Using Vue and jsmind to implement multi-language and international support for mind maps

With the development of globalization, multi-language and international support for software has become One of the increasingly important requirements. When developing mind mapping applications, providing multilingual and international support will provide users with a better experience. This article will introduce how to use Vue and jsmind libraries to implement multi-language and international support for mind maps.

First of all, we need to prepare some tools and resources. We will use Vue as the front-end framework to develop the mind mapping application, and use the jsmind library to implement the mind mapping function. To achieve multi-language and internationalization support, we will use the Vue-i18n library to manage the application's languages.

Before using Vue, you first need to install Vue-cli. You can execute the following command through the command line to install:

npm install -g @vue/cli

After the installation is complete, we can create a Vue project through the following command:

vue create my-mindmap

Next, we need to install jsmind and Vue- i18n library. It can be installed with the following command:

npm install jsmind vue-i18n

Now, we are ready to start development.

First, we need to introduce the Vue-i18n and jsmind libraries into the root component of Vue. You can add the following code to the main.js file:

import Vue from 'vue'
import VueI18n from 'vue-i18n'
import jsmind from 'jsmind'

Vue.use(VueI18n)
Vue.prototype.$jsmind = jsmind

Then, create an i18n directory under the src directory and create a lang.js file in it to store multi-language configuration. Configurations for different languages ​​can be added as needed. For example:

export default {
  en: {
    message: {
      hello: 'Hello',
      world: 'World'
    }
  },
  zh: {
    message: {
      hello: '你好',
      world: '世界'
    }
  }
}

Next, create a components directory in the src directory, and create a Mindmap.vue file in it to implement the mind map component. You can add the following code to the file:

<template>
  <div class="mindmap">
    <div class="mindmap-title">{{ $t('message.hello') }}</div>
    <div class="mindmap-content">{{ $t('message.world') }}</div>
    <div class="mindmap-container" ref="mindmap"></div>
  </div>
</template>

<script>
export default {
  mounted() {
    const options = {
      container: 'mindmap',
      editable: true,
      theme: 'default',
    }
    const mind = this.$jsmind.show(options)
  }
}
</script>

<style scoped>
.mindmap {
  width: 100%;
  height: 100%;
  display: flex;
  flex-direction: column;
  align-items: center;
  justify-content: center;
}

.mindmap-title {
  font-size: 24px;
  font-weight: bold;
}

.mindmap-content {
  font-size: 18px;
  margin-top: 10px;
}

.mindmap-container {
  width: 600px;
  height: 400px;
  margin-top: 20px;
}
</style>

In the above code, we use Vue's internationalization feature to achieve multi-language support. Output the corresponding internationalized text by using {{ $t('message.hello') }} in the template.

Now, we need to use our mind map component in the App.vue file. The following code can be added to the template of the App.vue file:

<template>
  <div id="app">
    <Mindmap />
  </div>
</template>

Finally, configure Vue-i18n in the main.js file and load the multi-language configuration. You can add the following code in the main.js file:

import Vue from 'vue'
import App from './App.vue'
import VueI18n from 'vue-i18n'
import lang from './i18n/lang'

Vue.config.productionTip = false

const i18n = new VueI18n({
  locale: 'en',
  messages: lang
})

new Vue({
  i18n,
  render: h => h(App),
}).$mount('#app')

In the above code, we load the multi-language configuration in the lang.js file into Vue-i18n.

Now we have completed multi-language and international support for mind maps. You can run the Vue project through the following command:

npm run serve

After executing the above command, we can visit http://localhost:8080 in the browser to view our multi-language and international mind mapping application .

It is very simple to use Vue and jsmind to implement multi-language and international support for mind maps. By using the Vue-i18n library to manage multilingual and internationalization configurations, and using the $t method in the template to output the corresponding internationalized text, we can easily implement multilingualization of the mind map application and internationalization support.
