自动从同一目录导入

Question

I have this file, which imports and mounts routes from components/* directory.

Is there any way I could automate this?

// Middlewares
const authorizeMiddleware = require('../middlewares/authorize');
const authMiddleware = require('../middlewares/auth');

// load components
const aclComponent = require('../components/acl/acl.component');
const jobComponent = require('../components/job/job.component');
const zoneComponent = require('../components/zone/zone.component');
const authComponent = require('../components/auth/auth.component');
const cityComponent = require('../components/city/city.component');
const usersComponent = require('../components/user/user.component');
..
...
.....

function loadRoutes(router) {
  router.use(
    '/auth',
    authComponent.AuthRoutes,
  );

  router.use(
    '/users',
    usersComponent.UsersRoutes,
  );
  
  ..
  ...
  ....
  return router;
}

module.exports = loadRoutes;

I have seen such things in typeorm where it search for entities based on patterns.

Something similar to this,

{
  "entities": ["dist/entity/**/*.js"],
  "migrations": ["dist/migration/**/*.js"],
  "subscribers": ["dist/subscriber/**/*.js"],
  "cli": {
    "entitiesDir": "src/entity",
    "migrationsDir": "src/migration",
    "subscribersDir": "src/subscriber"
  }

Can this be achieved with this package ?

I tried glob.js and it did the work,

const glob = require('glob');
const path = require('path');

// Use the glob package to match all files ending in ".component.js" in the "components" directory
const componentFiles = glob.sync(path.join(__dirname, 'components', '**', '*.component.js'));

function loadRoutes(router) {
  // Iterate over the matched files and require each one
  componentFiles.forEach((componentFile) => {
    const component = require(componentFile);

    // Extract the component name from the file name (e.g. "acl.component.js" => "acl")
    const componentName = path.basename(componentFile, '.component.js');

    // Mount the routes for the component on the router using the component name as the base path
    router.use(`/${componentName}`, component.Routes);
  });

  return router;
}

module.exports = loadRoutes;
