# Development
|
|
|
|
Please as a first start, tell the community about your intent to develop a feature or fix a bug. Search for the associated issue if it exists or open one with steps to reproduce (for bugs) or a [user story](https://en.wikipedia.org/wiki/User_story#Principle) (for features).
|
|
|
|
## Setup
|
|
|
|
### Prerequisites
|
|
|
|
To setup your environment, you would need to install the following dependencies:
|
|
- git
|
|
- [nvm](https://github.com/nvm-sh/nvm/blob/master/README.md) (recommended) or nodejs installed on your system
|
|
- Chromium to run the end-to-end tests
|
|
- Python (preferably Python 3.11, minimum 3.9) and virtualenv
|
|
|
|
### Clone the repository
|
|
|
|
```bash
|
|
$ git clone https://github.com/gristlabs/grist-core
|
|
```
|
|
|
|
And then, enter the grist-core root directory:
|
|
|
|
```bash
|
|
$ cd grist-core/
|
|
```
|
|
|
|
### Setup nodejs
|
|
|
|
#### Using nvm (recommanded)
|
|
|
|
You need to install the supported nodejs version as well as yarn. To do so, in the grist-core root directory, run the following command to install nodejs via nvm:
|
|
|
|
```bash
|
|
$ nvm install
|
|
```
|
|
|
|
Now check that node is installed in the version specified in the `.nvmrc` file:
|
|
|
|
```bash
|
|
$ node --version
|
|
```
|
|
|
|
Then install yarn (the `-g` flag here means that yarn will be available globally):
|
|
```bash
|
|
$ npm install -g yarn
|
|
```
|
|
|
|
Now each time you want to load nodejs and yarn in your environment, just run the following command at grist-core root directory:
|
|
|
|
```bash
|
|
$ nvm use
|
|
```
|
|
|
|
#### Using nodejs
|
|
|
|
You can also use nodejs installed in your system. To prevent incompatibilities, ensure that the `node --version` command reports a version equal or greater to the one in `.nvmrc`.
|
|
|
|
### Install the python packages
|
|
|
|
Be sure to have Python and virtualenv installed. On debian-based Linux distributions, you can simply run the following command as root:
|
|
|
|
```bash
|
|
# apt install python3.11 python3.11-venv
|
|
```
|
|
|
|
### Install the project dependencies and build
|
|
|
|
First install the nodejs dependencies:
|
|
|
|
```bash
|
|
$ yarn install
|
|
```
|
|
|
|
Then prepare the virtual environment with all the python dependencies:
|
|
|
|
```bash
|
|
$ yarn install:python
|
|
```
|
|
|
|
Finally run this to do an initial build:
|
|
|
|
```bash
|
|
$ yarn run build:prod
|
|
```
|
|
|
|
## Start the server in development mode
|
|
|
|
Just run the following command:
|
|
```bash
|
|
$ yarn start
|
|
```
|
|
|
|
Each time you change something, just reload the webpage in your browser.
|
|
|
|
Happy coding!

|
## Debug the server
|
|
|
|
You can debug the NodeJS application using this command:
|
|
|
|
```bash
|
|
$ yarn start:debug
|
|
```
|
|
|
|
And start using your nodejs debugger client (like the Chrome Devtools). See https://nodejs.org/en/docs/guides/debugging-getting-started#inspector-clients
|
|
|
|
## Run tests
|
|
|
|
You may run the tests using one of these commands:
|
|
- `yarn test` to run all the tests
|
|
- `yarn test:smoke` to run the minimal test checking Grist can open, create and edit a document
|
|
- `yarn test:nbrowser` to run the end-to-end tests
|
|
- `yarn test:client` to run the tests for the client libraries
|
|
- `yarn test:common` to run the tests for the common libraries shared between the client and the server
|
|
- `yarn test:server` to run the backend tests
|
|
- `yarn test:docker` to run some end-to-end tests under docker
|
|
- `yarn test:python` to run the data engine tests
|
