QUESTION
I need help debugging Webpack's Compression Plugin.
SUMMARY OF PROBLEM
- Goal is to enable asset compression and reduce my app's bundle size. Using the Brotli algorithm as the default, and gzip as a fallback for unsupported browsers.
- I expected a content-encoding field within an asset's Response Headers. Instead, they're loaded without the field. I used the Chrome dev tools' network tab to confirm this. For context, see the following snippet:
- No errors show in my browser or IDE when running locally.
WHAT I TRIED
- Using different implementations for the compression plugin. See below list of approaches:
- (With Webpack Chain API)
ANSWER
Answered 2021-Sep-30 at 14:59It's not clear which server is serving up these assets. If it's Express, looking at the screenshot with the header X-Powered-By, https://github.com/expressjs/compression/issues/71 shows that Brotli support hasn't been added to Express yet.
There might be a way to just specify the header for content-encoding manually though.

QUESTION
After updating my npm packages, some of the imports from the 'vue' module started showing errors:
TS2305: Module '"../../node_modules/vue/dist/vue"' has no exported member 'X'
where X is nextTick, onMounted, ref, watch etc. When serving the project, Vue says it's "failed to compile". WebStorm actually recognizes the exports, suggests them and shows types, but the error is shown regardless. Some exports like computed and defineComponent work just fine.
What I've tried:
- Rollback to the previously used Vue version "3.2.2" > "3.0.11". It makes the abovementioned type errors disappear, but the app stops working entirely, showing lots of
TypeError: Object(...) is not a functionerrors in console and not rendering the app at all. In the terminal, some new warnings are introduced:"export 'X' (imported as '_X') was not found in 'vue'where X is createElementBlock, createElementVNode, normalizeClass and normalizeStyle. - Rollback other dependencies. None of the ones that I tried helped fix the problem, unfortunately.
- Manually declare the entirety of 'vue' module. We can declare the 'vue' module exports in shims-vue.d.ts, and it actually makes the errors disappear, however, this seems like a terrible, time-consuming workaround, so I would opt out for a better solution if possible.
My full list of dependencies:
...ANSWER
Answered 2021-Aug-15 at 13:53That named exports from composition API are unavailable means that vue is Vue 2 at some place which has only default export. Since Vue 3 is in dependencies and both lock file and node_modules were refreshed, this means that Vue 2 is nested dependency of some direct dependency.
The problem needs to be investigated in lock file. It shows that @vue/cli-plugin-unit-jest@4.5.13 depends on vue-jest@3 which depends on vue@2.
A possible solution is to upgrade @vue/cli-plugin-unit-jest to the latest version, next. The same likely applies to other @vue/cli-* packages because they have matching versions.

Answered 2021-Dec-07 at 08:54It seems that you have problems with peer dependencies, if you just set your npm to use legacy dependency logic to install your packages you will solve the problem.
Just add to your Dockerfile this setting before running npm install:

QUESTION
I am developing a Drawflow application using Vuejs/Nuxtjs based on the code mentioned here. When I install the package element-plus and start the application then I get the error:
ANSWER
Answered 2021-Nov-21 at 17:22Element+ is a Vue3 UI library, so it is indeed not compatible with Nuxt2 (using Vue2). Hence why you're getting the error: it is not retro-compatible with Vue2.
Meanwhile, Element is totally compatible with Vue2 and may be a good-enough fit.
Do you need to use exactly this one btw? There is a lot of choices when it comes down to CSS frameworks compatible with both Vue2 and Vue3. Not all of them are, but most do.
