The difference between params and query parameters in vue

In Vue, params is used to pass required dynamic data (such as:id in /users/:id), which is accessed in $route.params and is often used to pass required parameters such as specific IDs; query is used Pass optional additional data (such as /users?name=John&age=30), accessed in $route.query, often used to pass optional options such as filters.

The difference between params and query parameters in Vue

Get straight to the point

In Vue, params and query are two ways to pass data between routes, but they are different in purpose and behavior.

Detailed expansion

params

• is used to pass dynamic data that must be included in the URL.
• Exists as part of the routing path, such as :id in /users/:id.
• Accessed in $route.params.
• Mainly used to pass required parameters such as the ID of a specific resource or entity.

query

• is used to pass optional data appended to the query string in the URL.
• Suffix the URL with the ? delimiter, for example /users?name=John&age=30.
• Accessed in $route.query.
• Usually used to pass filters, sorting or other optional options.

Other differences

• URL format: params appears in the path, and query appears in the query string.
• Required fields: params is usually required, while query is optional.
• Server-side access: params can be accessed by the backend server, while query may not.
• Variability: params are lost after form submission or redirect, while query remains in the URL.

Which method to choose

Whether to use params or query depends on the purpose and nature of the data passed:

• Required data: Use params to pass data that must be included in the URL.
• Optional data: Use query to pass optional data appended to the URL.
• Server-side access: Use params if you need to access data on the backend server.
• Variability: Use query if data needs to be retained after form submission or redirection.
