# Composer

## Symlinking the API

Problem: changes made to API code are not reflected in requests, or running `composer update` yields a message stating that there is nothing to do.

* Verify that you have cloned the API to your `~/Sites` directory.
* Verify that you are running the command `composer update elentrapackages/elentra-1x-api` after you have run `composer install`.
* Verify that you have a `composer-api-dev.json` file in the root of your `elentra-1x-me` project.
* Verify the following in your `composer-api-dev.json` file:
  * That the value for `[BRANCH_NAME]` matches the name of the branch that you currently have checked out in the API.
  * That the value for `url` points to the correct path that you cloned the API into.

```javascript
{
  "repositories": [
      {
          "type": "path",
          "url": "../elentra-1x-api",
          "options": {
              "symlink": true
          }
      }
  ],
  "require": {
      "elentrapackages/elentra-1x-api": "dev-[BRANCH_NAME]"
  }
}
```

## Composer Install Errors

You experience a either a 404 or 403 error when attempting to run composer install.

* Ensure that you have set your composer auth token by running

  ```
  composer config --global --auth http-basic.repo.packagist.com token [YOUR_ORGANIZATION_TOKEN]
  ```
* Ensure that you that you are using the private Packagist token provided to your organization by the Elentra Consortium.

## Composer Memory Error

![](/files/-MczPBUxcMIXNL1fKKWj)

{% hint style="danger" %}
`PHP fatal error: Allowed memory size of .... exhausted`
{% endhint %}

Sometimes you may experience the error displayed here when attempting to run a `composer install` or `composer update elentrapackages/elentra-1x-api` . You can easily solve this problem by setting the memory limit to `-1` before your composer command. Example:

```javascript
// This is an example, and it works on other composer commands all the same
COMPOSER_MEMORY_LIMIT=-1 composer update elentrapackages/elentra-1x-api
```
