indexdb

README

tinywasm/indexdb

implementación de index dB con Websassembly compilado con go (golang)

Usage

db := indexdb.InitDB("my_db", idGenerator, logger, &User{}, &Product{})

This single-line initialization instantly yields a fully functioning *orm.DB ready for use with the github.com/tinywasm/orm API.

Functions

func CheckCondition

func CheckCondition(val js.Value, cond orm.Condition) bool

CheckCondition checks if a JS value satisfies a condition

func InitDB

func InitDB(dbName string, idg idGenerator, logger func(...any), structTables ...any) *orm.DB

InitDB initializes the IndexedDB database and returns an *orm.DB instance.

func MapResult

func MapResult(val js.Value, m orm.Model) error

MapResult maps a JS value to a Model's pointers

func ProcessCursorRequest

func ProcessCursorRequest(req js.Value, onNext func(cursor js.Value) bool) error

ProcessCursorRequest handles an IndexedDB cursor request (openCursor). It iterates over the cursor and calls the provided callback for each item.

func ProcessRequest

func ProcessRequest(req js.Value) (js.Value, error)

ProcessRequest handles an IndexedDB request (like add, put, get, delete) and returns the result or error via channels.

Types

type IndexDBAdapter

type IndexDBAdapter struct {
	// contains filtered or unexported fields
}

func NewAdapter

func NewAdapter(dbName string, idg idGenerator, logger func(...any)) *IndexDBAdapter

NewAdapter creates a new IndexDBAdapter.

func (*IndexDBAdapter) Close

func (d *IndexDBAdapter) Close() error

Close implements orm.Executor

func (*IndexDBAdapter) Exec

func (d *IndexDBAdapter) Exec(query string, args ...any) error

Exec implements orm.Executor

func (*IndexDBAdapter) Execute

func (d *IndexDBAdapter) Execute(q orm.Query, m orm.Model, factory func() orm.Model, each func(orm.Model)) error

Execute implements orm.Adapter for IndexDB.

func (*IndexDBAdapter) GetNewID

func (d *IndexDBAdapter) GetNewID() string

Helper to access the ID generator

func (*IndexDBAdapter) Initialize

func (d *IndexDBAdapter) Initialize(structTables ...any)

Initialize initializes the IndexedDB database and creates object stores based on the provided structs.

func (*IndexDBAdapter) Query

func (d *IndexDBAdapter) Query(query string, args ...any) (orm.Rows, error)

Query implements orm.Executor

func (*IndexDBAdapter) QueryRow

func (d *IndexDBAdapter) QueryRow(query string, args ...any) orm.Scanner

QueryRow implements orm.Executor

func (*IndexDBAdapter) TableExist

func (d *IndexDBAdapter) TableExist(table_name string) bool

TableExist checks if a table exists in the database

type IndexDBCompiler

type IndexDBCompiler struct{}

Compiler converts ORM queries into engine instructions.

func (*IndexDBCompiler) Compile

func (c *IndexDBCompiler) Compile(q orm.Query, m orm.Model) (orm.Plan, error)
