Get Salesforce ContentVersion file info using node-fetch

Reading Time: < 1 minutes

Let’s say you want to get the file info without downloading it. For example, you want to know the file name and extension.
The way to do it is to make a request to:
First, let’s have a method to get the access token
const getJsForceConnection = async () => {
    const username = "******";
    const password = "******";
    const securityToken = "******";

    const salesforceUrl = "";
    const salesforceApiVersion = "52.0";

    const options = {instanceUrl: salesforceUrl, loginUrl: salesforceUrl, version: salesforceApiVersion};
    const conn = new jsForce.Connection(options);
    await conn.login(username, password + securityToken);

    return conn;
And then let’s make a request to get the file info with node-fetch
const getFileInfo = async (conn, salesforceFileId, salesforceApiVersion) => {
    const url = `${conn.instanceUrl}/services/data/v${salesforceApiVersion}/sobjects/ContentVersion/${salesforceFileId}`;
    const ops = {
        method: 'GET',
        headers: {
            'Content-Type': 'application/json',
            'Authorization': 'OAuth '+conn.accessToken
    const res = await fetch(url, ops);

    if(!res.ok) throw new Error(`error getting file info from ${url} status code: ${res.status} status message ${res.statusText}`);

    const json = await res.json();
    return {
        fileTitle: json.Title,
        fileName: `${json.Title}.${json.FileExtension}`,
        fileExtension: json.FileExtension,
        fileId: salesforceFileId,
