B4J Library [Web]PocketBase Hooks Collection

Hi Fam

This will be a collection of useful hooks to use with pocketbase.

The hooks should be saved in the pb_hooks folder of your pocketbase server. Create js files with the respective routes and restart the server.

What is PocketBase?

Ola. Its amazing with the latest version of PocketBase one can extend it with JavaScript / Go. So I tested creating some REST API handlers. You can unzip the attached file to your pocketbase folder. It should create a pb_hooks folder. You can then call the handler via the browser after...

1. Send An Email via REST API with GMail or Other

One is able to send emails using pocketbase & gmail for example. Any other SMTP based configuration can be used.

Unzip and copy the attached script to your pb_hooks directory inside pocketbase folder.
You will need to restart your app after.

routerAdd("POST", "/api/sendemail", (c) => {
    try {
        // read the body via the cached request object
        const data = $apis.requestInfo(c).data
        const message = new MailerMessage({
            from: {
                address: $app.settings().meta.senderAddress,
                name: $app.settings().meta.senderName,
            },
            to: [{ address: data.to }],
            subject: data.subject,
            html: data.message
        })
        $app.newMailClient().send(message)
        return c.json(200, { "email": "Success" })
    } catch (err) {
        return c.json(200, { "email": "Failure", "error": err })
    }
}, $apis.activityLogger($app))

This code receives a JSON via REST API (body) with {to, subject, message}

Execute a POST using

2. Delete All Records in a Table

Deletion of all records in a table is currently NOT YET supported. To delete all the records, one has to get all the record IDs and then delete EACH one individually. This hook enables one to pass the name of the table to "truncate" and delete all the records.

This is open to SQL attacks, so be careful and use with caution.

OPTION 1, add middleware to ensure that deletion happens by an admin user.

routerAdd("POST", "/api/deleteallauth", (c) => {
    try {
        const data = $apis.requestInfo(c).data
        const tablename = data.tablename
        if (tablename.length > 0) {
            $app.dao().db()
                .newQuery("DELETE FROM " + tablename)
                .execute()
            return c.json(200, { "deleteall": "Success" })
        } throw new BadRequestError("The tablename has not been specified!")
    } catch (err) {
        return c.json(400, { "deleteall": "Failure", "error": err })
    }
}, $apis.activityLogger($app),$apis.requireAdminAuth())

OPTION 2, ...

routerAdd("POST", "/api/deleteall", (c) => {
    try {
        const data = $apis.requestInfo(c).data
        const tablename = data.tablename
        if (tablename.length > 0) {
            $app.dao().db()
                .newQuery("DELETE FROM " + tablename)
                .execute()
            return c.json(200, { "deleteall": "Success" })
        } throw new BadRequestError("The tablename has not been specified!")
    } catch (err) {
        return c.json(400, { "deleteall": "Failure", "error": err })
    }
}, $apis.activityLogger($app))

The body should be a JSON with

{
    "tablename":"components"
}

Where for example "components" is your table name.

Execute a POST using

http://127.0.0.1:9090/api/deleteall

http://127.0.0.1:9090/api/deleteallauth

Get the server date time

This code returns the current server date time as a string

routerAdd("GET", "/api/servertime", (c) => {
    const now = new Date()
    const year = now.getFullYear()
    const month = String(now.getMonth() + 1).padStart(2, '0')
    const day = String(now.getDate()).padStart(2, '0')
    const hours = String(now.getHours()).padStart(2, '0')
    const minutes = String(now.getMinutes()).padStart(2, '0')
    const formattedDateTime = `${year}-${month}-${day} ${hours}:${minutes}`
    return c.string(200, formattedDateTime)
}, $apis.activityLogger($app))

To call it:

http://127.0.0.1:1001/api/servertime

Result:
