新增db3.js库

开发者可以直接使用typescript 对数据增删该查

// the key seed
const mnemonic ='...'
// create a wallet
const wallet = DB3BrowserWallet.createNew(mnemonic, 'DB3_SECP259K1')
// build db3 client
const client = new DB3Client('http://127.0.0.1:26659', wallet)
const [dbId, txId] = await client.createDatabase()
// create a database
const db = initializeDB3('http://127.0.0.1:26659', dbId, wallet)
// add an index to collection
const indexList: Index[] = [
            {
                name: 'idx1',
                id: 1,
                fields: [
                    {
                        fieldPath: 'name',
                        valueMode: {
                            oneofKind: 'order',
                            order: Index_IndexField_Order.ASCENDING,
                        },
                    },
                ],
            },
]
// create a collecion
const collectionRef = await collection(db, 'cities', indexList)
// add a doc to collection
const result = await addDoc(collectionRef, {
    name: 'beijing',
    address: 'north',
})
// get all docs from collection                                                                                                                                                                  
const docs = await getDocs(collectionRef)
