Package Exports

polymatch

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (polymatch) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

polymatch

Accept: application/json+user will trigger user filter
Accept: application/json+v1+user will trigger both v1 and user filters respectively.
.type(['v1', 'user']) will trigger also.
.type('application/json+v1+user') will trigger also.
filter1.use(filter2) composition works; similar to express-router.
filter1.use({ key: [Function] }) json composition works.

const Polymatch = require('polymatch')
const filters = new Polymatch()

filters
    .on('v1/*')
    .use('user', (input) => {
        // transform for version
        input.uid = input.user_id
        return input
    })
    .use('company:1089', (input) => {
        // transform for specific customer
        input.name = `[${input.name}]`
        return input
    })
    .on('v1/result*')
    .use(require('./filter.result.js'))

// on router and handler
const result = this.filters
                .on('v1/result.xml')
                .input(rows)
                .type(req.get('accept') || ['json'])
                .value()

Try

> a = require('./index.js')
[Function: Polymatch]
> b = new a
Polymatch { targets: [] }
> b.on('a').use('a', (input) => { return 'bbbb' })
Polymatch { targets: [ a: { a: [Function] } ], selectedTarget: 'a' }
> b.on('a').from(3).to('a').value()
3
> b.on('a').from(3).to('ab').value()
3
> b.on('a').from(3).to('absdf').value()
3
> b.on('adsf').from(3).to('absdf').value()
3
> b.on('a').from(3).to(['a']).value()
'bbbb'
> b.on('a').from(3).to('application/json+a').value()
'bbbb'
