Custom writerOpts transform

[asibilia]

I'm trying to write a custom writerOpts.transform to add Jira project links to our change logs. I've tried forking the conventional-changelog/conventional-changelog-angular preset, updating the transform there, and then including my custom conventional changelog preset like so:

// package.json
"release": {
    "branches": [
      "master"
    ],
    "plugins": [
      "@semantic-release/commit-analyzer",
      [
        "@semantic-release/release-notes-generator",
        {
          "config": "@my-team/conventional-changelog-angular-jira", <<<<  custom-npm-package
        }
      ],
      "@semantic-release/changelog",
      "@semantic-release/git",
      [
        "@semantic-release/exec",
       ]
    ],
    "preset": "angular" <<<<  UPDATE...REMOVE_THIS
  }

I've also tried pulling just the transform function out into its own file and referencing it in the writerOpts field like so:

// package.json
"release": {
    "branches": [
      "master"
    ],
    "plugins": [
      "@semantic-release/commit-analyzer",
      [
        "@semantic-release/release-notes-generator",
        {
          "writerOpts": "./writer-opts.js"
        }
      ],
      "@semantic-release/changelog",
      "@semantic-release/git",
      [
        "@semantic-release/exec",
      ]
    ]
  }

// writer-opts.js
const compareFunc = require('compare-func')

module.exports = {
    transform: (commit, context) => {
        let discard = true
        const issues = []

        commit.notes.forEach((note) => {
            note.title = 'BREAKING CHANGES'
            discard = false
        })

        if (commit.type === 'feat') {
            commit.type = 'Features'
        } else if (commit.type === 'fix') {
            commit.type = 'Bug Fixes'
        } else if (commit.type === 'perf') {
            commit.type = 'Performance Improvements'
        } else if (commit.type === 'revert' || commit.revert) {
            commit.type = 'Reverts'
        } else if (discard) {
            return
        } else if (commit.type === 'docs') {
            commit.type = 'Documentation'
        } else if (commit.type === 'style') {
            commit.type = 'Styles'
        } else if (commit.type === 'refactor') {
            commit.type = 'Code Refactoring'
        } else if (commit.type === 'test') {
            commit.type = 'Tests'
        } else if (commit.type === 'build') {
            commit.type = 'Build System'
        } else if (commit.type === 'ci') {
            commit.type = 'Continuous Integration'
        }

        if (commit.scope === '*') {
            commit.scope = ''
        }

        if (typeof commit.hash === 'string') {
            commit.shortHash = commit.hash.substring(0, 7)
        }

        if (typeof commit.subject === 'string') {
            let url = context.repository
                ? `${context.host}/${context.owner}/${context.repository}`
                : context.repoUrl
            if (url) {
                url = `${url}/issues/`
                // Issue URLs.
                commit.subject = commit.subject.replace(
                    /#([0-9]+)/g,
                    (_, issue) => {
                        issues.push(issue)
                        return `[#${issue}](${url}${issue})`
                    }
                )

                // JIRA Ticket
                commit.subject = commit.subject.replace(
                    /([a-zA-Z]+)-(\d+)/,
                    (match, project, number) => {
                        return `[${match}](https://cadence.atlassian.net/browse/${project}-${number})`
                    }
                )
            }
            if (context.host) {
                // User URLs.
                commit.subject = commit.subject.replace(
                    /\B@([a-z0-9](?:-?[a-z0-9/]){0,38})/g,
                    (_, username) => {
                        if (username.includes('/')) {
                            return `@${username}`
                        }

                        return `[@${username}](${context.host}/${username})`
                    }
                )
            }
        }

        // remove references that already appear in the subject
        commit.references = commit.references.filter((reference) => {
            if (issues.indexOf(reference.issue) === -1) {
                return true
            }

            return false
        })

        return commit
    },
    groupBy: 'type',
    commitGroupsSort: 'title',
    commitsSort: ['scope', 'subject'],
    noteGroupsSort: 'title',
    notesSort: compareFunc,
}

Neither of these approaches seem to work. Any thoughts on how best to achieve this would be much appreciated!

UPDATE

For anyone finding this, I got it working after some more experimenting. The custom preset library I made does work but I had to remove "preset": "angular" from my package.json. In case anyone is curious, pointing directly at a file containing the writerOpts.transform method did not work.
