Discord.js | How to create a MessageEmbed with unknown amount of Fields?-CodePudding

I'm new to NodeJS and use it for my Discord bot. My goal is to reply to a command with an embed that has dynamic fields (depending on how many values I have). My approach was to pass an array that matches the Discord API's format to the MessageEmbed().addFields() function. This is what my JSON stringyfied array looks like:

[{"name":"eur","value":1176,"inline":false},{"name":"btc","value":0.0001,"inline":false}]

Which results in this error: TypeError: Cannot read properties of undefined (reading 'name')

That's because Discord doesn't want the Object's property names as strings. The output that I'd need would be: [{name:"eur",value:1176,inline:false},{name:"btc",value:0.0001,inline:false}]

Is there a way to pass the object's property names as 'non-strings'? Or should I approach it completely different?

Here is an example of a MessageEmbed:

interaction.reply({embeds: [
                    new MessageEmbed()
                    .setTitle("Server Info")
                    .addFields([
                            {
                                name: "Channels",
                                value: `${interaction.guild.channels.cache.size}`
                            },
                            {
                                name: "Members",
                                value: `${interaction.guild.members.cache.size}`
                            },
                            {
                                name: "Created",
                                value: `<t:${Math.round(interaction.guild.createdTimestamp / 1000)}>`,
                                inline: true
                            }
                        ])
                    ]})

In my case I don't know how many fields there are gonna be. Thats why i need some solution that works for an unknown amount of fields.

CodePudding user response：

Each MessageEmbed can have up to 25 fields, so you can either slice your array to that value, or send multiple embeds.

It's very simple. Just, instead of using the quotes to make strings, remove them.

Important: Only 25 fields or less are allowed per embed.

const fields = [
   {
      name: "Channels",
      value: `${interaction.guild.channels.cache.size}`
   },
   {
      name: "Members",
      value: `${interaction.guild.members.cache.size}`
   },
   {
      name: "Created",
      value: `<t:${Math.round(interaction.guild.createdTimestamp / 1000)}>`,
      inline: true
   }
]

 interaction.reply({embeds: [
      new MessageEmbed()
          .setTitle("Server Info")
          .setDescription("Here is the server info:")
          .addFields(fields)
  })
