Development Vue or React Project time path alias intelligent prompt scheme


In our development Vue or React Project time , After each configuration path alias , There is no corresponding intelligent prompt path when inputting the path , How to solve this pain point ?

I usually use vscode, This use vscode To demonstrate and solve , Very simple

Scheme 1 : path-alias plug-in unit

As the saying goes 「 A good workman does his work well , You must sharpen your tools first 」 that Is there a plug-in that allows us to input path aliases in different projects , There are relevant path tips ?

The answer is : Of course some , And almost zero configuration , Now let's take a look at

No effect installed

  • No path alias smart tip ,vscode By default, the path alias you configured cannot be recognized

Installation effect and function

  • stay vscode Search and install in the plug-in mall : path-alias
  • It's not just the road Path alias smart tip , just so so Click the alias path to jump to the file
  • Take a look at the function demonstration below

  • and Support importing function or variable from alias , There's a related smart tip

Selective configuration

  • Before being elected, we said zero configuration , Why are you so ready to face ?
  • Don't worry don't worry , Listen to me , It is said that .., Well, don't smack in the face
  • Return to the right topic : because path-alias Plug in only default configuration path @ Mapping to project src Catalog

    • When you need to have more path aliases with corresponding mappings, there are smart tips , It can only be configured , It's also very simple , Don't panic
    • Get into your vscode Of settings.json file

      • If you don't know settings.json Where is the file? Right plug-in key to enter the settings , As shown in the figure
  • Add the following

// When you use path aliases when developing a project, there will be " Smart tips "
"pathAlias.aliasMap": {
// key It's the alias you want to define | Use ${cwd} To replace the absolute path of the current working directory
"@": "${cwd}/src",
"~": "${cwd}/src",
"components": "${cwd}/src/components"

  • At this point, the path input component There will also be smart tips

 Path alias smart tip

A little bit of weakness
  • Of course, there is no perfect plug-in , Weakness is : It takes up a little bit of memory , The author is also maintaining recently
  • This mainly depends on whether the user's experience is proportional to the occupation of memory , Of course, if you don't want to configure every new project jsconfig.json or tsconfig.json The alias path of intelligent prompt words , It is recommended to use this plug-in directly
  • Of course, if you think the memory is too high , It is recommended to use jsconfig.json, That's plan two

Option two : jsconfig


  • Create a new one in the root of your project : jsconfig.ison file
  • Small memory recommended , Copy the following to your file , again vscode that will do

"compilerOptions": {
"experimentalDecorators": true,
"baseUrl": "./",
"paths": {
"@/": ["src/"],
"components/": ["src/components/"],
"assets/": ["src/assets/"],
"views/": ["src/views/"],
"common/": ["src/common/"],
"exclude": ["node_modules", "dist"]

To sum up

  • If you want to configure it once and don't care about memory usage , Recommended direct use path-alias plug-in unit
  • If you don't have enough memory or feel the plug-in experience is poor , It is recommended to use jsconfig.json
