Create
Creating a bot is as simple as running the following command and following the instructions
pnpm create builderbot@latest
Use the space key to select and the enter key to confirm. The CLI performs a preliminary check of the Node and operating system version, informing you if it meets the requirements or providing you with relevant information. In addition to generating a base project for you to simply start up
If you have problems with your terminal try running the command with CMD, PowerShell, GitBash or another console you have installed.
Requirements
Make sure you have installed Node version 20 or higher, below you can see an example to check the version of node you are using.
Node Version
node -v
v20.10.0
It is recommended to have GIT installed for proper operation. If you are using Linux or MacOc you probably already have GIT installed by default.
Git Version
git -v
git version XXXX
Base Example
In this example we can see the basis of a simple bot which responds to the keywords sent by a user, the words are: info, hello, hi. You can see how to create the bot and implement the flows.
import { createBot, createProvider, createFlow, addKeyword, MemoryDB } from '@builderbot/bot'
import { BaileysProvider } from '@builderbot/provider-baileys'
/** send static messages */
const welcomeFlow = addKeyword<BaileysProvider, MemoryDB>(['hello', 'hi']).addAnswer('Ey! welcome')
/** send dynamic message from db or other sources */
const infoFlow = addKeyword<BaileysProvider, MemoryDB>('info')
.addAction(async (ctx, { flowDynamic }) => {
await flowDynamic(`Welcome ${ctx.name}`)
})
/** send media files */
const mediaFlow = addKeyword<BaileysProvider, MemoryDB>('image')
.addAnswer(`Send Image A`, { media: 'https://i.imgur.com/AsvWfUX.png' })
.addAction(async (ctx, { flowDynamic }) => {
await flowDynamic(`Welcome ${ctx.name}`)
await flowDynamic(
[
{
body: 'Send Image B',
media: 'https://i.imgur.com/w0RtKnN.png'
}
]
)
})
/** initialization bot */
const main = async () => {
const adapterDB = new MemoryDB()
const adapterFlow = createFlow([welcomeFlow, infoFlow, mediaFlow])
const adapterProvider = createProvider(BaileysProvider)
adapterProvider.initHttpServer(3000)
await createBot({
flow: adapterFlow,
provider: adapterProvider,
database: adapterDB,
})
}
main()
