@rowslint/importer-angular

The Rowslint Angular package provides access to the prebuilt importer component. The package interacts directly with the Rowslint APIs using your API key.

Installation

npm install @rowslint/importer-angular

Usage

Module

Retrieve the API key from the organization page and import RowslintModule with the organization API key in your module

import { RowslintModule } from '@rowslint/importer-angular';

@NgModule({
imports: [RowslintModule.forRoot({ apiKey: 'ORGANIZATION_API_KEY' })]
})

Component

Call the launch() method of the RowslintService service with the template config to display the importer UI.

Import`, }) export class AppComponent { config: RowslintTemplateConfig = { // Your template key here. templateKey: 'TEMPLATE_KEY', }; constructor(private rowslintService: RowslintService) {} import() { this.rowslintService.launch(this.config); } }">import { Component } from '@angular/core';
import { RowslintTemplateConfig, RowslintService } from '@rowslint/importer-angular';

@Component({
selector: 'app-root',
template: ``,
})
export class AppComponent {
config: RowslintTemplateConfig = {
// Your template key here.
templateKey: 'TEMPLATE_KEY',
};

constructor(private rowslintService: RowslintService) {}

import() {
this.rowslintService.launch(this.config);
}
}

Headless UI

You can also use your custom upload UI and then use Rowslint importer only to format and validate data. To do so, call the launch() method with the uploaded file (in file type).

this.rowslintService.launch(this.config, this.file);

Events

RowslintService provides an event to listen to the closing of the importer modal. You can use it to handle the closing of the importer after the import has been completed.

constructor(private rowslintService: RowslintService) {
this.rowslintService.onImport.subscribe((result) => {
switch (result.status) {
case RowslintImportStatus.SUCCESS:
// Handle spreadsheet import success.
break;
case RowslintImportStatus.ERROR:
// Handle spreadsheet import error.
break;
case RowslintImportStatus.CANCELLED:
"// Handle spreadsheet import cancel.
break;
}
});
}

Examples

Importer UI

This example demonstrates how to use the importer by displaying the importer UI and listening on the event when the import process is complete.

Launch`, }) export class AppComponent { config: RowslintTemplateConfig = { templateKey: 'TEMPLATE_KEY', returnType: 'json', }; constructor(private rowslintService: RowslintService) {} launch() { this.rowslintService.launch(this.config); this.rowslintService.onImport.pipe(take(1)).subscribe((resul t) => { if (result.status === 'success' && result.metadata?.is_valid) { // Continue the import process. } }); } }">import { Component } from '@angular/core';
import { take } from 'rxjs';

import { RowslintService, RowslintTemplateConfig } from '@rowslint/importer-angular';

@Component({
selector: 'demo-root',
template: ``,
})
export class AppComponent {
config: RowslintTemplateConfig = {
templateKey: 'TEMPLATE_KEY',
returnType: 'json',
};

constructor(private rowslintService: RowslintService) {}

launch() {
this.rowslintService.launch(this.config);
this.rowslintService.onImport.pipe(take(1)).subscribe((result) => {
if (result.status === 'success' && result.metadata?.is_valid) {
// Continue the import process.
}
});
}
}

Headless importer UI

In this example, we will use the importer in the headless mode. To do so, we will use our custom file input field to upload the file, then we will set it to the importer.

`, }) export class AppComponent { config: RowslintTemplateConfig = { templateKey: 'TEMPLATE_KEY', returnType: 'xslx', }; constructor(private rowslintService: RowslintService) {} launch() { const inputFile = document.getElementById('file'); this.rowslintService.launch(this.config, inputFile?.files?.[0]); this.rowslintService.onImport.pipe(take(1)).subscribe((resul t) => { // Continue the import process. }); } }">import { Component } from '@angular/core';
import { take } from 'rxjs';

import { RowslintService, RowslintTemplateConfig } from '@rowslint/importer-angular';

@Component({
selector: 'demo-root',
template: `


`,
})
export class AppComponent {
config: RowslintTemplateConfig = {
templateKey: 'TEMPLATE_KEY',
returnType: 'xslx',
};

constructor(private rowslintService: RowslintService) {}

launch() {
const inputFile = <HTMLInputElement>document.getElementById('file');
this.rowslintService.launch(this.config, inputFile?.files?.[0]);
this.rowslintService.onImport.pipe(take(1)).subscribe((result) => {
// Continue the import process.
});
}
}

Custom validations

We can define a custom configuration of validations from the code. Let's say our template has a "firstname" column. In this example, we will customize the validation of this column to accept only values starting with the letter "A".

Launch `, }) export class AppComponent { config: RowslintTemplateConfig = { templateKey: 'TEMPLATE_KEY', customValidators: { firstname: (columnValue) => { if (typeof columnValue === 'string' && columnValue.startsWith('A')) { // Return `true` if the value is valid. return true; } // Return custom message if the value is invalid. return { message: 'Must start with the letter "A".', }; }, }, }; constructor(private rowslintService: RowslintService) {} launch() { this.rowslintService.launch(this.config); this.rowslintService.onImport.pipe(take(1)).subscribe((resul t) => { // Continue the import process. }); } }">import { Component } from '@angular/core';
import { take } from 'rxjs';

import { RowslintService, RowslintTemplateConfig } from '@rowslint/importer-angular';

@Component({
selector: 'demo-root',
template: ` `,
})
export class AppComponent {
config: RowslintTemplateConfig = {
templateKey: 'TEMPLATE_KEY',
customValidators: {
firstname: (columnValue) => {
if (typeof columnValue === 'string' && columnValue.startsWith('A')) {
// Return `true` if the value is valid.
return true;
}
// Return custom message if the value is invalid.
return {
message: 'Must start with the letter "A".',
};
},
},
};

constructor(private rowslintService: RowslintService) {}

launch() {
this.rowslintService.launch(this.config);
this.rowslintService.onImport.pipe(take(1)).subscribe((result) => {
// Continue the import process.
});
}
}

Note that:

  • firstname property is the column name and must already be added to the template columns.
  • By defining a column custom validation, this will override the column validation type already defined in the template edition page.

We can also return a list of valid values to be displayed in a select field.

Launch `, }) export class AppComponent { validValues = ['A', 'B']; config: RowslintTemplateConfig = { templateKey: 'TEMPLATE_KEY', customValidators: { firstname: (columnValue) => { if (typeof columnValue === 'string' && validValues.includes(columnValue)) { // Return `true` if the value is valid. return true; } // Return the `this.validValues` array that will be displayed in a select field. return { message: 'Must be "A" or "B".', validationType: 'choiceList', validationOptions: { list: this.validValues, }, }; }, }, }; constructor(private rowslintService: RowslintService) {} launch() { this.rowslintService.launch(this.config); this.rowslintService.onImport.pipe(take(1)).subscribe((resul t) => { // Continue the import process. }); } }">import { Component } from '@angular/core';
import { take } from 'rxjs';

import { RowslintService, RowslintTemplateConfig } from '@rowslint/importer-angular';

@Component({
selector: 'demo-root',
template: ` `,
})
export class AppComponent {
validValues = ['A', 'B'];
config: RowslintTemplateConfig = {
templateKey: 'TEMPLATE_KEY',
customValidators: {
firstname: (columnValue) => {
if (typeof columnValue === 'string' && validValues.includes(columnValue)) {
// Return `true` if the value is valid.
return true;
}
// Return the `this.validValues` array that will be displayed in a select field.
return {
message: 'Must be "A" or "B".',
validationType: 'choiceList',
validationOptions: {
list: this.validValues,
},
};
},
},
};

constructor(private rowslintService: RowslintService) {}

launch() {
this.rowslintService.launch(this.config);
this.rowslintService.onImport.pipe(take(1)).subscribe((result) => {
// Continue the import process.
});
}
}
