JSDocs

/**
 * @name transpileInjector
 *
 * @description This async function ingests a file, accepts an object to
 * inject into the file, updates the AST and writes to the target file.
 *
 * @example
 *
 *    // thenable
 *    transpileInjector({
 *      strategy: 'merge',
 *      baseType: ReturnStatement,
 *      strict: false
 *    },
 *    infile,
 *    outfile
 *    injection).then(msg => {
 *      if (!msg.exitCode === 0) {
 *        // didn't work
 *      }
 *    })
 *
 *    // async
 *    const exit = await transpileInjector(opts, inpath, outpath, injection)
 *
 * @param {string} inFile - original file path prepared for OS
 * @param {string} outFile - target filepath prepared for OS
 * @param {(object|string)} injection - object to inject
 * @param {Object} opts
 * @param {string} opts.strategy - [merge|skip]
 * @param {string} opts.baseType - ensure node type
 * @param {boolean} opts.strict - process.exit(1) on any error
 * @returns {Promise<{errMsg: *, exitCode: number}>}
