dev: {
proxyTable: {
// proxy all requests starting with /api to jsonplaceholder
'/api': {
target: 'http://jsonplaceholder.typicode.com',
changeOrigin: true,
pathRewrite: {
'^/api': ''
}
}
}
}

Provide a filter to formulate routing rules and routing methods.
proxyTable: {
'*': {
target: 'http://jsonplaceholder.typicode.com',
filter: function (pathname, req) {
return pathname.match('^/api') && req.method === 'GET'
}
}
