Routing

See the routing's concept for details.

How to create a route?

You have to edit the routes.json file in one of your APIs folders (./api/**/config/routes.json) and manually add a new route object into the routes array.

Path — ./api/**/config/routes.json.

{
  "routes": [
    {
      "method": "GET",
      "path": "/product",
      "handler": "Product.find",
    },
    {
      "method": ["POST", "PUT"],
      "path": "/product/:id",
      "handler": "Product.createOrUpdate",
    },
    {
      "method": "POST",
      "path": "/product/:id/buy",
      "handler": "Product.buy",
      "config": {
        "policies": ["isAuthenticated", "hasCreditCard"]
      }
    }
  ]
}

• method (string): Method or array of methods to hit the route (ex: GET, POST, PUT, HEAD, DELETE, PATCH)
• path (string): URL starting with / (ex: /product)
• handler (string): Action to executed when the route is hit following this syntax <Controller>.<action>
• config
  • policies (array): Array of policies names or path (see more)
  • prefix (string): Set a prefix to this route. Also, it will be loaded into the main router (useful feature for plugin)

Dynamic parameters

The router used by Strapi allows you to create dynamic routes where you can use parameters and simple regular expressions. These parameters will be exposed in the ctx.params object. For more details, please refer to the PathToRegex documentation.

{
  "routes": [
    {
      "method": "GET",
      "path": "/product/:category/:id",
      "handler": "Product.findOneByCategory",
    },
    {
      "method": "GET",
      "path": "/product/:region(\\d{2}|\\d{3})/:id", // Only match when the first parameter contains 2 or 3 digits.
      "handler": "Product.findOneByRegion",
    }
  ]
}

Override default route

By default, the main route of the server / is pointed to the /public/index.html file. To override this behavior, you need to create a route with an empty path / in one of your API folder (/api/**/config/routes.json).

{
  "routes": [
    {
      "method": "GET",
      "path": "/",
      "handler": "Controller.name",
    }
  ]
}
