Upon building & packaging an Angular 6 library, I can't seem to be able to instruct the Angular CLI to copy the library's assets into the dist/assets
folder on every build.
Assuming the project's folder structure is this -
- dist
- e2e
- node_modules
- projects
- lib1
- src
- lib
- assets
- icons
- src
When I run ng build lib1
or ng build lib1 --prod
the assets/icons
folder is not being copied into dist/lib1/assets/icons
.
If I run ng build
then src/assets
(the root src/assets) is being copied but not projects/lib1/assets
.
The angular.json
file contains a reference to "assets": ["src/assets"]
but it won't allow adding the assets
key specifically to the project, only to the main root app. When adding, I get the following error:
Schema validation failed with the following errors: Data path "" should NOT have additional properties(assets).
I also tried adding the following custom copy rule to the assets to copy the assets to dist/lib instead of to dist/appname:
"assets": [
"src/favicon.ico",
"src/assets",
{ "glob": "**/*", "input": "src/assets/icons", "output": "../lib1/assets/icons" }
],
But I get the following error:
An asset cannot be written to a location outside of the output path.
Is there a built-in way of managing library asset's copy on every build?
UPDATE 06/05/2018
I opened an issue with Angular CLI regarding this but have not heard back yet. Issue #11701
Currently, I still have not found an official built-in way to do so.
I opened an Angular CLI issue and hopefully will get the CLI team response.
In the meantime my workaround is using command line tools:
In package.json
I added:
"scripts": {
...
"build": "ng build lib1 --prod && scss-bundle -c scss-bundle.config.json && cp -R projects/lib1/src/assets/ dist/lib1/assets/",
}
To copy the SASS files I use scss-bundle
with config file scss-bundle.config.json
that contains:
{
"entry": "./projects/lib1/src/assets/style/main.scss",
"dest": "./dist/lib1/assets/style/styles.scss"
}
This will build the SASS files of the project into 1 file and copy it into the dist folder. My SASS file structure is something like:
-- projects/lib1/src/assets/
-- style
-- main.scss
-- partials
-- _variables.scss
-- _styles.scss
__ _rtl.scss
So as you can see I don't want to ship all the raw sass, just one final file. Of course, you can also compile it into a .css
file instead.
To make sure all other assets are copied, I use a simple Mac OS/Linux command cp -R
or rsync
.
And, of course, instead of running ng build
I run npm run build
.
Hope this helps, and if you have a better solution please let me know.
