海外TECH	DEV Community	Use ALL the Features: How To Create a Fancy Password Input With Vue3 🔑✅	https://dev.to/thormeier/use-all-the-features-how-to-create-a-fancy-password-input-with-vue3-ggi	Use ALL the Features How To Create a Fancy Password Input With Vue Vue has brought us a ton of fancy new features The composition API lets us create components in a more intuitive JS y way there is now support for multiple v model directives full TypesSript support out of the box and the reactivity improved a lot when compared to Vue Today we ll put these things to use to create a fancy password input component One that lets us define password requirements and informs the outer component and the user about the password validity and the password The basisFirst we create a new Vue component called PasswordInput vue In there we add some template an amepty script tag and some styling lt template gt lt div class password input gt lt label for password gt Enter password lt label gt lt We ll add stuff to this input later gt lt input type password id password gt lt button gt Show password lt button gt lt label for password repeat gt Repeat password lt label gt lt We ll add stuff to this input later gt lt input type password id password repeat gt lt ul class requirements gt lt Add requirements here gt lt ul gt lt div gt lt template gt lt script setup lang ts gt lt script gt lt style scoped gt password input display flex flex direction column label margin bottom px font size px input margin bottom px padding px font size px button margin bottom px requirements font weight bold is success color CAD is error color BA lt style gt We added two input fields for password and password repeat a button that will show and hide the password as well as an unordered list for the password requirements that we ll add later Notice how we re using lt script setup lang ts gt to tell Vue that we want to use the composition API for the entire component The styling already includes classes for success and failure The rest is rather rudimentary When we use the component we should see something like this Hooking up the fieldsLet s add two refs for the password and password repeat We also add a flag to determine if the password is currently shown or not While we re at it we also import computed and watch because we ll use that later For that we add the following to the script tag import computed ref watch from vue const password ref const passwordRepeat ref const showPassword ref false We can now hook these up with the template lt gt lt label for password gt Enter password lt label gt lt input type showPassword text password v model password change emit update password event target value id password gt lt button click showPassword showPassword gt showPassword Hide password Show password lt button gt lt label for password repeat gt Repeat password lt label gt lt input type showPassword text password v model passwordRepeat id password repeat gt lt gt Adding the requirementsNow comes the fun part We want to validate the password with the following requirements It should be at least characters longIt should contain at least one uppercase letterIt should contain at least one lowercase letterIt should contain at least one symbolIt should contain at least one numberIt must match the Repeat password fieldTo get Vue s reactivity in we can create a computed value that checks the password ref for all fo these const passwordRequirements computed gt name Must contain uppercase letters predicate password value toLowerCase password value name Must contain lowercase letters predicate password value toUpperCase password value name Must contain numbers predicate d test password value name Must contain symbols predicate W test password value name Must be at least characters long predicate password value length gt name Must match predicate password value passwordRepeat value Using an array of requirements has several advantages We can extend it whenever we likeRendering it is trivial with a v for loopWe can reuse the predicates and move them to a utils file or use them in a state management systemLet s render the requirements in the list lt gt lt ul class requirements gt lt li v for requirement key in passwordRequirements key key class requirement predicate is success is error gt requirement name lt li gt lt ul gt lt gt Now whenever the user changes either one of the values the requirements are recalculated and updated in the template giving feedback to the user directly We should now see something like this So far so good Emitting changes and usageWe now want to make the component usable For that we need to emit changes Since Vue now allows to have multiple v model directives on a component we can emit different events in case of changes to either password field For that we add change event listeners to the password input fields lt gt lt input type showPassword text password v model password change emit update password event target value id password gt lt gt lt input type showPassword text password v model passwordRepeat change emit update passwordRepeat event target value id password repeat gt lt gt We then also want to emit if the password is valid or not so a single boolean value We use a watch for that that will watch the passwordRequirements compured value and emit a single boolean const emit defineEmits update password update passwordRepeat update validity watch passwordRequirements gt emit update validity passwordRequirements value reduce v p gt v amp amp p predicate true And done The component now emits changes for the password the password repeat field and the password validity It also shows the user direct visual feedback about the password s validity and let s them show or hide the password to see if they perhaps mistyped We can now use the component as follows in any template lt template gt lt gt lt PasswordInput v model password password v model password repeat passwordRepeat v model validity isPasswordValid gt lt gt lt template gt Awesome To learn more about Vue and its advanced features I recently published a course on Educative io called Advanced VueJS Build Better Applications Efficiently In lessons you can learn about all kinds of features such as custom events advanced templating how to use APIs In or slots and hooks You can find the course over on Educative io I hope you
