getChildRoutes dynamically












0















In react-router examples, have following code for dynamic load children, but I want to dynamic calculate the dependencies. However, it seems NOT work. forEach loop will throw error, says "Cannot find module xxx"



getChildRoutes(location, callback) {
require.ensure(, function (require) {
callback(null, [
require('./routes/Announcements'),
require('./routes/Assignments')
])
})
},


----###############################################----



getChildRoutes(location, callback) {
require.ensure(, function (require) {
var appsRoutes = ['routes/Announcements', 'routes/Assignments'].forEach(item=>{
return require('./' + item);
});
callback(null, appRoutes)
})
},

          Does the following variation work?



          const dynamicRoutes = [
          './routes/Announcements',
          './routes/Assignments'
          ];

          ...

          getChildRoutes(location, callback) {
          require.ensure(dynamicRoutes, function (require) {
          var appsRoutes = dynamicRoutes.map(item => require(item));
          callback(null, appRoutes);
          });
          },


          I think webpack needs to be able to calculate which modules to create dynamic hooks on to during compile time, which it isn't able to resolve due to your concat forEach loop approach.



          This alternative could possibly work too:



           getChildRoutes(location, callback) {
          require.ensure(, function (require) {
          var appsRoutes = [
          require('./routes/Announcements'),
          require('./routes/Assignments')
          ];
          callback(null, appRoutes);
          });
          },

          • in fact, the appRoutes is calculated dynamic, something like var config = ['Annoucements', 'Assignments']; appRoutes = config.map(item=>{return './routes/' + item})

          • Do you mean that the config array (i.e. var config = ['Announcements', 'Assignments']) is mutated at run time? So you could for example during another route resolution have a variable of var config = ['Announcements', 'Assignments', 'Foo']). i.e. values get appended/removed from the array during run time?
