Jest tests can’t process import statement in vuejs vue-cli

Explanation of the problem

The problem is related to setting the “abortEarly” option for the Yup validation library. The goal is to have a password field with multiple errors displayed. The validateSchema() method does not seem to provide this functionality.

To achieve this, the following code is being used:

validate: (values) => {
    const schema = Yup.object().shape({
      email: Yup.string()
        .matches(/georges.abitbol@gmail.com/, 'cant change email'),
      providerName: Yup.string()
        .required('type your name'),
      password: Yup.string()
        .min(8, 'at least 8 chars')
        .matches(/[a-z]/, 'at least one lowercase char')
        .matches(/[A-Z]/, 'at least one uppercase char')
        .matches(/[a-zA-Z]+[^a-zA-Z\s]+/, 'at least 1 number or special char (@,!,#, etc).'),
      passwordConfirm: Yup.string()
        .equalTo(Yup.ref('password'), 'passwords don\'t match')
    })

    return schema.validate(values, { abortEarly: false })
      .then(() => {})
      .catch((err) => {
        throw err
      })
  }

This allows for the retrieval of every error of a single field and mapping them to the relevant components for display. However, the developer is seeking a cleaner solution to this problem and suggests that it could be a good use case to showcase.

Problem solution for yup schema.validate() options, show every error of a field at the same time

Troubleshooting the issue of displaying every error of a field at the same time with the Yup schema.validate() options requires a few key steps.

First, it is important to ensure that the “abortEarly” option is set to “false” in the validate method, as this will prevent the validation process from stopping at the first error found.

return schema.validate(values, { abortEarly: false })

Additionally, it is important to properly handle the validation errors that are thrown. This can be done by using the catch() method after the validate method and throwing the error.

.catch((err) => {
    throw err
  })

It is also possible to map the errors to the relevant components for display using the error.inner property which is an array of ValidationError objects.

.catch((err) => {
    err.inner.forEach(error => {
      console.log(error.path, error.message)
    })
    throw err
  })

It is important to test the validation with different inputs to ensure that all the errors are captured and displayed correctly.

By following these steps and properly handling the errors, it is possible to display every error of a field at the same time with the Yup schema.validate() options.

Problem: Incorrect Webpack Configuration

One of the most common issues with vue-cli is incorrect Webpack configuration. This can manifest in a variety of ways, such as missing loaders or plugins, or misconfigured output paths. This can result in build errors or unexpected behavior in the application.

Solution:

To resolve this issue, it is necessary to review the Webpack configuration in the vue.config.js file and ensure that all necessary loaders and plugins are included, and that the output paths are configured correctly. Additionally, checking the version of Webpack and ensuring that it is compatible with the version of vue-cli being used can also help resolve this issue.

Problem: Incorrect Use of Vue Router

Another common issue with vue-cli is incorrect use of the Vue Router. This can manifest in a variety of ways, such as missing routes or misconfigured redirects. This can result in broken links or unexpected behavior in the application.

Solution:

To resolve this issue, it is necessary to review the Vue Router configuration in the router.js file and ensure that all necessary routes are included and configured correctly. Additionally, checking the version of Vue Router and ensuring that it is compatible with the version of vue-cli being used can also help resolve this issue.

Problem: Incorrect Use of Vuex

One more common issue with vue-cli is incorrect use of the Vuex. This can manifest in a variety of ways, such as missing state or misconfigured actions. This can result in unexpected behavior in the application.

Solution:

To resolve this issue, it is necessary to review the Vuex configuration in the store.js file and ensure that all necessary state and actions are included and configured correctly. Additionally, checking the version of Vuex and ensuring that it is compatible with the version of vue-cli being used can also help resolve this issue.

A brief introduction to vuejs vue-cli

­

Vue-cli is a command-line interface (CLI) tool for scaffolding Vue.js projects. It allows developers to quickly set up a new Vue.js project with a structure that follows best practices and includes a variety of features, such as a development server, a build pipeline, and testing utilities. Vue-cli uses a template-based approach, where developers can choose from a variety of pre-configured templates or create their own custom templates.

Vue-cli provides a variety of features to help developers quickly set up and configure their Vue.js projects. For example, it includes a development server that allows developers to run their application locally and see changes in real-time. Additionally, it includes a build pipeline that allows developers to optimize and minify their application for production use. It also includes testing utilities that allow developers to write and run unit tests on their application. Vue-cli also provides a plugin system, which allows developers to add additional features to their project, such as a CSS preprocessor or a linter, by installing and configuring plugins. By using vue-cli developers can easily manage their project dependencies, assets, and configurations.

Some popular applications of vue-cli include

1. Form management: One of the primary uses of Formik is to manage forms. It provides a set of methods and props that make it easy to handle form submissions, form field updates, and form validation. Formik also makes it easy to keep track of form state and display errors to the user.
2. Simplifying form logic: Formik simplifies form logic by abstracting away the complexities of handling form field updates and validation. This allows developers to focus on the business logic and user experience of their forms without having to worry about the underlying implementation.
3. Integrating with other libraries: Formik can be easily integrated with other libraries such as Yup for form validation and React Router for navigation. This allows developers to leverage the benefits of Formik with other libraries they are already using, making it easy to add forms to existing applications.
