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)
