我正在制作一个小型应用程序,该应用程序使用sqlite3获取/存储数据。
在开发阶段,一切都很好。但是,当我使用electron-packager打包应用程序时,sqlite3
不再起作用。
这是我的渲染器配置:
return {
target: 'electron-renderer',
mode: argv.production ? 'production' : 'development',
context: paths.root,
devtool: !argv.production ? 'source-map' : false,
entry: {
'app': path.resolve(paths.app, 'app.js')
},
optimization: {
runtimeChunk: false,
splitChunks: {
chunks: 'all',
cacheGroups: {
default: {
enforce: true,
priority: 1
},
vendors: {
test: /[\\/]node_modules[\\/]/,
priority: 2,
name: 'vendors',
enforce: true,
chunks: 'async'
}
}
}
},
module: {
rules: require('./rule')(paths, argv).get()
},
plugins: require('./plugin')(paths, argv).get(),
output: {
path: paths.dist,
filename: 'app.bundled.js'
},
resolve: {
// Add `.ts` and `.tsx` as a resolvable extension.
extensions: [".ts", ".tsx", ".js"],
alias: {
// summernote: codemirror
'CodeMirror': 'codemirror',
}
},
watch: !argv.production,
watchOptions: {
poll: false
},
externals: {
sqlite3: 'commonjs sqlite3'
}
};
这是属于渲染器进程的文件,其中包括sqlite3
:
const typeorm = require('typeorm');
const EntitySchema = typeorm.EntitySchema;
const path = require('path');
const electron = require('electron');
require('sqlite3');
module.exports = (ngModule) => {
ngModule.service('$db', (toastr) => {
//#region Properties
// Instance of database connection
let dbConnection = null;
//#endregion
let out = {
//#region Methods
if (dbConnection == null || forceReinitialize) {
// Build a absolute path to database.
const appPath = electron.remote.app.getAppPath();
const dbPath = path.join(appPath, 'assets/db/PersonalCv.db');
return typeorm
.createConnection({
type: "sqlite",
database: dbPath,
synchronize: false,
entities: [
new EntitySchema(require('../models/entities/user')),
new EntitySchema(require('../models/entities/user-decription')),
new EntitySchema(require('../models/entities/skill-category')),
new EntitySchema(require('../models/entities/skill')),
new EntitySchema(require('../models/entities/personal-skill')),
new EntitySchema(require('../models/entities/project')),
new EntitySchema(require('../models/entities/project-skill')),
new EntitySchema(require('../models/entities/project-responsibility')),
new EntitySchema(require('../models/entities/responsibility'))
]
})
.then((connection) => {
dbConnection = connection;
return dbConnection;
})
.catch((error) => {
toastr.error(error);
throw error;
});
}
return new Promise(resolve => {
resolve(dbConnection);
});
},
/*
* Get repository by using name (table name)
* */
getRepository: (name) => {
return out
.getConnection()
.then((connection) => {
return connection.getRepository(name);
});
}
//#endregion
};
return out;
});
};
如果有人需要进一步的信息,这是我的repo。
有人可以帮我吗?
谢谢

sqlite3是一个本地模块,具体取决于系统体系结构。 Electron-packager并没有做任何特殊的事情来帮助您编译本机模块。
因此您可以使用https://github.com/kripken/sql.js/之类的纯JS SQLite软件包
或者尝试使用带有“安装后”脚本的电子构建器:https://github.com/electron-userland/electron-builder。
另请参阅:https://electronjs.org/docs/tutorial/using-native-node-modules

经过electron-packager
和electron-builder
的一些问答。我找到了一种使sqlite3
与webpack
一起使用的解决方案。
在webpack.config.js
中,我添加了:
externals: {
sqlite3: 'commonjs sqlite3'
}
我使用electron-packager
而不是electron-builder
来构建我的应用程序。在build
配置中,我将sqlite3
模块复制到dist
文件夹中。
