Helper library for Python+Vue Single Page Applications
Project description
vuespa
A combined Python + Vue.js Single Page Application (SPA) framework.
Example usage (from vuespa/__init__.py
):
-
Write Python API:
class Client(vuespa.Client): async def vuespa_on_open(self): print("Client connected!") async def api_shoe(self, arg1): return f'Got {arg1}' vuespa.VueSpa('vue.app', Client).run()
Optionally, may specify
vuespa.VueSpa('vue.app', Client, port=8080).run()
to run on ports 8080 (webserver and websocket) and 8081 (Vue dev server). -
Create app via
vue create vue.app
. -
Edit
vue.app/src/main.ts
(if typescript) with:declare var VueSpaBackend: any; Vue.use(VueSpaBackend);
-
Edit
vue.app/public/index.html
with:<script src="<%= BASE_URL %>vuespa.js"></script>
-
Create
vue.app/src/shims-vuespa.d.ts
, to silence Typescript errors, with:import Vue from 'vue'; declare module 'vue' { export default interface Vue { $vuespa: { call: (fn: string, ...args: any[]), update: (name: string, fn: string, ...args: any[]), }; } }
-
Add calls to the server as:
await this.$vuespa.call('shoe', 32)
-
Run the Python script! This will build the Vue application, run a Python web server on a random port, and point your web browser at the deployment.
As a shortcut in e.g. template callbacks, can use $vuespa.update('propName', 'shoe', 32)
to place the call to api_shoe
and then set the resulting value in propName
.
History:
- 2020-04-02 - 0.2.8 release. Production mode no longer runs 'npm install' if dist folder exists already.
- 2020-02-04 - 0.2.7 release. Fixed an error from moving to aiohttp websocket. Fixed vue serve hot reloading.
- 2020-01-06 - 0.2.6 release. A few things:
- Use IPv4 host by default, since e.g. Docker has issues with IPv6.
- Only use one port (instead of one for HTTP and a separate port for websocket). This is to make Docker usage easier. Note that for development, the Vue development port will not be forwarded by default.
- 2019-12-18 - 0.2.5 release built. Better documentation (shows $vuespa.call), and randomly select port unless otherwise specified.
- 2019-10-21 - 0.2.3 release.
