Migration from Valine

About 1 min...

Since Waline completely reuses Valine's data structure in storage, migrating from Valine to Waline is very simple.

  1. Deploy backend according to Vercel Deploy in Get Started section. LEAN_ID and LEAN_KEY should be the same as those applied for when using Valine before. Don't forget to set LEAN_MASTER_KEY for Waline.

  2. Modifiy frontend scripts according to HTML in Get Started section. Please remind we should remove old configuration appId and appKey from Valine, and add serverURL option.

    - <script src='//unpkg.com/valine/dist/Valine.min.js'></script>
    + <script src='//unpkg.com/@waline/client@v2/dist/waline.js'></script>
    + <link href='//unpkg.com/@waline/client@v2/dist/waline.css' rel='stylesheet' />
    
      <script>
    -  new Valine({
    +  Waline.init({
        el: '#vcomments',
    -   appId: 'Your appId',
    -   appKey: 'Your appKey'
    +   serverURL: 'YOUR SERVER URL'
      });
      </script>
    

Config

Waline V2 has removed Valine support and moved to a better configuration. The following is a migration summary of some options:

  • placeholder: use locales.placeholder
  • highlight: use highlighter
  • avatarForce, avatar: use the server's AVATAR_PROXY environment variable
  • recordIP: no longer display the user IP, and provide the DISABLE_USERAGENT environment variable on the server
  • requiredFields: renamed to requiredMeta
  • langMode: renamed to locales
  • emojiCDN, emojiMap: use more powerful emoji options

For waline config, please refer to Client Config. You can also check Waline Client V2 Migration Guide to learn about the options that are not compatible with Valine.

Using Leancloud China

Besides LEAN_ID and LEAN_KEY, you need to config LEAN_SERVER environment variable if you're the user of LeanCloud China.

Also, you need to complete Domain name filing to Local Communications Administration, that needs a Fixed IP。

Migration to Cloudbase

If you want to migrate your Valine data to Tencent Cloud Database, you can use the import function of LeanCloud with the import function of the cloud database. Select Import/Export > Limit to certain classes > Comment > Export in the LeanCloud background, and then you will receive a email notification.

Enter the Tencent Cloud Development Backend → Databaseopen in new window page and select the Comment collection.
