koa-lvcnf
Koa middleware for lvcnf.
Installation
npm i koa-lvcnf
Usage
const Koa = require('koa')
const app = new Koa()
const Config = require('lvcnf')
const koaConfig = require('koa-lvcnf')
// config instance to pass into the middleware
const config = new Config(initialConfig)
// other middlewares
app.use(koaConfig({ prefix: '/config', config })) // route prefix
app.listen(8888, () => {
console.log('i am an app!')
})GET /config => all config values
GET /config/foo => config for foo
GET /config/foo.bar.baz => the baz value in { foo: { bar: { baz } } }
DELETE /config/foo.bar.baz => deletes foo.bar.baz
POST /config { "foo": { "bar": 1 } } => merged with current config
PATCH /config/foo.bar.baz => updates foo.bar.baz
Securing The Endpoint
There's no built in security, but you can easily wrap this in your own middleware. Example:
const jwt = require('jwt')
app.use(async (ctx, next) => {
const authCookie = ctx.cookies.get('some-auth-cookie')
const permissions = authCookie && jwt.decode(authCookie).permissions
const canEditConfig = permissions.split(',').includes('configManager')
if (canEditConfig) {
koaConfig({ prefix, config })(ctx, next)
}
await next()
})
