About the method of Vue2 SSR caching Api data
This article mainly introduces Vue2 SSR cache Api data. The content is quite good. I will share it with you now and give it as a reference.
This article introduces the Vue2 SSR cache API data and shares it with everyone. The details are as follows:
1. Install cache dependency: lru-cache
npm install lru-cache --dev
2. api configuration file
config-server.js
var LRU = require('lru-cache')
let api
if (process.__API__) {
api = process.__API__
} else {
api = process.__API__ = {
api: 'http://localhost:8080/api/',
cached: LRU({
max: 1000,
maxAge: 1000 * 60 * 15
}),
cachedItem: {}
}
}
module.exports = apiConfigure lru-cache
3. Encapsulate the api
import axios from 'axios'
import qs from 'qs'
import md5 from 'md5'
import config from './config-server.js'
export default {
post(url, data) {
const key = md5(url + JSON.stringify(data))
if (config.cached && config.cached.has(key)) {
return Promise.resolve(config.cached.get(key))
}
return axios({
method: 'post',
url: config.api + url,
data: qs.stringify(data),
// 其他配置
}).then(res => {
if (config.cached && data.cache) config.cached.set(key, res)
return res
})
}
}We use axios for the ajax library, because axios can be used in nodejs and browsers
And encapsulate the node side and the browser side separately
import config from './config-server.js'
const key = md5(url + JSON.stringify(data))
Generate a through url and parameters The only key
if (config.cached && config.cached.has(key)) {
return Promise.resolve(config.cached.get(key))
}if (config.cached && data.cache) config.cached.set(key, res)
Determine whether the cache is enabled, and if the interface specifies cache, it will The data returned by the api is written to the cache
Note:
This api will handle all requests, but many requests do not actually need to be cached, so If you need to cache, you can add cache: true in the passed data, such as:
api.post('/api/test', {a: 1, b:2, cache: true})If you don’t need caching, just pass the value as normal
Of course there are many ways to mark whether to cache, you don’t have to use this one
