# Service Library - `jobApplication`

This document provides a complete reference of the custom code library for the `jobApplication` service. It includes all library functions, edge functions with their REST endpoints, templates, and assets.


## Library Functions

Library functions are reusable modules available to all business APIs and other custom code within the service via `require("lib/<moduleName>")`.


### `hasUserAlreadyApplied.js`

```js
module.exports = async function(userId, jobPostingId) { const JobApplication = this.getModel('jobApplication'); const app = await JobApplication.findOne({ where: { applicantUserId: userId, jobPostingId: jobPostingId, isActive: true }}); return !!app; }
```


### `getAdminJobPostingIds.js`

```js
module.exports = async function(userId) { const CompanyAdmin = this.getModel('companyAdmin', 'company'); const companies = await CompanyAdmin.findAll({ where: { userId: userId, isActive: true }}); const companyIds = companies.map(a => a.companyId); const JobPosting = this.getModel('jobPosting'); const jobPostings = await JobPosting.findAll({ where: { companyId: { $in: companyIds }, isActive: true }}); return jobPostings.map(jp => jp.id); }
```
