No account, API key or authentication required. - **Medusa Plugins** - [Introduction](https://zanreal.com/docs/medusa-plugins): The Medusa v2 plugins ZanReal develops in the open - what they are for, how they fit together, and what installing one into a Medusa project involves. - Admin Kit: @zanreal/medusa-admin-kit is an extensible Catalog table for the Medusa v2 admin, and the column registry sibling plugins write to. - [Overview](https://zanreal.com/docs/oss/medusa-admin-kit): A Medusa v2 plugin that owns one extensible catalogue table, plus the column registry sibling plugins import to put their own data into it. - [The Catalog table](https://zanreal.com/docs/oss/medusa-admin-kit/catalog): One row per variant, the seven base columns the kit renders itself, and the rules every money cell in the table follows. - [Contributing a column](https://zanreal.com/docs/oss/medusa-admin-kit/columns): How another Medusa plugin registers a column in the shared Catalog table, the one evaluation-order rule that silently breaks it, and how async cells work. - [API reference](https://zanreal.com/docs/oss/medusa-admin-kit/api): Every export of @zanreal/medusa-admin-kit - the column registry, the context builders, the money readers, the query mappers and the types. - Allegro: @zanreal/medusa-allegro is Allegro marketplace sync for Medusa v2: offers keyed by SKU, bounded price writes, stock, and the order event drain. - [Overview](https://zanreal.com/docs/oss/medusa-allegro): A Medusa v2 plugin for Allegro, Poland's largest marketplace - offers matched by SKU, price writes fenced between a break-even floor and an SRP ceiling, stock reconciliation, and an order event drain. - [Connecting an account](https://zanreal.com/docs/oss/medusa-allegro/connecting): Registering an Allegro application, generating the encryption key that seals the stored tokens, running the OAuth flow from the admin, and what protects the callback. - [Offers, SKUs and stock](https://zanreal.com/docs/oss/medusa-allegro/mapping): The sygnatura contract that links a Medusa variant to an Allegro offer, the five mapping conflicts the plugin records instead of resolving, and why the stock loop refuses a whole plan rather than push half of one. - [Pricing](https://zanreal.com/docs/oss/medusa-allegro/pricing): The three pricing modes, the break-even floor and the SRP ceiling that bound every one of them, the reasons an offer is skipped, and the machinery that limits the damage a bad run can do. - [Orders and invoices](https://zanreal.com/docs/oss/medusa-allegro/orders): Draining Allegro's order event journal into Medusa orders, the derived status ladder, fulfillment write-back, and attaching an issued invoice PDF to the Allegro order. - [Configuration and control](https://zanreal.com/docs/oss/medusa-allegro/configuration): Every plugin option and environment variable, the persisted runtime toggles that arm each writer, the precedence rules between the three layers, and the runbook for turning the writers on. - Usage: @zanreal/medusa-usage is metered usage for Medusa v2: an append-only event log, deterministic deduplication, billing periods and rating. - [Overview](https://zanreal.com/docs/oss/medusa-usage): Metered usage for Medusa v2 - an append-only event log, deterministic deduplication, billing periods and rating, ending at a frozen number your application invoices. - [Recording and reading usage](https://zanreal.com/docs/oss/medusa-usage/recording): The three ways to record an event, why quantity has to be a whole number, why ingestion is batched, half-open windows, reading an aggregate back, and how a correction works on a log that never allows an update. - [Deduplication, in full](https://zanreal.com/docs/oss/medusa-usage/deduplication): How an event's key is derived from what it means rather than generated, the two forms that derivation takes, and why that is what makes a retry free instead of a double charge. - [Billing periods](https://zanreal.com/docs/oss/medusa-usage/billing): Opening and closing a period, rating usage against a configured rate card, the frozen result that comes out of closing, what happens to a late event, and how to turn a closed period into an invoice. - [Sinks and configuration](https://zanreal.com/docs/oss/medusa-usage/sinks): The sink provider contract, every plugin option with its default, the admin API surface, the one environment variable, and how to write a sink of your own. - Tinybird Sink: @zanreal/medusa-usage-tinybird is the Tinybird sink for @zanreal/medusa-usage: the same append-only usage log, deduplicated on read so a retry cannot double count. - [Overview](https://zanreal.com/docs/oss/medusa-usage-tinybird): The Tinybird sink for @zanreal/medusa-usage - the same append-only usage log, in a column store built to scan billions of rows of it. - [Exactly-once reads on a store with no primary key](https://zanreal.com/docs/oss/medusa-usage-tinybird/consistency): Why this sink's at-most-one-row-per-key guarantee lives in the read path instead of the write path, why that is not a workaround, and exactly what stays eventual because of it. - FX Pricing: @zanreal/medusa-fx-pricing derives USD and EUR variant prices from the NBP table A mid rate the moment the PLN price changes, with a margin you choose and manual prices left untouched. - [Overview](https://zanreal.com/docs/oss/medusa-fx-pricing): A Medusa v2 plugin that derives USD and EUR variant prices from a store's PLN price using the NBP table A mid rate, the moment that PLN price changes, without ever overwriting a price a human set. - [Rates, and days without one](https://zanreal.com/docs/oss/medusa-fx-pricing/rates): Which NBP endpoint the plugin calls, why a weekend needs no special case, what the staleness tolerance measures, and the three reasons a currency is skipped for a whole run. - [Manual overrides](https://zanreal.com/docs/oss/medusa-fx-pricing/overrides): Why the ownership marker cannot live on the price row, what the FxManagedPrice stamp records, the four branches the decision takes, and the one way to hand a price back to the plugin. - [Settings and configuration](https://zanreal.com/docs/oss/medusa-fx-pricing/settings): Every plugin option and where it can be overridden, why the margin ships without a default, the two environment variables, the admin page, and the two admin API routes. - Product Costs: @zanreal/medusa-product-costs tracks purchase cost (COGS) per SKU for Medusa v2, with an append-only history and margin, break-even and net income derived from it. - [Overview](https://zanreal.com/docs/oss/medusa-product-costs): Purchase cost (COGS) per SKU for Medusa v2 - a curated net cost, an append-only history of every change, and margin, break-even and net income derived from it without a single guessed input. - [Costs, history and the variant link](https://zanreal.com/docs/oss/medusa-product-costs/costs): How a cost is stored, why the SKU owns the row instead of the variant, what makes the audit trail genuinely append-only, and when the variant link needs a resync. - [Margin, break-even and the math](https://zanreal.com/docs/oss/medusa-product-costs/economics): The four figures this plugin derives, exactly which inputs each one needs, why a missing input yields nothing rather than zero, and the double-rounding bug the implementation is written to avoid. - [Bulk import from CSV](https://zanreal.com/docs/oss/medusa-product-costs/import): The two-column file the importer accepts, how it works out the delimiter and the decimal separator without asking, what it refuses to guess, and why link resolution is deferred to a second pass. - [Settings and the admin API](https://zanreal.com/docs/oss/medusa-product-costs/settings): The two module options, why neither ships a default, how the persisted singleton overrides them without a restart, and a reference for every admin route. - inFakt: Polish invoicing for Medusa v2: inFakt invoices for paid orders, KSeF filing for the B2B ones, and a durable pipeline that parks anything ambiguous for a human. - [Overview](https://zanreal.com/docs/oss/medusa-infakt): Polish invoicing for Medusa v2 - issues inFakt invoices for paid orders, files the B2B ones to KSeF, and parks anything ambiguous for a human instead of guessing. - [The invoicing pipeline](https://zanreal.com/docs/oss/medusa-infakt/invoicing): From the trigger event to a finished invoice - the fully-paid gate, the five skip conditions, the durable state machine, the crash window that is never retried, and how backoff works. - [KSeF filing](https://zanreal.com/docs/oss/medusa-infakt/ksef): The three modes and why the setting is not a boolean, what makes an invoice B2B, the startup health check, and what a KSeF rejection does to a row. - [Reconciliation and adoption](https://zanreal.com/docs/oss/medusa-infakt/reconciliation): Matching invoices that already exist in inFakt to the orders they belong to - the three hard gates, why line names are never a signal, the confidence grades, and the dry run that comes first. - [Settlement reconciliation](https://zanreal.com/docs/oss/medusa-infakt/settlement): Does inFakt agree that these orders were paid - why paid_date is the only durable signal, the five drift codes, the ninety-day sliding window, and why nothing is fixed automatically. - [Settings and the admin API](https://zanreal.com/docs/oss/medusa-infakt/settings): Every plugin option, the admin-editable overrides that need no redeploy, the three switches that can turn invoicing off, and a reference for every admin route. -

The API is unchanged - same exports, same signatures - so migrating is a rename and a codemod. - [ZanReal OSS Program](https://zanreal.com/docs/oss/nemo/latest/stewardship): NEMO started in 2024 as one developer's answer to a gap in Next.js middleware. ZanReal maintains it now, and this is what that changes for you. - [Configuration](https://zanreal.com/docs/oss/nemo/latest/configuration): The three arguments of createNEMO: the route map, global middleware that runs on every request, and the options that change how the chain behaves. - [Route matchers](https://zanreal.com/docs/oss/nemo/latest/matcher): NEMO matches routes with path-to-regexp, the same syntax Next.js uses - named parameters, wildcards, and how matched values reach your functions. - [Advanced Route Matching](https://zanreal.com/docs/oss/nemo/latest/advanced-matching): Beyond plain paths: restrict a parameter to a set of values, exclude specific ones, and fall back to regular expressions when a pattern needs it. - [Nested Routes](https://zanreal.com/docs/oss/nemo/latest/nesting): Arrange middleware in a hierarchy that mirrors your route tree - execution order, stopping the chain early, and reading params from higher levels. - [Functions](https://zanreal.com/docs/oss/nemo/latest/functions): A NEMO middleware function has the same signature as a native Next.js one, so third-party functions drop straight in. Headers, events and returns. - [Storage](https://zanreal.com/docs/oss/nemo/latest/context): Share data between functions in one chain: fetch the user once in an early function and read it from storage in every function that runs after it. - [Best practices](https://zanreal.com/docs/oss/nemo/latest/best-practices): Middleware runs before every request, so each millisecond lands in TTFB. Performance, security and reliability practices for a production chain. - **Conventions** - [Project structure](https://zanreal.com/docs/oss/nemo/latest/conventions/project-structure): NEMO collects configuration in one entry file, but nothing says the function bodies belong there too. Where to put them as an application grows. - [Functions naming](https://zanreal.com/docs/oss/nemo/latest/conventions/functions-naming): Why middleware is the one word to keep out of a middleware function name, and how to name a dozen of them so the entry file still reads clearly. - **3rd parties** - Packages - [Supabase](https://zanreal.com/docs/oss/nemo/latest/3rd-parties/supabase): Run Supabase session refresh inside a NEMO chain, so refreshed cookies reach the response and the functions after it see the signed-in user. - [NextAuth (Auth.js)](https://zanreal.com/docs/oss/nemo/latest/3rd-parties/next-auth): Wire Auth.js into a NEMO chain so the session it resolves is available to every function that runs after it, without a second lookup per request. - v2: Previous major - **Getting started** - [Getting started](https://zanreal.com/docs/oss/nemo/v2): Getting started on the NEMO v2 line: install the package, import it in your middleware file and dispatch the first routes from one entry point. - [Migrating to @zanreal/nemo](https://zanreal.com/docs/oss/nemo/v2/migration): Moving from @rescale/nemo to @zanreal/nemo: the v3.0.0 scope change with an unchanged API, and the codemod that rewrites the imports for you. - [Configuration](https://zanreal.com/docs/oss/nemo/v2/configuration): How createNEMO is configured on the v2 line - the route map, middleware that runs globally, and the options that change the chain's behaviour. - [Route matchers](https://zanreal.com/docs/oss/nemo/v2/matcher): Route matching on the v2 line uses path-to-regexp - patterns, named parameters, and how matched values are passed into your middleware functions. - [Advanced Route Matching](https://zanreal.com/docs/oss/nemo/v2/advanced-matching): Advanced v2 patterns: restrict a parameter to a set of values, exclude specific ones, and drop to a regular expression when a pattern needs more. - [Nested Routes](https://zanreal.com/docs/oss/nemo/v2/nesting): Nested routes on the v2 line: build a middleware hierarchy that mirrors your route tree, control execution order and stop the chain when needed. - [Functions](https://zanreal.com/docs/oss/nemo/v2/functions): Middleware functions on the v2 line use the native Next.js signature, so third-party functions drop in unchanged. Headers, events and returns. - [Storage](https://zanreal.com/docs/oss/nemo/v2/context): Storage on the v2 line: share data across a single chain so a value fetched in an early function is readable by every function that follows it. - [Best practices](https://zanreal.com/docs/oss/nemo/v2/best-practices): Practices for a v2 middleware chain in production - keeping execution time out of TTFB, handling secrets carefully, and failing safely at scale. - **Conventions** - [Project structure](https://zanreal.com/docs/oss/nemo/v2/conventions/project-structure): Where middleware function bodies live on the v2 line once configuration is centralised in one entry file, and how that arrangement scales up. - [Functions naming](https://zanreal.com/docs/oss/nemo/v2/conventions/functions-naming): Naming middleware functions on the v2 line so an entry file holding a dozen of them stays readable - and why middleware is not part of a name. - **3rd parties** - Packages - [Supabase](https://zanreal.com/docs/oss/nemo/v2/3rd-parties/supabase): Integrating Supabase session refresh with a NEMO v2 chain so refreshed cookies reach the response and later functions see the signed-in user. - [NextAuth (Auth.js)](https://zanreal.com/docs/oss/nemo/v2/3rd-parties/next-auth): Integrating Auth.js with a NEMO v2 chain so the resolved session is shared with every function that runs after it within the same request. - v1: Archived - **Guide** - [Getting started](https://zanreal.com/docs/oss/nemo/v1): Getting started on the v1.4 line, published as @rescale/nemo. Kept for existing projects - new work should start on the current major instead. - [Configuration](https://zanreal.com/docs/oss/nemo/v1/configuration): createMiddleware on the v1.4 line: the entry point that turns a path-keyed map into one Next.js middleware export. Legacy documentation. - [Route matchers](https://zanreal.com/docs/oss/nemo/v1/matcher): Route matching on the v1.4 line with path-to-regexp - patterns, named parameters, and how matched values reached your middleware functions. - [Functions](https://zanreal.com/docs/oss/nemo/v1/functions): Middleware function standardisation as it worked on the v1.4 line, before the API moved to the native Next.js signature in later majors. - [Shared context](https://zanreal.com/docs/oss/nemo/v1/context): Shared context on the v1.4 line let functions in one chain pass data between each other. Superseded by storage in the majors that followed. - [Forward](https://zanreal.com/docs/oss/nemo/v1/forward-functions): Forward functions on the v1.4 line pass one middleware's response into the next, chaining behaviour across a request. Legacy documentation. - **Conventions** - [Project structure](https://zanreal.com/docs/oss/nemo/v1/conventions/project-structure): How the v1.4 line suggested organising middleware across a project's directories, kept for reference alongside the current guidance. - [Functions naming](https://zanreal.com/docs/oss/nemo/v1/conventions/functions-naming): Naming conventions for middleware functions on the v1.4 line, kept as published for projects that have not yet migrated to a newer major. - **API Reference** - [Supabase](https://zanreal.com/docs/oss/nemo/v1/api-reference/supabase): Supabase integration as documented on the v1.4 line, using @rescale/nemo. Newer majors cover the same ground under their 3rd-parties section. --- ## Recent Blog Posts - [VPN: What It Is, How It Works and When to Use It](https://zanreal.com/blog/vpn-what-it-is-how-it-works-and-when-to-use-it) - [EDR or Antivirus: What Is the Difference, and What Does Your Business Need?](https://zanreal.com/blog/edr-or-antivirus-whats-the-difference-and-what-does-your-business-need) - [How much does a cheap website really cost?](https://zanreal.com/blog/how-much-does-a-cheap-website-really-cost) - [Software Updates in Business: Why They Matter and How to Deploy Them Safely](https://zanreal.com/blog/software-updates-in-business-why-they-matter-and-how-to-deploy-them-safely) - [How to Start Implementing AI in Your Company: Practical First Steps](https://zanreal.com/blog/how-to-start-implementing-ai-in-your-company) - [Jev vs LLMs: when a fast decision model is the better choice](https://zanreal.com/blog/jev-vs-llms-when-a-fast-decision-model-is-the-better-choice) - [Hardware Security Keys: What They Are, When to Use Them and How to Choose the Right Model](https://zanreal.com/blog/hardware-security-keys-what-they-are-when-to-use-them-how-to-choose) - [Business Backups: How to Protect Your Data from Hardware Failure and Ransomware](https://zanreal.com/blog/business-backups-how-to-protect-your-data-from-hardware-failure-and-ransomware) - [Website in 24 Hours or a Custom Website Project: Which Should You Choose?](https://zanreal.com/blog/website-in-24-hours-or-a-custom-website-project-which-should-you-choose) - [Fake ChatGPT payment emails: criminals impersonate OpenAI.
