase judges the main categories, while Deno judges Best Edge Functions Project; judging considers creativity, smooth functionality, visual appeal, technical impressiveness, and use of Supabase features.


### [Our Solution for Measuring React Native Rendering Times](https://yomu.fyi/post/our-solution-for-measuring-react-native-rendering-times.md)
- Company: [Shopify](https://yomu.fyi/company/shopify.md)
- Author: 2023-10-18
- Published: Nov 24, 2022
- Type: Tutorial

Shopify needed a reliable way to measure React Native rendering times and verify that mobile apps remained as fast as native while adopting React Native. The open-source @shopify/react-native-performance library measures app startup, navigation, and screen re-render times by timing from native startup, a user action, or a UI event until a screen is fully rendered and interactive. It uses an invisible marker view with a native counterpart to capture end-to-end timing, including React Native-to-native bridge communication, and models incremental rendering as interactive or non-interactive render passes in a state machine. Reports can be sent through onReportPrepared to analytics tools such as Amplitude, where percentile TTI dashboards compare screens over time, expose bottlenecks, and help catch regressions; Shopify also uses screen-level Apdex internally.


### [What We Learned from Open-Sourcing FlashList](https://yomu.fyi/post/what-we-learned-from-open-sourcing-flashlist.md)
- Company: [Shopify](https://yomu.fyi/company/shopify.md)
- Author: 2023-10-18

- Type: Explainer

FlashList is Shopify’s React Native list library, created after Shopify’s migration from native technology exposed poor list performance in React Native. The post explains how a four-person team prototyped a library that combined FlatList’s familiar API with RecyclerListView’s performance, while addressing blank spacing and low frame rates on some devices. It also describes a launch planned six months ahead around a landing page, documentation, blog storytelling, social media, conference exposure, and feedback from external users. The post says FlashList was used in production on some Shopify app screens, and the launch achieved 1,000 GitHub stars in less than 24 hours. The broader conclusion is that successful open-source projects require product thinking, user empathy, community building, and a long-term authority-building strategy in addition to code.


### [Caching Without Marshal Part 2: The Path to MessagePack](https://yomu.fyi/post/caching-without-marshal-part-2-the-path-to-messagepack.md)
- Company: [Shopify](https://yomu.fyi/company/shopify.md)
- Author: 2023-10-18
- Published: Nov 15, 2022
- Type: Problem & solution

Rails caching relied heavily on Marshal, but cached Ruby-specific objects could break after code changes when old payloads were loaded by code without the former classes. MessagePack provided a generic binary format whose core types exclude Ruby-specific Object and instance-variable encodings, while extension types allowed production-specific serializers such as the compact Date representation. During a roughly six-month migration, the team ran both formats, prefixed MessagePack payloads with a version byte, and used encoding failures to identify unsupported cache values. To scale beyond 128 extension types, they added an Object catchall based on as\_pack and from\_pack, plus Struct and T::Struct modules whose attribute digests detect refactors and turn stale data into cache misses. After logs showed that Marshal was no longer used, the core monolith moved exclusively to MessagePack, with the Paquito gem extracting much of the migration work.


### [Mixing It Up: Remix Joins Shopify to Push the Web Forward](https://yomu.fyi/post/mixing-it-up-remix-joins-shopify-to-push-the-web-forward.md)

- Type: Announcement

Shopify announces that the open-source web framework Remix and its team are joining the company to help developers deliver lightning-fast, resilient web experiences. Remix combines multi-page and single-page strengths through a full-stack React framework with data loading and code splitting handled without requiring front-end developers to manage those backend tasks. It also emphasizes progressive enhancement, with links, buttons, and forms working before JavaScript loads, and supports edge, service-worker, and Node runtimes. Shopify will use Remix across projects including Hydrogen; Hydrogen is moving from server components to Remix's data-loading pattern for faster performance and a simpler developer experience, with ~90% of developers' code expected to remain unchanged. Remix will remain independent and open-source while Shopify supports its roadmap and community.


### [What is PostgreSQL commitfest and how to contribute](https://yomu.fyi/post/what-is-postgresql-commitfest-and-how-to-contribute.md)
- Company: [Supabase](https://yomu.fyi/company/supabase.md)
- Author: pavel

- Type: Tutorial

PostgreSQL Commitfest is the community's month-long review process for patches intended for merging into core. Contributors submit patches to pgsql-hackers, create a Git branch from master, consolidate changes, generate a versioned patch, and associate its mailing-list thread with an open Commitfest entry. The process expects authors to explain rationale, respond to review, rebase or revise patches, and review a comparable number of other patches. Submitted changes are checked by CFBot across architectures and operating systems, while statuses such as "Needs review," "Ready for committer," and "Waiting on author" track progress. Commitfests occur five times yearly, with the March event tied to feature-freeze for the October major release.


### [supabase-js v2 Released](https://yomu.fyi/post/supabase-js-v2-released.md)
- Company: [Supabase](https://yomu.fyi/company/supabase.md)
- Author: thor\_schaeff
- Published: Oct 20, 2022
- Type: Announcement

Supabase-js v2 has been released after a release-candidate period during which the team incorporated user feedback and updated documentation, examples, quickstart guides, and a migration guide. The release’s major addition is built-in TypeScript support, including a CLI that generates types directly from a database. It also includes improvements aimed at addressing some of the largest pain points identified by users, with the announcement providing updates and differences from v1. Version 2.0 was produced through contributions from several Supatroopers, more than 100 contributors to the libraries, and more than 450 contributors to the documentation and websites; the listed package contributions include functions-js, gotrue-js, postgrest-js, realtime-js, storage-js, and supabase-js.


### [Finding Relationships Between Ruby’s Top 100 Packages and Their Dependencies](https://yomu.fyi/post/finding-relationships-between-ruby-s-top-100-packages-and-their-depend.md)
- Company: [Shopify](https://yomu.fyi/company/shopify.md)
- Author: 2023-10-18
- Published: Oct 19, 2022
- Type: Explainer

RubyGems’ phased MFA rollout required owners of gems with at least 180 million downloads to use MFA, but raised a supply-chain question: could a popular gem depend on a less-downloaded gem that remained an account-takeover target? The investigation loaded rubygems.org data dumps to identify 112 gems above the threshold, queried the API for direct dependencies, and used Bundler with Gemfile.lock files to resolve transitive dependencies. It found 13 big gems with small direct dependencies and 24 with small dependencies overall, attributing the mismatch mainly to newer dependencies and gems shipped with Ruby, such as racc and rexml. Graph visualizations, breadth-first traversal, and a custom depth-first search then mapped dependency structure and paths; the post leaves open whether to do nothing or enforce MFA early for the 24 technically insecure gems.

- Type: Announcement

Supabase’s September 2022 update centers on reducing technical debt and clearing its backlog after five Launch Weeks. The team ran three Kaizen weeks focused respectively on QA and testing, documentation, and issue backlog and automation, closing over 250 open issues and 50 pull requests while pausing feature development. Product releases included Auth UI, a pre-built React component for Supabase Auth with custom themes and extensible styles, plus an open-source Postgres WASM release with Snaplet for running Postgres in a browser through an embeddable Linux Virtual Machine. Security changes to Dashboard database interactions simplify permissions and reduce the security surface area; they were scheduled for automatic application in November or could be run earlier through the Dashboard. Other updates covered Edge Functions, documentation, migration tooling, and community projects.


### [Postgres WASM by Snaplet and Supabase](https://yomu.fyi/post/postgres-wasm-by-snaplet-and-supabase.md)
- Company: [Supabase](https://yomu.fyi/company/supabase.md)
- Author: burggraf
- Published: Oct 3, 2022
- Type: Explainer

Supabase and Snaplet open-sourced postgres-wasm, a PostgreSQL server that runs inside a browser and supports browser persistence, pg\_dump restoration, and logical replication with a remote database. Rather than compiling PostgreSQL directly to WebAssembly, the project packages a stripped-down Linux image with PostgreSQL in a Buildroot-based virtual machine, then runs it through v86 in the browser. PostgreSQL 14 startup failures were resolved by disabling v86 JIT compilation, while image optimization used a compressed 9P filesystem, asynchronous HTTPS loading, and page\_poison=on to produce an initial state of about 12MB. Websocket proxying provides outbound connectivity and a forked proxy with nginx tunnels incoming connections to PostgreSQL. The project remains experimental because the download is currently about 30MB, but the post identifies offline data, testing, development environments, snapshots, and support as potential uses.


### [Managing React Form State Using the React-Form Library](https://yomu.fyi/post/managing-react-form-state-using-the-react-form-library.md)
- Company: [Shopify](https://yomu.fyi/company/shopify.md)
- Author: 2023-10-18
- Published: Sep 14, 2022
- Type: Tutorial

Shopify’s tutorial shows how to manage a React product form with the open-source react-form library from its Quilt repository. It replaces component-level useState and earlier input and submit handlers with the useForm and useField hooks, which provide form and field state, event handlers, submission, reset, and dirty tracking. The example connects each TextField to its corresponding fields entry, using its value and onChange properties so typed input is captured and displayed. It then wires the hook’s submit function, resets the form after data is handled, and disables Save until either field changes. Finally, the notEmpty validation hook requires a title and displays a required-field error when a submission contains only a description.

Supabase’s August 2022 Beta Update recaps Launch Week 5 releases, the Supa Hackathon, platform changes, migration resources, and community contributions. The release set includes Supabase CLI v1 with TypeScript type generation, the Management API Beta for programmatic project and organization control, and the supabase-js v2 release candidate with type support, new authentication methods, an async Auth overhaul, and Edge Functions improvements. Supabase also announced SOC2 compliance and made Realtime Presence and Broadcast available to all projects, alongside Vault, Auth UI, dashboard permissions, JSON schema validation, pg\_graphql v0.4.0, and MFA early access. From September 11, HTTP API requests will redirect to HTTPS, and clients no longer need to send anon or service keys in the apiKey header; client-library users require no change.

Ruby Central has posted videos from RailsConf talks and workshops online, following the 2022 in-person conference where several Shopify Ruby on Rails team members attended and around a dozen gave talks. The collection features ten Shopify sessions on Rails’s state, Ruby’s YARV virtual machine, cache serialization, algorithmic complexity, historical Ruby gems, supply-chain attacks, team trust, GraphQL delivery, and regular-expression denial-of-service attacks. Several talks use concrete technical examples: MessagePack replaced Marshal in the core monolith’s cache, OpenTelemetry is used to diagnose performance issues, and one tutorial demonstrates GraphQL delivery through WebSockets, Webhooks, WebAssembly code, and Bulk Operations. The sessions also connect implementation details with broader engineering practices, including investment in open-source teams, playful problem solving, pair programming, Rubocop, compilers, and examining older code to inform current decisions.
