Nate158s / Digital Marketing # Routing with EdgeJS https://github.com/Nate158s The `{{ PACKAGE_NAME }}/core` package provides a JavaScript API for controlling routing and caching from your code base rather than a CDN web portal. Using this _{{ EDGEJS_LABEL }}_ approach allows this vital routing logic to be properly tested, reviewed, and version controlled, just like the rest of your application code. Using the Router, you can: - Proxy requests to upstream sites - Send redirects from the network edge - Render responses on the server using Next.js, Nuxt.js, Angular, or any other framework that supports server side rendering. - Alter request and response headers - Send synthetic responses - Configure multiple destinations for split testing ## Configuration To define routes for {{ PRODUCT_NAME }}, create a `routes.js` file in the root of your project. You can override the default path to the router by setting the `routes` key in `{{ CONFIG_FILE }}`. The `routes.js` file should export an instance of `{{ PACKAGE_NAME }}/core/router/Router`: ```js // routes.js const { Router } = require('{{ PACKAGE_NAME }}/core/router') module.exports = new Router() ``` ## Declare Routes Declare routes using the method corresponding to the HTTP method you want to match. ```js // routes.js const { Router } = require('{{ PACKAGE_NAME }}/core/router') module.exports = new Router().get('/some-path', ({ cache, proxy }) => { // handle the request here }) ``` All HTTP methods are available: - get - put - post - patch - delete - head To match all methods, use `match`: ```js // routes.js const { Router } = require('{{ PACKAGE_NAME }}/core/router') module.exports = new Router().match('/some-path', ({ cache, proxy }) => { // handle the request here }) ``` ## Route Execution When {{ PRODUCT_NAME }} receives a request, it executes **each route that matches the request** in the order in which they are declared until one sends a response. The following methods return a response: - [appShell](/docs/api/core/classes/_router_responsewriter_.responsewriter.html#appshell) - [compute](/docs/api/core/classes/_router_responsewriter_.responsewriter.html#compute) - [proxy](/docs/api/core/classes/_router_responsewriter_.responsewriter.html#proxy) - [redirect](/docs/api/core/classes/_router_responsewriter_.responsewriter.html#redirect) - [send](/docs/api/core/classes/_router_responsewriter_.responsewriter.html#send) - [serveStatic](/docs/api/core/classes/_router_responsewriter_.responsewriter.html#servestatic) - [serviceWorker](/docs/api/core/classes/_router_responsewriter_.responsewriter.html#serviceworker) - [stream](/docs/api/core/classes/_router_responsewriter_.responsewriter.html#stream) - [use](/docs/api/core/classes/_router_responsewriter_.responsewriter.html#compute) Multiple routes can therefore be executed for a given request. A common pattern is to add caching with one route and render the response with a later one using middleware. In the following example we cache then render a response with Next.js: ```js const { Router } = require('{{ PACKAGE_NAME }}/core/router') const { nextRoutes } = require('{{ PACKAGE_NAME }}/next') // In this example a request to /products/1 will be cached by the first route, then served by the `nextRoutes` middleware new Router() .get('/products/:id', ({ cache }) => { cache({ edge: { maxAgeSeconds: 60 * 60, staleWhileRevalidateSeconds: 60 * 60 }, }) }) .use(nextRoutes) ``` ### Alter Requests and Responses {{ PRODUCT_NAME }} offers APIs to manipulate request and response headers and cookies. The APIs are: | Operation | Request | Upstream Response | Response sent to Browser | | ------------- | --------------------- | ------------------------------ | ------------------------ | | Set header | `setRequestHeader` | `setUpstreamResponseHeader` | `setResponseHeader` | | Add cookie | `*` | `addUpstreamResponseCookie` | `addResponseCookie` | | Update header | `updateRequestHeader` | `updateUpstreamResponseHeader` | `updateResponseHeader` | | Update cookie | `*` | `updateUpstreamResponseCookie` | `updateResponseCookie` | | Remove header | `removeRequestHeader` | `removeUpstreamResponseHeader` | `removeResponseHeader` | | Remove cookie | `*` | `removeUpstreamResponseCookie` | `removeResponseCookie` | `*` Adding, updating, or removing a request cookie can be achieved with `updateRequestHeader` applied to `cookie` header. You can find detailed descriptions of these APIs in the `{{ PACKAGE_NAME }}/core` [documentation](/docs/api/core/classes/_router_responsewriter_.responsewriter.html). #### Embedded Values You can inject values from the request or response into headers or cookies as template literals using the `${value}` format. For example: `setResponseHeader('original-request-path', '${path}')` would add an `original-request-path` response header whose value is the request path. | Value | Embedded value | Description | | --------------- | ---------------------- | ----------------------------------------------------------------------------------------------------------------------------- | | HTTP method | `${method}` | The value of the HTTP method used for the request (e.g. `GET`) | | URL | `${url}` | The complete URL path including any query strings (e.g. `/search?query=docs`). Protocol, hostname, and port are not included. | | Path | `${path}` | The URL path excluding any query strings (e.g. `/search`) | | Query string | `${query:<name>}` | The value of the `<name>` query string or empty if not available. | | Request header | `${req:<name>}` | The value of the `<name>` request header or empty if not available. | | Request cookie | `${req:cookie:<name>}` | The value of the `<name>` cookie in `cookie` request header or empty if not available. | | Response header | `${res:<name>}` | The value of the `<name>` response header or empty if not available. | ## Route Pattern Syntax The syntax for route paths is provided by [path-to-regexp](https://github.com/pillarjs/path-to-regexp#path-to-regexp), which is the same library used by [Express](https://expressjs.com/). ### Named Parameters Named parameters are defined by prefixing a colon to the parameter name (`:foo`). ```js new Router().get('/:foo/:bar', res => { /* ... */ }) ``` **Please note:** Parameter names must use "word characters" (`[A-Za-z0-9_]`). #### Custom Matching Parameters Parameters can have a custom regexp, which overrides the default match (`[^/]+`). For example, you can match digits or names in a path: ```js new Router().get('/icon-:foo(\\d+).png', res => { /* ... */ }) ``` **Tip:** Backslashes need to be escaped with another backslash in JavaScript strings. #### Custom Prefix and Suffix Parameters can be wrapped in `{}` to create custom prefixes or suffixes for your segment: ```js new Router().get('/:attr1?{-:attr2}?{-:attr3}?', res => { /* ... */ }) ``` ### Unnamed Parameters It is possible to write an unnamed parameter that only consists of a regexp. It works the same the named parameter, except it will be numerically indexed: ```js new Router().get('/:foo/(.*)', res => { /* ... */ }) ``` ### Modifiers Modifiers must be placed after the parameter (e.g. `/:foo?`, `/(test)?`, `/:foo(test)?`, or `{-:foo(test)}?`). #### Optional Parameters can be suffixed with a question mark (`?`) to make the parameter optional. ```js new Router().get('/:foo/:bar?', res => { /* ... */ }) ``` **Tip:** The prefix is also optional, escape the prefix `\/` to make it required. #### Zero or More Parameters can be suffixed with an asterisk (`*`) to denote zero or more parameter matches. ```js new Router().get('/:foo*', res => { /* res.params.foo will be an array */ }) ``` The captured parameter value will be provided as an array. #### One or More Parameters can be suffixed with a plus sign (`+`) to denote one or more parameter matches. ```js new Router().get('/:foo+', res => { /* res.params.foo will be an array */ }) ``` The captured parameter value will be provided as an array. ## Matching Method, Query Parameters, Cookies, and Headers Match can either take a URL path, or an object which allows you to match based on method, query parameters, cookies, or request headers: ```js router.match( { path: '/some-path', // value is route-pattern syntax method: /GET|POST/i, // value is a regular expression cookies: { currency: /^(usd)$/i }, // keys are cookie names, values are regular expressions headers: { 'x-moov-device': /^desktop$/i }, // keys are header names, values are regular expressions query: { page: /^(1|2|3)$/ }, // keys are query parameter names, values are regular expressions }, () => {}, ) ``` ## Body Matching for POST requests You can also match HTTP `POST` requests based on their request body content as in the following example: ```js router.match( { body: { parse: 'json', criteria: { operationName: 'GetProducts' } }, // the body content will parsed as JSON and the parsed JSON matched against the presence of the criteria properties (in this case a GraphQL operation named 'GetProducts') }, () => {}, ) ``` Currently the only body content supported is JSON. Body content is parsed as JSON and is matched against the presence of the fields specified in the `criteria` field. The [_POST Body Matching Criteria_](#section_post_body_matching_criteria) section below contains examples of using the `criteria` field. Body matching can be combined with other match parameters such as headers and cookies. For example, ```js router.match( { // Only matches GetProducts operations to the /graphql endpoint // for logged in users path: '/graphql', cookies: { loginStatus: /^(loggedIn)$/i }, // loggedin users body: { parse: 'json', criteria: { operationName: 'GetProducts' } }, }, () => {}, ) ``` ### Caching & POST Body Matching When body matching is combined with `cache` in a route, **the HTTP request body will automatically be used as the cache key.** For example, the code below will cache GraphQL `GetProducts` queries using the entire request body as the cache key: ```js router.match( { body: { parse: 'json', criteria: { operationName: 'GetProducts' } }, }, ({ cache }) => { cache({ edge: { maxAgeSeconds: 60 * 60, staleWhileRevalidateSeconds: 60 * 60 * 24, // this way stale items can still be prefetched }, }) }, ) ``` You can still add additional parameters to the cache key using the normal {{ EDGEJS_LABEL }} `key` property. For example, the code below will cache GraphQL `GetProducts` queries separately for each user based on their userID cookie _and_ the HTTP body of the request. ```js router.match( { body: { parse: 'json', criteria: { operationName: 'GetProducts' } }, }, ({ cache }) => { cache({ edge: { maxAgeSeconds: 60 * 60, staleWhileRevalidateSeconds: 60 * 60 * 24, // this way stale items can still be prefetched }, key: new CustomCacheKey().addCookie('userID'), // Split cache by userID }) }, ) ``` ### POST Body Matching Criteria The `criteria` property can be a string or regular expression. For example, the router below, ```js router.match( { body: { parse: 'json', criteria: { foo: 'bar' } }, }, () => {}, ) ``` would match an HTTP POST request body containing: ```js { "foo": "bar", "bar": "foo" } ``` ### Regular Expression Criteria Regular expressions can also be used as `criteria`. For example, ```js router.match( { body: { parse: 'json', criteria: { operationName: /^Get/ } }, }, () => {}, ) ``` would match an HTTP POST body containing: ```js { "operationName": "GetShops", "query": "...", "variables": {} } ``` ### Nested JSON Criteria You can also use a nested object to match a field at a specific location in the JSON. For example, ```js router.match( { body: { parse: 'json', criteria: { operation: { name: 'GetShops', }, }, }, }, () => {}, ) ``` would match an HTTP POST body containing: ```js { "operation": { "name": "GetShops", "query": "..." } } ``` ## GraphQL Queries The {{ EDGEJS_LABEL }} router provides a `graphqlOperation` method for matching GraphQL. ```js router.graphqlOperation('GetProducts', res => { /* Handle the POST for the GetProducts query specifically */ }) ``` By default, the `graphqlOperation` assumes your GraphQL endpoint is at `/graphql`. You can alter this behavior by using the `path` property as shown below: ```js router.graphqlOperation({ path: '/api/graphql', name: 'GetProducts' }, res => { /* Handle the POST for the GetProducts query specifically */ }) ``` Note that when the `graphqlOperation` function is used, the HTTP request body will automatically be included in the cache key. The `graphqlOperation` function is provided to simplify matching of common GraphQL scenarios. For complex GraphQL matching (such as authenticated data), you can use the generic [_Body Matching for POST requests_](#section_body_matching_for_post_requests) feature. See the guide on [Implementing GraphQL Routing](/guides/graphql) in your project. ## Request Handling The second argument to routes is a function that receives a `ResponseWriter` and uses it to send a response. Using `ResponseWriter` you can: - Proxy a backend configured in `{{ CONFIG_FILE }}` - Serve a static file - Send a redirect - Send a synthetic response - Cache the response at edge and in the browser - Manipulate request and response headers [See the API Docs for Response Writer](/docs/__version__/api/core/classes/_router_responsewriter_.responsewriter.html) ## Full Example This example shows typical usage of `{{ PACKAGE_NAME }}/core`, including serving a service worker, next.js routes (vanity and conventional routes), and falling back to a legacy backend. ```js // routes.js const { Router } = require('{{ PACKAGE_NAME }}/core/router') module.exports = new Router() .get('/service-worker.js', ({ serviceWorker }) => { // serve the service worker built by webpack serviceWorker('dist/service-worker.js') }) .get('/p/:productId', ({ cache }) => { // cache products for one hour at edge and using the service worker cache({ edge: { maxAgeSeconds: 60 * 60, staleWhileRevalidateSeconds: 60 * 60, }, browser: { maxAgeSeconds: 0, serviceWorkerSeconds: 60 * 60, }, }) proxy('origin') }) .fallback(({ proxy }) => { // serve all unmatched URLs from the origin backend configured in {{ CONFIG_FILE }} proxy('origin') }) ``` ## Errors Handling You can use the router's `catch` method to return specific content when the request results in an error status (For example, a 500). Using `catch`, you can also alter the `statusCode` and `response` on the edge before issuing a response to the user. ```js router.catch(number | Regexp, (routeHandler: Function)) ``` ### Examples To issue a custom error page when the origin returns a 500: ```js // routes.js const { Router } = require('{{ PACKAGE_NAME }}/core/router') module.exports = new Router() // Example route .get('/failing-route', ({ proxy }) => { proxy('broken-origin') }) // So let's assume that backend "broken-origin" returns 500, so instead // of rendering the broken-origin response we can alter that by specifing .catch .catch(500, ({ serveStatic }) => { serveStatic('static/broken-origin-500-page.html', { statusCode: 502, }) }) ``` The `.catch` method allows the edge router to render a response based on the result preceeding routes. So in the example above whenever we receive a 500 we respond with `broken-origin-500-page.html` from the application's `static` directory and change the status code to 502. - Your catch callback is provided a [ResponseWriter](/docs/api/core/classes/_router_responsewriter_.responsewriter.html) instance. You can use any ResponseWriter method except `proxy` inside `.catch`. - We highly recommend keeping `catch` routes simple. Serve responses using `serveStatic` instead of `send` to minimize the size of the edge bundle. ## Environment Edge Redirects In addition to sending redirects at the edge within the router configuration, this can also be configured at the environment level within the Layer0 Developer Console. Under _<Your Environment> → Configuration_, click _Edit_ to draft a new configuration. Scroll down to the _Redirects_ section:  Click _Add A Redirect_ to configure the path or host you wish to redirect to:  **Note:** you will need to activate and redeploy your site for this change to take effect.
