一个面向浏览器的
去中心化应用 SDK

无需服务器。一个 DC 实例，把钱包身份、用户私有库、共享 KeyValue、文件、评论、消息、AI 代理、实时通信、白板和支付统一成同一张能力账簿。

web-dc-api 让前端团队直接在现代浏览器里构建完整的去中心化应用——身份、存储、实时与展示层共享同一个 identity gate。

打开仓库 → 5 分钟接入

#能力注册行数据平面准入

01 ThreadDB 用户私有库每用户 schema 化的私有存储，CRUD 于一人名下 private keyed

02 KeyValue 共享存储命名、类型与权限明确的共享键值平面 shared keyed

03 文件与流文件读写经 ReadableStream，落入同一实例 files keyed

04 实时通信与消息评论、消息、实时连接、白板共享同一身份 live keyed

05 AI 代理与支付高级能力挂在同一 identity core 上按需取用 live keyed

三种数据能力怎么选

同一张账簿，不同的数据平面

大多数应用需求落在三类 row 上：谁的数据、谁共享、以何种形态流动。先澄清这一层，再接第二层能力。

AThreadDB

每用户私有的结构化存储，schema 规则约束，CRUD 限本人。

适用：用户档案、个人笔记、每人可见自己的私有数据。

BKeyValue

共享键值平面，命名字段并声明类型与权限，多名参与者共用。

适用：公共配置、计数、需共享且读写的轻量状态。

C文件

文件作为流读取，经现代浏览器的存储能力落地。

适用：上传附件、二进制资源，需要 ReadableStream 的读取路径。

身份即钥匙

一把钱包钥匙，锁住每一行

所有能力共享同一个 identity gate：钱包登录后，一把密钥通过每一个 padlock，无需分别鉴权或自建账号系统。

钱包登录成为账簿的主键

一次连接，即拿到对整个 data plane 的准入。每行能力的 padlock 都由同一把钥匙打开，跨能力保持一致。

0x登录一次，ThreadDB、KeyValue、实时、文件共享同一身份
0x私有层只对本人开放，共享层由权限字段约束
0x无第三方账号体系，身份由链节点地址与钱包签名构成

调用约定与生命周期

一个实例，从初始化到错误处理

SDK 的调用约定把生命周期标准化：先初始化、再调用各能力、错误走统一的返回方式。

init

初始化配置

传入链节点地址与应用信息，把身份和实例绑定到当前页面。

wallet

钱包登录

建立 identity gate，作为之后每一行能力的准入凭据。

call

按能力调用

对私有库写入查询、对共享层读写、对文件流存取，全部走同一实例。

err

统一错误返回

错误经两类返回方式透出：调用方依约定处理，不混淆能力与身份错误。

运行地基

站在浏览器原生原语之上，不设服务器

SDK 的主要运行目标是现代浏览器。能力账簿的每一层，都由一个原生原语托底。

ES2020

语言基线，语法与运行环境的最低要求。

Web Crypto

钱包签名与密钥运算，身份 gate 的加密支点。

IndexedDB

浏览器内私有存储，用户私有库落地的土壤。

WebSocket

实时通信与白板所需的双向连接。

ReadableStream

文件流读取的前置能力，供文件行启用。

安装与包格式

一条命令，接入账簿

包同时提供 ESM、CommonJS 与 TypeScript 类型，也支持 CDN 加载。

安装

$ npm install web-dc-api
$ pnpm add web-dc-api
$ yarn add web-dc-api

框架接入与版本

React 单例，避免重复连接

面向 React 接入，推荐把实例与初始化 Promise 做成单例，减少重复建立连接。

23:T4ce2, web-dc-api · Decentralized Web Dev SDK

dcnetio / web-dc-api · JavaScript

A browser-oriented
decentralized SDK

No server required. One DC instance unifies wallet identity, user-private DB, shared KeyValue, files, comments, messages, AI agents, real-time comm, whiteboard, and payment as a single capability ledger.

web-dc-api lets frontend teams build complete decentralized apps straight in the browser, with every capability wired through one identity gate.

Open the repo 5-minute setup

#capability rowdata planeaccess

01 ThreadDB user DBSchema-constrained private storage, CRUD scoped to its owner private keyed

02 KeyValue shared storeA shared key-value plane with explicit naming, types and permissions shared keyed

03 Files & streamsFile reads flow through ReadableStream inside the same instance files keyed

04 Realtime & messagesComments, messages, live comm and whiteboard share one identity live keyed

05 AI agents & paymentAdvanced capabilities hang off the same identity core on demand live keyed

three data capabilities

Which plane for which data?

Most needs fall into three rows: whose data, what is shared, and how it flows. Settle that layer before adding capabilities on top.

AThreadDB

Per-user private structured storage, schema-constrained, CRUD owned by the user alone.

Use for: user profiles, personal records, private per-user data.

BKeyValue

A shared key-value plane with named fields, declared types and permissions across participants.

Use for: public config, counters, lightweight shared state.

CFiles

Files read as streams, landed through modern browser storage.

Use for: uploads and binary assets, read via ReadableStream.

identity is the key

One wallet key, sealing every row

Every capability shares the same identity gate: after a wallet login, one key opens every padlock, no per-capability auth or bespoke account system.

Wallet login is the ledger's primary key

One connection grants access to the whole data plane. The padlock on every row is opened by the same key, so identity stays consistent across abilities.

0xLog in once for ThreadDB, KeyValue, realtime and files
0xPrivate layers open to their owner; shared layers are gated by permissions
0xNo third-party account system; identity is chain node address plus wallet signature

call convention & lifecycle

One instance, from init to errors

The SDK standardizes the lifecycle: initialize first, then call each capability, with errors surfacing through a consistent return shape.

init

Initialization config

Supply the chain node URL and app info to bind identity and the instance to the page.

wallet

Wallet login

Establish the identity gate as the credential for every capability row that follows.

call

Call per capability

Write and query the private DB, read and write the shared layer, stream files - all through the same instance.

err

Unified error return

Errors surface through two return modes; callers handle them by convention, without conflating capability and identity failures.

runtime floor

Built on browser primitives, no server

The SDK targets modern browsers. Every layer of the ledger stands on one native primitive.

ES2020

The language baseline and minimum runtime target.

Web Crypto

Wallet signature and key operations power the identity gate.

IndexedDB

In-browser private storage where the user DB lands.

WebSocket

The bidirectional link behind realtime comm and whiteboard.

ReadableStream

The prerequisite for file stream reads, enabling the files row.

install & package

One command, into the ledger

The package ships ESM, CommonJS and TypeScript types, and supports CDN loading.

Install

$ npm install web-dc-api
$ pnpm add web-dc-api
$ yarn add web-dc-api

ESMCommonJSTypeScript typesCDN

framework & release

React singleton, no duplicate connections

For React integration, treat the instance and its init Promise as a singleton to avoid reconnecting.

24:T425,The project's real mechanism is centralized-unify-turned-decentralized: one DC instance in the browser unifying many data capabilities behind one wallet identity with no server. Direction d01's identity-gated capability ledger expresses that mechanism most directly, and its primary source of evidence (the readme's '三种数据能力怎么选' and per-capability CRUD/KV/permission sections) is a register-like list of distinct capabilities — a ledger matrix reads it truthfully. It wins over the capsule (which is evocative but must invent a depth metaphor) and the grounding-column (which foregrounds browser primitives, a secondary fact) because the ledger makes every actual capability row and the shared identity gate visible and checkable without fabricating screenshots. Its flat matte-register surface, no-elevation coplanar rows, and full-width matrix on desktop also recompose cleanly into stacked per-card rows on 390px, and none of its geometry (repeated rows, index rail, key column) collides with any recent fingerprint in antiTemplateContext.25:T61f,The page faithfully implements design brief d01 (identity-gated capability ledger). The hero presents a flat ruled capability matrix as the signature visual — five capability rows (ThreadDB, KeyValue, files/streams, realtime/messages, AI/payment) sharing one index rail and one emerald padlock key column with depth and status cells — all named strictly from readme headings and summary claims. Evidence binding is precise: capability rows, wallet-login identity gate, native browser-primitive floor (ES2020, Web Crypto, IndexedDB, WebSocket, ReadableStream), install commands (npm/pnpm/yarn), package formats (ESM/CJS/TS types/CDN), version v0.2.98, and repo metadata (owner dcnetio, JavaScript, 1003 stars, 3 forks) all trace to material.json facts. Mobile CSS restructures (max-width:900px) genuinely re-piles each ledger row into per-card layout — index becomes a right-aligned tab, gate cell becomes a lock chevron on the right, depth column hides, common index rail becomes the left rail, choose/floor/gate columns stack to single column. Both zh-CN and en are section-for-section equivalent, internally consistent, and naturally localized (zh denser framing, en developer tone). No forbidden patterns (no post-slogan metric-card row, no generic feature-card wall, no browser/terminal/device shell around a fake app, no radial tree/canted dials, no decorative gradient-glow signature). No fake controls — CTAs resolve to the real repo and real in-page anchors, padlocks are aria-hidden decorative glyphs; qa-report confirms fakeControlCount 0.
