dimensions ​

dimensions: number = null

Defined in: core/src/schema/property/base/SchemaBase.ts:35

How many numbers a vector holds. null for every other type.

Declared here rather than on SchemaVector because a modifier WRAPS rather than extends: s.vector(1536).optional() is a SchemaOptional, and anything reachable only through the original class is lost the moment a modifier is added. type survives for exactly this reason — the copy constructor below carries it — and a dimension count has to travel with it, or an optional vector reaches a backend as a vector of unknown width and cannot be given a column.

innerSchema is the cautionary example: it lives on SchemaArray alone, so a modified array arrives with no element type and clones through the slow path.

Inherited from ​

SchemaBase.dimensions

maxLength ​

maxLength: number = null

Defined in: core/src/schema/property/base/SchemaBase.ts:50

The longest string the property is declared to hold. null for every other type, and for a string that declares nothing.

Declared here rather than on SchemaString for the same reason as dimensions above: s.string({ maxLength: 4000 }).optional() is a SchemaOptional, so anything reachable only through SchemaString is lost the moment a modifier is added.

A declaration, never a validation. Core does not check a value against it and does not truncate. The backend that can use the number does: MySQL gives the column VARCHAR(maxLength) instead of the blanket VARCHAR(255). Every other backend ignores it, because a string column that is already unbounded cannot be made more correct by knowing a bound.

Inherited from ​

SchemaBase.maxLength

isSearchable ​

isSearchable: boolean = false

Defined in: core/src/schema/property/base/SchemaBase.ts:62

Whether this string may be tokenised into a full-text search index.

Set by .searchable(), and only ever true on a string. Eligibility, not membership: a collection that never declares .searchIndex() indexes nothing regardless.

Copied by the constructor below, so s.string().searchable().optional() stays searchable. Every flag on this class is copied for the same reason: a modifier WRAPS rather than extends, so anything the constructor forgets is silently dropped the moment a property gains one more modifier.

SchemaBase.isSearchable

Accessors ​

~standard ​

Get Signature ​

get ~standard(): Props<InferCreateType<T>, InferType<T>>

Defined in: core/src/schema/SchemaDefinition.ts:197

Standard JSON Schema V1 implementation. Provides JSON Schema conversion for Routier schemas.

Returns ​

Props<InferCreateType<T>, InferType<T>>

Methods ​

fromJson() ​

static fromJson(jsonString, collectionName?): CompiledSchema<any>

Defined in: core/src/schema/SchemaDefinition.ts:188

Creates a SchemaDefinition from a JSON string containing a JSON Schema. Parses the JSON string, rehydrates the schema structure, and compiles it.

Parameters ​

jsonString ​

string

The JSON string containing the JSON Schema (typically from schema['~standard'].jsonSchema.input() or output())

collectionName? ​

string

Optional collection name override (if not present in JSON Schema metadata)

Returns ​

CompiledSchema<any>

A compiled schema ready to use

Throws ​

Error if the JSON string is invalid or doesn't contain a valid JSON Schema

Example ​

typescript
// Serialize a schema to JSON
const jsonSchema = mySchema['~standard'].jsonSchema.input({ target: 'draft-2020-12' });
const jsonString = JSON.stringify(jsonSchema);

// Rehydrate from JSON string
const rehydratedSchema = SchemaDefinition.fromJson(jsonString);
// Schema is already compiled and ready to use
