Read rows from Google BigTable

Used integrations:
class GoogleBigtableSourceGetRows {
async init() {
// TODO: Create your google-bigtable credential
// More info at https://yepcode.io/docs/integrations/google-bigtable/#credential-configuration
const googleBigTable = yepcode.integration.googleBigTable(
"your-google-bigquery-bigtable-name"
);
// TODO: Customize your instance and table names
this.table = await googleBigTable
.instance("your-instance-name")
.table("your-table-name");
}

async fetch(publish, done) {
// You can customize get options. eg: get matching keys
// Look at: https://cloud.google.com/nodejs/docs/reference/bigtable/latest/bigtable/getrowsoptions
const getRowsOptions = {};
const [rows] = await this.table.getRows(getRowsOptions);

for (const rowResponse of rows) {
const [row] = await rowResponse.get();
const item = this._mapRowToItem(row);
await publish(item);
}
done();
}

_mapRowToItem(row) {
const columnsAndLastValue = Object.entries(row.data).map(
([columnName, columnContent]) => [
columnName,
this._getLastColumnValue(columnContent),
]
);
return Object.fromEntries(columnsAndLastValue);
}

_getLastColumnValue(columnContent) {
// The second [0] is to access the last value
// You can access previous values by accessing the next
// elements in the list
return columnContent[0][0].value;
}

async close() {}
}

Insert rows into Xata table

Used integrations:
class HttpTargetXataInsert {
async init() {
// TODO: Create your http credential with xata information:
// More info at https://yepcode.io/docs/integrations/http/#credential-configuration
// baseUrl: Your Xata.io base url https://${your-workspace}.${your-zone}.xata.sh/db'
// HTTP Headers: { "Authorization": "Bearer <your-xata-api-key>" }
this.httpClient = yepcode.integration.http(
"your-http-xata-credential-name"
);
}

async consume(item) {
// TODO: Set your table endpoint parameters
// You may check API documentation for more details
// https://xata.io/docs/overview
const database = "<your-database>";
const branch = "<your-branch>";
const table = "<your-table>";

await this.httpClient
.post(`/${database}:${branch}/tables/${table}/data`, item)
.catch((error) => {
console.error(
`An error was thrown inserting data`,
error.response.data
);
throw error;
});
}

async close() {}
}

YepCode is a SaaS platform that enables the creation, execution and monitoring of integrations and automations using source code in a serverless environment.

We like to call it the Zapier for developers, since we bring all the agility and benefits of NoCode tools (avoid server provisioning, environment configuration, deployments,...), but with all the power of being able to use a programming language like JavaScript or Python.

These recipes are an excellent starting point for creating your own YepCode processes and solving complex integration and automation problems.

You only have to complete the sign up form and your account will be created with our FREE plan (no credit card required).

YepCode has been created with a clear enterprise focus, offering a multi-tenant environment, team management capabilities, high security and auditing standards, Identity Provider (IdP) integrations, and on-premise options. It serves as the Swiss army knife for engineering teams, especially those requiring the extraction or transmission of information to external systems. It excels in scenarios demanding flexibility and adaptability to change within the process.

Sure! You only need to configure YepCode servers to establish a connection with that service. Check our docs page to get more information.
