I have application structure like this:
1. app
1. Shared Module
2. Modules
1. ExternalSourceModule
Child Modules
1. SourceModule
2. EntityModule
ExternalSourceSharedModule
1. `ExternalSourceSharedModule` imports `SharedModule` because shared
module has application level dependencies
2. `ExternalSourceModule` and it child modules imports
`ExternalSourceSharedModule` because `ExternalSourceSharedModule` has some
dependencies which `ExternalSourceModule` and it's `Child Modules Needs`
Code of `ExternalSourceSharedModule`:
@NgModule({
...
imports: [
ShareModule,
]
...
});
Code of `ExternalSourceModule` which imports `ExternalSourceSharedModule`
@NgModule({
...
imports: [
ExternalSourceSharedModule,
RouterModule.forChild(externalSourceRoutes)
],
...
});
Now `ExternalSourceModule` Lazy Loads it's child Module:
export const externalSourceRoutes: Routes = [
{ path: 'source', loadChildren:
'./modules/source/source.module#SourceModule' },
{ path: 'entity', loadChildren:
'./modules/entity/entity.module#EntityModule' }
]
`ExternalSourceSharedModule` has dependencies for `ExternalSourceModule` as
well as `SourceModule` and `EntityModule` So i've to import that
`ExternalSourceSharedModule` in `SourceModule` and `EntityModule` as well
code:
`EntityModule:`
@NgModule({
...
imports: [
ExternalSourceSharedModule
RouterModule.forChild(entityRoutes)
],
...
});
export class EntityModule {}
`SourceModule:`
@NgModule({
...
imports: [
ExternalSourceSharedModule
RouterModule.forChild(entityRoutes)
],
...
});
export class SourceModule {}
I'm using `@angular/cli` for my project, Doing `ng build` returns this:
Time: 9020ms
chunk {0} 0.chunk.js, 0.chunk.js.map 1.17 MB {1} {2} {3} {4} {5} {6}

chunk {4} 4.chunk.js, 4.chunk.js.map 1.18 MB {0} {1} {2} {3} {5} {6}

chunk {5} 5.chunk.js, 5.chunk.js.map 5.29 kB {0} {1} {2} {3} {4} {6}
{9}
chunk {6} 6.chunk.js, 6.chunk.js.map 11.8 kB {0} {1} {2} {3} {4} {5}
{9}
chunk {7} polyfills.bundle.js, polyfills.bundle.js.map (polyfills)
158 kB {11} [initial]
chunk {8} styles.bundle.js, styles.bundle.js.map (styles) 256 kB
{11} [initial]
chunk {9} main.bundle.js, main.bundle.js.map (main) 122 kB {10}
[initial] [rendered]
chunk {10} vendor.bundle.js, vendor.bundle.js.map (vendor) 4.58 MB
[initial] [rendered]
chunk {11} inline.bundle.js, inline.bundle.js.map (inline) 0 bytes
[entry]
Let assume:
- 1.chunk.js is `ExternalSourceModule`
- 0.chunk.js is `EntityModule` which is a child of `ExternalSourceModule`
- 3.chunk.js is `SourceModule` which is a child of `ExternalSourceModule`
You can see the size of these chunks which has > 1 MB now when i remove
`ExternalSourceSharedModule` from `EntityModule` and `SourceModule` then
doing `ng build` returns:
Time: 8779ms
chunk {0} 0.chunk.js, 0.chunk.js.map 84.3 kB {1} {2} {3} {4} {5} {6}
{9} [rendered]
chunk {1} 1.chunk.js, 1.chunk.js.map 1.19 MB {0} {2} {3} {4} {5} {6}
{9} [rendered]
chunk {2} 2.chunk.js, 2.chunk.js.map 394 kB {0} {1} {3} {4} {5} {6}
{9} [rendered]
chunk {3} 3.chunk.js, 3.chunk.js.map 355 kB {0} {1} {2} {4} {5} {6}
{9} [rendered]
chunk {4} 4.chunk.js, 4.chunk.js.map 89.3 kB {0} {1} {2} {3} {5} {6}
{9} [rendered]
chunk {5} 5.chunk.js, 5.chunk.js.map 5.29 kB {0} {1} {2} {3} {4} {6}
{9}
chunk {6} 6.chunk.js, 6.chunk.js.map 11.8 kB {0} {1} {2} {3} {4} {5}
{9}
chunk {7} polyfills.bundle.js, polyfills.bundle.js.map (polyfills)
158 kB {11} [initial]
chunk {8} styles.bundle.js, styles.bundle.js.map (styles) 256 kB
{11} [initial]
chunk {9} main.bundle.js, main.bundle.js.map (main) 122 kB {10}
[initial] [rendered]
chunk {10} vendor.bundle.js, vendor.bundle.js.map (vendor) 4.58 MB
[initial] [rendered]
chunk {11} inline.bundle.js, inline.bundle.js.map (inline) 0 bytes
[entry]
Now if you see the sizes of chunks reduces to below < 1 MB so the questions
becomes is there is any technique where i can tell to
`ExternalSourceModule` that use `ExternalSourceSharedModule` for it's child
modules as well, so that i don't need to import
`ExternalSourceSharedModule` in child modules.
Currently removing `ExternalSourceSharedModule` from child modules breaks
my application.
Hope i have cleared my questions.
