现实网络状态

 db3>-$ show-state  name       | state ------------+---------  database   | 1  collection | 0  documemt   | 0  account    | 1  mutation   | 1  session    | 0  storage    | 102.00

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)
