data storage service with RESTful APIs.

clannad みんな みんな あわせで ひゃくにんかぞく

Intention & achieved

You will get data you needed, without back-end develop, just APIs.

How it works

how it works


install mongodb first.

$ npm install clannad --save
import clannad from 'clannad';

clannad.configDB((mongoose) => {
  // connection with mongodb

clannad.auth(async (ctx, authArr) => {
  // return authArr by your auth system, or return itself while don't need auth system
  // each authcode is like '${PREFIX}.${PROJECTNAME}.${ROLENAME}'
  // rolename enum as 'master', 'root', 'admin', 'user'
  return await check(ctx, authArr);
}, 'REST'); // prefix for each authcode, default 'REST'

// config for export/import DB format/source
// fields and default value
  db: 'clannad',
  host: '',
  port: 27017,
  user: '',
  password: '',
  out: '' // export filename

// router interface
// These routers are occupied and shouldn't be rewritten.
// /admin, /admin/**, /*/**
clannad.router['get, post...']((ctx) => {
  // dealing mongoose model with ctx.req.model
  // support multipart/* after version 0.4.15

clannad.app.use(...) // clannad's koa app
clannad.app.listen(3000, () => {
  process.stderr.write(`Server running at http://localhost:3000\n`);

About Auth


could use APIs about own project (admin.projects)

  • project's CORS configure with every role (field domains).

project's table (admin.tables)

  • table's availability with each role (field adminAuth, userAuth and visitorAuth).

and table's field (admin.fields)

  • field's visibility with each role (field show).

admin admin and root could use APIs about ${projectName}.${tableName} configured by root, depend on config 'adminAuth' in admin.table.

user could use APIs about ${projectName}.${tableName} configured by root, depend on config 'userAuth' in admin.table.

visitor could use APIs about ${projectName}.${tableName} configured by root, depend on config 'visitorAuth' in admin.table.

token while a request header own field 'X-Token', and it's value exist in that admin.project.tokens, that request will be regarded as a user's request.

list: request (GET) /:projectName/:tablename response [{_id: ...}, ...]

count: request (GET) /:projectName/:tablename/count response {count: ...}

aggregate: request (GET) /:projectName/:tablename/aggregate response {_id: ...}

detail: request (GET) /:projectName/:tablename/detail response {_id: ...}

auth: request (GET) /:projectName/_auth response response {auth: ...}.(0 for visitor, 1 for user, 2 for root, 3 for master)
