Currently most of doccano's Javascript is in webpack bundles, except for
a few snippets like swiper. To increase consistency, this change moves
the swiper code also into a webpack bundle.
In addition to increasing consistency, this also has the advantages of:
1) Giving developers a single location/directory to look for all the
Javascript.
2) Making the swiper dependency explicit by listing it in the
package.json manifest
3) Ensuring that swiper gets built and minified in the same way as other
dependencies.
4) Making swiper available when developing offline.
In the future, it would also be worth considering to move all the CSS
includes into webpack.
Note that the linter acts on Vue components in both `.js` and `.vue`
files.
To keep the changes minimal and targeted, for now the linter uses a very
permissive rule-set which essentially means that the linter is mostly
disabled. As a separate change, we should fix all the lint issues and
tighten the rule-set to `plugin:vue/recommended`.
Currently Django and Vue are somewhat coupled in that the project
intermixes templating constructs from both eco-systems.
Examples of this in `projects.html` include:
- Checking if the user is a superuser to modify the Vue template.
- Using Django filters to inject the capitalized username.
This makes it somewhat hard to follow the Vue code and also makes it
more difficult to modularize the Vue components and re-use them.
As such, this change improves the separation of concerns by having the
Django template only scafold the root element for Vue and serialize any
variables that are required from the Django context to Javascript so
that Vue can access them. The rest of the templating is then moved into
a Vue single file component. This will make it easier for the developer
to understand the Vue components and make it very clear what is rendered
by Django and what is rendered by Vue.
Previously some of the Vue code relied on script tags being present in
the host application, to include dependencies such as lodash or marked.
This is not ideal for encapsulation since it means the Vue components
are not self-contained, makes testing harder, etc.
As such, this change replaces the script tag includes with ES6 imports.
Additionally, the lodash dependency (which was used only for debouncing)
is replaced in this change with the vue-debounce library which offers a
debouncing directive. This simplifies the code and avoids potential
gotchas with the this context in the debounced function.
