Create a repository for your extension from this template.

Run:

php init.php

It will ask to enter an extension name and some other information.

After that, you can remove init.php file from your repository. Commit changes and proceed to configuration & building.

Create config.json file in the root directory. You can copy config-default.json and rename it to config.json.

When reading, this config will be merged with config-default.json. You can override default parameters in the created config.

Parameters:

• espocrm.repository - from what repository to fetch EspoCRM;
• espocrm.branch - what branch to fetch (stable is set by default); you can specify version number instead (e.g. 5.9.2);
• database - credentials of the dev database;
• install.siteUrl - site url of the dev instance;
• install.defaultOwner - a webserver owner (important to be set right);
• install.defaultGroup - a webserver group (important to be set right).

You can override EspoCRM config. Create config.php in the root directory of the repository. This file will be applied after EspoCRM installation (when building).

Example:

<?php
return [
    'useCacheInDeveloperMode' => true,
];

After building, EspoCRM instance with installed extension will be available at site directory. You will be able to access it with credentials:

• Username: admin
• Password: 1

1. You need to have node, npm, composer installed.
2. Run npm install.
3. Create a database. Note that without the created database instance building will fail. The database name is set in the config file. You can change it.

It will download EspoCRM (from the repository specified in the config), then build and install it. Then it will install the extension.

Command:

node build --all

Note: It will remove a previously installed EspoCRM instance, but keep the database intact.

Note: If an error occurred, check site/data/logs/ for details. It's often a database is not created.

You need to run this command every time you make changes in src directory and you want to try these changes on Espo instance.

Command:

node build --copy

You can set up a file watcher in your IDE to avoid running this command manually. See below about the file watcher.

AfterInstall.php will be applied for EspoCRM instance.

Command:

node build --after-install

Command:

node build --extension

The package will be created in build directory.

Note: The version number is taken from package.json.

If your extension requires other extensions, there is a way to install them automatically while building the instance.

Necessary steps:

1. Add the current EspoCRM version to the config.php:

<?php
return [
    'version' => '9.0.0',
];

2. Create the extensions directory in the root directory of your repository.
3. Put needed extensions (e.g. my-extension-1.0.0.zip) in this directory.

Extensions will be installed automatically after running the command node build --all or node build --install.

1. Do development in src dir.
2. Run node build --copy.
3. Test changes in EspoCRM instance at site dir.

You can block out new entity types right in Espo (using Entity Manager) and then copy generated custom files (site/custom dir) to the repository (src dir) using copy-custom.js script.

1. Create entity types, fields, layouts, relationships in Espo (it should be available in site dir after building).
2. Run node copy-custom.js. It will copy all files from site/custom to src/files/custom/Espo/Modules/{ModuleName} and apply needed modifications to files.
3. Remove files from site/custom.
4. Run node build --copy. It will copy files from the repository to Espo build (site/custom//Espo/Modules/{ModuleName} dir).
5. Clear cache in Espo.
6. Test in Espo.
7. Commit changes.

You can remove copy-custom.js from the repository if you don't plan to use it future.

If your extension requires additional libraries, they can be installed by composer:

1. Create a file src/files/custom/Espo/Modules/{ModuleName}/composer.json with your dependencies.
2. Once you run node build --all or node build --composer-install, composer dependencies will be automatically installed.
3. Create a file src/files/custom/Espo/Modules/{ModuleName}/Resources/autoload.json.

Note: The extension build will contain only the vendor directory without the composer.json file.

The autoload.json file defines paths for namespaces:

{
    "psr-4": {
        "LibraryNamespace\\": "custom/Espo/Modules/{ModuleName}/vendor/<vendor-name>/<library-name>/path/to/src"
    }
}

The version number is stored in package.json and package-lock.json.

Bumping version:

npm version patch
npm version minor
npm version major

Run composer install:

`(cd site; composer install)`

Command to run unit tests:

(node build --copy; node build --composer-install; cd site; vendor/bin/phpunit tests/unit/Espo/Modules/{@name})

You need to build a test instance first:

1. node build --copy
2. (cd site; grunt test)

You need to create a config file tests/integration/config.php:

<?php

return [
    'database' => [
        'driver' => 'pdo_mysql',
        'host' => 'localhost',
        'charset' => 'utf8mb4',
        'dbname' => 'TEST_DB_NAME',
        'user' => 'YOUR_DB_USER',
        'password' => 'YOUR_DB_PASSWORD',
    ],
];

Command to run integration tests:

(node build --copy; node build --composer-install; cd site; vendor/bin/phpunit tests/integration/Espo/Modules/{@name})

Command to run:

node build --copy; node build --composer-install; site/vendor/bin/phpstan

If your extension contains additional PHP packages, you also need to add site/custom/Espo/Modules/{@name}/vendor to the scanDirectories section in phpstan.neon config.

Note: You can ommit composer-install command if your extension does not contain PHP packages.

You need to set the following paths to be ignored in your IDE:

• build
• site/build
• site/custom/
• site/client/custom/
• site/tests/unit/Espo/Modules/{@name}
• site/tests/integration/Espo/Modules/{@name}

You can set up a file watcher in the IDE to automatically copy and transpile files upon saving.

File watcher parameters for PhpStorm:

• Program: node
• Arguments: build --copy-file --file=$FilePathRelativeToProjectRoot$
• Working Directory: $ProjectFileDir$

As of v8.0.

The initialization script asks whether you want to use ES6 modules. If you choose "NO", you still can switch to ES6 later:

1. Set bundled to true in extension.json.
2. Set bundled and jsTranspiled to true in src/files/custom/Espo/Modules/{@name}/Resources/module.json.
3. Add src/files/custom/Espo/Modules/{@name}/Resources/metadata/app/client.json

   {
       "scriptList": [
           "__APPEND__",
           "client/custom/modules/{@nameHyphen}/lib/init.js"
       ]
   }
