How to remove strict mode in Vue project

Vue is a popular JavaScript framework for developing dynamic, responsive web applications. Vue has strict mode enabled by default to make it easier to catch potential bugs during development. However, in some cases, it may be necessary to temporarily turn off strict mode. This article will discuss how to remove strict mode in Vue applications.

What is strict mode?

In Vue, strict mode is a development mode that enforces some Vue code rules and increases the verbosity of error messages. Strict mode helps developers avoid using unsafe behaviors in applications and helps detect potential bugs.

Some rules for strict mode include:

• Duplicate property names are not allowed in component definitions
• Undefined properties are not allowed in component definitions Name
• Props used in component definitions must be defined in prop declarations

If the application violates the rules therein, Vue will give detailed error messages during development , so that developers can quickly resolve these issues.

Why should we remove strict mode?

Although strict mode can help you write safer and more reliable Vue code, it may interfere with the development process in some cases. For example:

• During the development process, you may use incomplete component definitions because some information needs to be provided using other features such as plug-ins.
• You may use different Vue instances to load components, plug-ins, etc. from different modules, which may result in different runtime behaviors.
• You may need to use some special global functions or properties in Vue, which may not work properly in strict mode.

In these cases, it may be more convenient and flexible to disable strict mode.

How to remove strict mode?

To disable strict mode in Vue, you can set the strict property to false in the Vue instance. For example:

var app = new Vue({
  strict: false,
  // ...
})

The default value of this property is true, which means that Vue has strict mode enabled by default.

You can also disable strict mode by setting a global default in the Vue constructor. For example:

Vue.config.strict = false

This will disable strict mode in all Vue instances.

If you only want to disable strict mode in a certain component, you can set the strict attribute in the options of that component. For example:

var myComponent = Vue.extend({
  strict: false,
  // ...
})

Summary

Strict mode is a development mode of Vue, which can improve the reliability and security of the code, but may cause trouble for some applications and scenarios . In order to disable strict mode, you can set the strict property of the Vue instance, or set a global default in the Vue constructor. If you only want to disable strict mode for a specific component, you can set the strict property in that component's options.
