Dexie.js auto-increment ++id generated key type number explicit string key IndexedDB

💡 Result:

In Dexie.js and the underlying IndexedDB, using an auto-incrementing primary key (defined via ++id in Dexie's schema) has specific behaviors regarding key types and explicit assignments. Key Types and Auto-Incrementing When you define a schema with ++id, you are using an IndexedDB object store with the autoIncrement flag enabled [1][2][3]. - The auto-incrementing key generator in IndexedDB is designed to produce positive integers [2][4]. - While you can explicitly provide a different key (such as a string) when adding or putting an object into a store, the key generator only tracks numeric keys [2][4]. - If you provide an explicit key that is a string, IndexedDB will use that specific string as the primary key for that record [4]. This does not interfere with the auto-increment counter, which only updates based on numeric keys [4]. Behavior when providing an explicit string key If you have a table defined with ++id and you attempt to add an object that contains a string value for that id field: 1. Dexie/IndexedDB will respect the explicit string key you provided [4]. 2. The object will be stored with that string as its primary key [4]. 3. The internal auto-increment counter will remain unaffected by the string key; the next time you add an object without an id, the generator will continue from its last numeric value [4]. Summary of key behaviors in Dexie.js: - ++id: Auto-incrementing integer primary key (inbound) [5][1]. - id: Explicit primary key (you must provide it yourself) [5][6]. - @id: Globally unique string ID (requires dexie-cloud-addon) [5][6]. In practice, if you need the primary key to be a string and want it to be automatically generated, you should typically avoid the ++ syntax, which is specifically for numeric auto-incrementing, and instead manage the generation of string IDs in your application logic or use the @id syntax if utilizing Dexie Cloud [5][6].

Dexie Table.add autoIncrement generated key assigned to inbound keyPath object id

💡 Result:

When you use table.add (or table.put) in Dexie.js with a schema that specifies an auto-incremented primary key (denoted by ++ in the schema definition) and an inbound keyPath, Dexie automatically assigns the generated key to the corresponding property on the object [1][2]. Key details regarding this behavior: 1. Automatic Assignment: If the primary key property is missing or undefined on the object being added, Dexie detects the auto-incremented status and the generated ID is injected into the object's keyPath property [1][3][2]. 2. Scope: This automatic assignment occurs specifically with table.add and table.put [1][2]. It does not happen with bulk operations such as table.bulkAdd or table.bulkPut [1][2]. 3. Promise Result: The promise returned by table.add resolves with the newly generated primary key [1][4]. 4. TypeScript Considerations: To maintain proper type safety in TypeScript (specifically for Dexie 4+), it is recommended to use the EntityTable helper or define an explicit InsertType that makes the primary key optional, allowing you to pass objects without the ID property while still enjoying full type inference after retrieval [5]. This functionality relies on the library internally handling the mutation of the provided object to populate the generated value [3]. If you need to perform custom logic or manual intervention during this process, the hook('creating') event is available [6].

Align APISpec.id with the Dexie key type. APISpec.id is string, so '1' and '2' are valid test values. However, ++id generates numeric IDs for new records and conflicts with the declared type and string-based consumers.
