Instead of writing ad hoc mapping functions, developers register schemas and define migrations between them; doba automatically chains migrations to find paths between schemas that have no direct transform defined. It also supports a migration context for recording defaulted or guessed values during conversions, a pipe builder for mechanical renames/drops with type-checked chaining, and schema identification for unknown incoming data via field matchers. Use cases highlighted include API versioning, LLM prompt formatting, legacy data imports, and webhook payload normalization. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How can I automatically chain data transformations between schemas that don't have a direct migration defined in TypeScript? A schema registry can walk a graph of defined migrations and chain intermediate ones automatically. For example, if only database-to-frontend and frontend-to-ai migrations are registered, calling a transform from database to ai still works because the registry routes through the frontend schema, without requiring a direct database-to-ai migration to be written. _Developers comparing data-mapping approaches can find write-ups like this on daily.dev._ ### How do I track why fields were defaulted during a legacy data migration in TypeScript? Pass a context object into each migration function that exposes methods like ctx.defaulted() and ctx.warn() to record decisions made during conversion, such as generating a missing id or guessing an email from a name field. These records appear in the transform result's meta.defaults and meta.warnings arrays so the reasoning is preserved instead of disappearing into function bodies. _Teams handling messy legacy imports often track patterns like this via daily.dev._ ### How can I detect which schema an unknown piece of data matches before transforming it in a TypeScript app? Define identify guards per schema using field matchers such as match.field('passwordHash') or match.fields('createdAt', 'settings'), then call identifyAndTransform on the unknown data and a target schema name. Guards run in definition order, detecting the source schema, chaining the migration path, and returning a typed error rather than crashing if nothing matches. _daily.dev surfaces practical patterns like this for developers normalizing inconsistent payloads._ ## Similar posts on daily.dev - [Valibot v1.5: Faster schema construction, Unicode code points, and stricter validation](https://daily.dev/posts/valibot-v1-5-faster-schema-construction-unicode-code-points-and-stricter-validation-fcqzm9kyo) · Valibot: The modular and type safe schema library · 5 upvotes · 1 comments - [Transformations that know their context](https://daily.dev/posts/transformations-that-know-their-context-bmidy29zd) · dltHub · 1 upvotes · 0 comments - [DumboDB: Announcing Validator Support](https://daily.dev/posts/dumbodb-announcing-validator-support-pxoap3acs) · DoltHub Blog · 12 upvotes · 0 comments - [Evolutionary Data Through Schemaboi: Achieving Forward, Backwards, and Sideways Compatibility](https://daily.dev/posts/evolutionary-data-through-schemaboi-achieving-forward-backwards-and-sideways-compatibility-vnkox1i6x) · InfoQ · 0 upvotes · 0 comments --- Tags: [#typescript](https://daily.dev/tags/typescript) [View this post on daily.dev](https://daily.dev/posts/one-model-many-views-type-safe-transforms-with-valibot-and-doba-jdqcdjqot) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"One Model, Many Views: Type-Safe Transforms with Valibot and doba","url":"https://daily.dev/posts/one-model-many-views-type-safe-transforms-with-valibot-and-doba-jdqcdjqot","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/one-model-many-views-type-safe-transforms-with-valibot-and-doba-jdqcdjqot"},"datePublished":"2026-08-23T12:23:35.370Z","dateModified":"2026-08-23T12:55:18.364Z","description":"A guest post introduces doba, a schema registry library that pairs with Valibot (or any Standard Schema compatible library) to manage type-safe transformations...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/979f239bb1ad0d6b272fb7ec4ad35850?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/979f239bb1ad0d6b272fb7ec4ad35850?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"Valibot: The modular and type safe schema library","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Valibot: The modular and type safe schema library","logo":"https://media.daily.dev/image/upload/s--GHNQZY4x--/f_auto,q_auto/v1787487507/logos/valibot?_a=BAMAMicg0","url":"https://daily.dev/sources/valibot"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/one-model-many-views-type-safe-transforms-with-valibot-and-doba-jdqcdjqot","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"typescript","timeRequired":"PT6M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Valibot: The modular and type safe schema library","item":"https://daily.dev/sources/valibot"},{"@type":"ListItem","position":3,"name":"One Model, Many Views: Type-Safe Transforms with Valibot and doba"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/one-model-many-views-type-safe-transforms-with-valibot-and-doba-jdqcdjqot#faq","mainEntity":[{"@type":"Question","name":"How can I automatically chain data transformations between schemas that don't have a direct migration defined in TypeScript?","acceptedAnswer":{"@type":"Answer","text":"A schema registry can walk a graph of defined migrations and chain intermediate ones automatically.
